Here, the received MOF is also degassed, and solvent residue of the MOF is removed by placing the received manifold under vacuum conditions (e.g., 10e-5 torr).

(49) Next, at S804 degassing of the MOF is performed by modifying a value of a temperature associated with the received MOF material using a temperature controller to one or more predetermined values of the temperature. For example, the received predetermined amount of the MOF may be heated based on the signals issued by the temperature controller, or the application of a regulated/calibrated heat tape around a reactor vessel containing the received MOF above a first predetermined temperature of about 200 C for a first predetermined time period of between two to eight hours (e.g., overnight).

Simultaneously, the pressure applied to the MOF is maintained at a predetermined pressure value between 12000 torr to about 75000 torr.

(51) The following Table is are examples of varying temperature and pressure ranges, along with the resulting weight percent absortion of tritium, to be discussed in more detail below.

(52) TABLE-US-00001 TABLE 1 Temperature and Pressure Parameters (Examples) Total Absorbed (wt %) Temperature ( C.) Pressure (torr/bar) 1-3 25 75000/100 4 196 12000/16 5 196 45000/60 7 196 75000/100

(53) In an embodiment, based on the table above, the dwell time to hold the temperature and pressure may be for one to two hours at 75000 torr/100 bar and at 298K (near room temperature for tritium uptake to take place.

The manifold may include an inlet channel and an outlet channel. Also, a first end of the inlet channel may be fluidly coupled with the reaction vessel using the first vessel valve. Further, a first end of the outlet channel may be fluidly coupled with the reaction vessel using the second vessel valve.

(55) Further, the method 800 may include a step S810 of modifying, using a pressure controller, a value of a pressure associated with the reaction vessel to one or more required values of the pressure for allowing absorption of at least one amount of the tritium gas into the amount of the MOF material for the producing of the material. Further, the material may be a metal organic framework (MOF)-tritium material.

(57) Next, at S812, evacuation may be performed using a vacuum pump, on the manifold based on a transitioning of the first vessel valve to the open state and a transitioning of the second vessel valve to an open state after the receiving of the MOF material. Evacuation removes a solvent residue of the MOF material from the manifold after the receiving of the MOF material. Also, the supplying of the tritium gas may be based on the applying of the vacuum.

(58) In further embodiments, using a mass flow controller, a value of a mass flow rate of the tritium gas may be modified to one or more required values of the mass flow rate after the supplying of the tritium gas. Further, the absorption of the at least one amount of the tritium gas into the amount of the MOF material may be based on the modifying of the value of the mass flow rate of the tritium gas to the one or more required values of the mass flow rate. Further, the modifying of the value of the mass flow rate modifies the value of the pressure.

(60) In further embodiments, using a pressure sensor of the pressure controller, a pressure associated with the reaction vessel may be detected.

(61) Once evacuation is performed and the pressure reaches atmospheric pressure, at S814 an inert gas such as argon is flushed through the inlet channel to the reaction vessel for at least one duration based on a transitioning a third tank valve of the third tank to an open state, a transitioning of the first vessel valve to the open state, a transitioning of the second vessel valve to the open state, and a transitioning of the second tank valve to a closed state after the detecting an atmospheric pressure value for the pressure.

(62) In an embodiment, the manifold may include a secondary outlet channel. Also, a first end of the secondary outlet channel may be fluidly coupled to the outlet channel using a channel valve. Further, the inert gas may be evacuated from a second end of the secondary outlet channel for flushing the manifold and the reaction vessel based on a transitioning of the channel valve to an open state. Also, the flushing removes a residue amount of the tritium gas from the manifold and the reaction vessel. Further, the metal organic framework (MOF)-tritium material may be retrievable from the reaction vessel after the flushing. Thereafter, at S816, the amount of uptake of the tritium may be measured using a thermal gas absorption instrument.

(63) It is noted that the steps above may be repeated using a different set of temperature and pressure parameters to maximize the tritium uptake per MOF compound.

Further, the cell (column 904, row 908) shows that the material may include the at least one molecule of tritium in an amount of at least 50% by mole based on the total mole of the material.

(68) Also, in some embodiments, the plurality of MOF particles may be characterized by a degree of a physisorption selectivity towards the gas of the tritium.

(75) FIG. 10 illustrates a particle of a material for facilitating generating of electrical energy betavoltaically according to an embodiment.

(76) Referring to FIG. 11, an exemplary Ball-and-Stick structural representation of the MOF-5 is shown, with Hydrogen (H) atoms being omitted for clarity. Here, the exemplary MOF-5 has a Zinc (Zn) inner core including four Zn atoms linked together with an Oxygen (O) at the center amongst the Zn. The Zn inner core is also encircled by additional O atoms (two per Zn atom), each of which is then linked to hydrocarbon/organic carboxylate (e.g., 1, 4 benzenedicarboxylate) including Carbon (C) and additional O atoms.

(77) The formula for synthesizing the MOF-5 may written follows:

(78) ##STR00001## where BDC=1,4 benzenedicarboxylate.

(79) The three-dimensional structure of the MOF-5 forms pores or voids in which tritium may be stored. Here, the tritium is not chemically bonded to another atom within the MOF-5, rather it is stored through chemical adsorption, a process resulting from a chemical chemical bond between the tritium and an active site of the MOF-5, in this case the pores within the MOF-5.

(80) The advantage of using MOF-5 for storing tritium is that MOF-5 has a high hydrogen uptake. In particular, the MOF-5 has a strong affinity to hold the tritium within its pores, and allows for a large amount of tritium to be stored within a given volume of space. This is unlike other MOFs, which are selective towards other gases and/or compounds.

(81) Referring to FIG. 12, an exemplary Ball-and-Stick structural representation of the MOF-200 is shown, with Hydrogen (H) atoms being omitted for clarity. Here, the MOF has the same Zinc (Zn) inner core including four Zn atoms linked together with an Oxygen (O) at the center amongst the Zn. The Zn inner core is also encircled by additional O atoms (two per Zn atom), each of which is then linked to the four hydrocarbon/organic carboxylate groups (e.g., 4,44-(Benzene-1,3,5-triyl-tris (benezene-4, 1-diyl)) tribenzoic acid including Carbon (C) and additional O atoms.

(82) The formula for synthesizing the MOF-200 may written follows:

(83) ##STR00002## where BBC=4,4,4-(Benzene-1,3,5-triyl-tris (benzene-4,1-diyl)) tribenzoic acid.

(84) Even more than the MOF-5, the MOF-200 has an even higher hydrogen uptake than the MOF-5 at room temperature. In particular, the MOF-200 has a stronger affinity than the MOF-5 to hold the tritium within its pores, and also allows for a larger amount of tritium to be stored within an increased volume of space, when compared to other MOFs, which are selective towards other gases and/or compounds.

(85) Additionally, when a light metal such as Li+ is used within the MOF-200, gravimetric can greatly increase. For example, hydrogen uptake can almost double by using Li+ when compared to a traditional transition metal core within the MOF structure.

(86) The physical properties of the above-described exemplary MOFs are shown in the table below:

(87) TABLE-US-00002 Molecular Surface Gravimetric Compound Weight Chemical Area Capacity Identification (g/mol) Formula (m.sup.2/g) (wt %) MOF-5 769.90 C.sub.24H.sub.12O.sub.13Zn.sub.4 4000 1.35 (@100 bar, (@298K) 298K) MOF-200 1677.00 C.sub.90H.sub.62O.sub.17Zn.sub.4 4530 3.24 (@100 bar, (@77K, 298K) 80 bar)

(88) Within the tables, for respective MOF-5 and MOF-200, optimum tritium uptake may be achieved when the gravimetric capacity is maximized at the respective optimum temperature and pressure settings.
