Also described is a process for making a graphene paper from the graphene pellet comprising applying a compression force to the graphene pellet sufficient to compress the pellet. Also described is a method for forming a graphene pellet composite useful as an electrode.

The present invention is a method of implementing Water Disinfection System employing a Functional Mixture, copper foam catalyst, continuous flow, UV radiation, and optical receiver pipe in order to inactivate broader range of microbial contaminants in drinking water, both for emergency purification kits and larger filtration systems. The Functional Mixture is formed when the portland cement (CaO—SiO.sub.2—Al.sub.2O.sub.3) and silicon dioxide (SiO.sub.2) combination is applied to the amalgamation of porous copper foam (Cu-Foam) and silver nitrate (AgNO.sub.3) particles, which react through the silver tree reaction (Cu+2AgNO.sub.3.fwdarw.2Ag+Cu(NO.sub.3).sub.2) after spraying over a perforated mask. The high porosity Functional Mixture is placed in UV transmissive receiver pipe with optical properties. These configurations improve the coverage, efficiency, and effectiveness of reducing broader range of pathogenic microbes in water disinfection systems over prior art. Further optimizations are available for broader range of solar lighting conditions and water flow rates.

A process for use of composite catalysts for oxidation of amines during synthesis of energetic compounds. This method overcomes the safety concerns associated with dangerous reaction conditions for these energetic materials. The process requires exposing phthalocyanine conjugated to an inorganic substrate to the precursor reactant and activating the composite material to light and oxygen to covert amine groups into oxidized nitrogen species.
