The invention is a water purification system without use of chemical substances. The essential parts of the system are: a chamber with inlet and outlet for flowing incoming and outgoing air into and out of the chamber; UV radiation bulb(s)/lamp(s); pair(s) of magnetic rings; and a skeleton configured for occupying center volume of the chamber from top to bottom around central longitudinal axis of the chamber. The skeleton has inner space for accommodating the UV radiation bulb(s)/lamp(s) and at least one pair of holding elements for holding the pair(s) of magnetic rings around the UV radiation bulb(s)/lamp(s). The purification system comprises concentric configuration to minimally perturb profile and distribution of the incoming and outgoing air, the pair(s) of magnetic rings are positioned in parallel relative each other and configured to induce maximal concentric magnetic flux field on molecules of the flowing incoming and outgoing air.

A catalyst for synthesizing hydrogen peroxide is provided. The catalyst includes first material capable of dissociating hydrogen molecules; and second material capable of suppressing dissociation of oxygen molecules, where one or more interfaces are formed between the first material and the second material. The catalyst can be used as an alternative to the expensive palladium catalysts. In particular, the catalyst can be used for the direct synthesis of hydrogen peroxide.

A system and method for performing plasma reactions creating a plasma area in a gas adjacent to a liquid. An embodiment of the plasma reactor includes a housing with an internal reaction chamber, first and second inlet paths to the reaction chamber, and electrodes for producing an electric field. The system may optionally further include a pre-ionization electrode and pre-ionization electric field for pre-ionizing a feed gas prior to entry into a reaction chamber. The reactor uses plasma to ionize gas adjacent with the liquid. The ionized gas reacts with the liquid to form an effluent. Exemplary uses of the plasma reactor include ionic injection, gas dissociation, liquid re-formation, and liquid dissociation.

Catalysts for selective production of hydrogen peroxide and methods of making and using thereof have been developed. The catalysts include an alloyed or doped metal oxide which permits tuning of the catalytic properties of the catalysts for selection of a desired pathway to a product, such as hydrogen peroxide. The catalysts may be incorporated into electrochemical or photochemical devices.

A catalyst and a catalyst composition, a method for preparing thereof, and a method for synthesizing of hydrogen peroxide using them are provided. The catalyst and the catalyst composition contains: an alloy of two elements, wherein the elements are Pt (Platinum) and Ni (Nickel). The present disclosure enables (a) replacing a high-priced palladium (Pd) catalyst with a new catalyst, (b) providing a high-active catalyst which catalyzes the direct synthesis reaction of the hydrogen peroxide.
