Irradiating a film of a thiophene polymer that is a pure organic compound with light allows the thiophene polymer film to act as a light absorber and catalyst that produces hydrogen peroxide from water and water-dissolved air (oxygen) at extremely high efficiency, and this film can work in alkaline water in which a film of a general-purpose inexpensive water-oxidizing catalyst, which is used as a counter electrode, is active. Provided is an environmentally compatible and simple method for producing hydrogen peroxide at extremely high efficiency, including combining a film of a catalyst for light absorption and oxygen reduction that consists of a thiophene polymer with a catalyst for water oxidation, immersing the combination in alkaline water, and irradiating the light-absorbing oxygen reduction catalyst film with light.

A photothermal catalytic method for production of hydrogen peroxide without a sacrificial reagent on the basis of a porphyrin-based supermolecule is provided. The method includes the following steps: uniformly mixing a porphyrin-based supermolecule photocatalyst with a concentration of 0.3-1.5 g/L with ultrapure water, conducting irradiation with a visible light for a period of time under stirring at a temperature of 40-80° C. and an O.sub.2 flow rate of 50-150 mL/min, and then filtering and concentrating a reaction liquid to obtain an aqueous hydrogen peroxide solution with a high concentration. According to the new photothermal catalytic method for preparing the hydrogen peroxide provided in the present disclosure, no organic solvent (such as ethanol, isopropanol and benzyl alcohol) is used as a sacrificial reagent, and the method is environmentally friendly and free of pollution. O.sub.2 is used as an oxygen source, sunlight is used as an energy source, and the method is low in energy consumption and high in safety (compared with an industrial anthraquinone method for synthesizing hydrogen peroxide). The method is simple in operation, mild in reaction conditions and high in production of the hydrogen peroxide.

A universal chemical processor (UCP) including a reactor vessel with a main chamber, comprises inlets for feedstock, a fluidizing medium and reactants. The UCP further includes a reactive X-ray chemical processor (RXCP) having a large area hollow cylindrical cold cathode in the main chamber, a grid positioned concentrically with respect to the cathode, and an anode positioned concentrically with respect to the cathode and grid. In operation, when activated, the cathode of the RXCP emits electrodes onto the anode, which then emits X-rays into a radiation zone within the main chamber capable of ionizing feedstock and reactants, inducing chemical reactions, and sterilizing and decomposing organic materials within the radiation zone, and wherein, a fluidized bed is supported in the main chamber when the fluidizing medium and feedstock are supplied. The RXCP and the fluidized bed portions can be operated separately or in conjunction to achieve unanticipated results.
