The invention discloses a photocatalytic
hydrogen peroxide generation and photocatalytic fuel
cell coupling system. A groove-shaped cavity is formed in a reaction cavity body and is sealed by conductive glass, the front portion of the cavity is a
reaction chamber, the rear portion is provided with a
cathode chamber and an
anode chamber arranged side by side and communicated mutually, a photocatalyst layer is arranged in the
reaction chamber, a
cathode catalyst layer is arranged in the
cathode chamber, an
anode photocatalyst layer is arranged in the
anode chamber, and the photocatalyst layer, the
cathode catalyst layer and the anode photocatalyst layer are supported on the conductive glass. The
system integrates photocatalytic
hydrogen peroxide generation and simultaneous power generation of
organic matter from photocatalytic fuel
cell disposal, is simple in structure and low in cost and has the advantages of being free of membranes, large in specific surface area, high in
mass transfer efficiency, accurate in flow control, short in
contact time, easy to enlarge, uniform in lighting, small in
optical path loss and the like, and the performance is effectively improved. The
organic matter in water can be utilized to generate power, environmental
pollution can be controlled, and meanwhile
electric energy can be also obtained.
