Embodiment Construction

[0024] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0025] Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, the reaction chamber 6 is made of non-conductive material, and is preferably cast from PDMS. Of course, as an equivalent replacement, the reaction chamber 6 can also use other polymer materials in the field of microfluidics. A groove-shaped cavity is provided on the reaction chamber 6, and the cavity is sealed by the conductive glass 5 covered on the reaction chamber 6. The conductive glass 5 is preferably FTO conductive glass, and is fixedly connected to the reaction chamber 6. Together. The front part of the cavity of the reaction chamber body 6 is the reaction chamber 10, and the rear part is a cathode chamber 11 and an anode chamber 12 arranged side by side and communicated with each other. The front end of the cathode chamber 11 communicates with the rear end of the reaction chambe...

Abstract

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.

Description

technical field [0001] The invention belongs to the field of photocatalysis, and in particular relates to a photocatalytic hydrogen peroxide generation and photocatalytic fuel cell coupling system. Background technique [0002] Hydrogen peroxide (H 2 o 2 ), also known as hydrogen peroxide, is an important chemical product, and it is a clean and green oxidant. The standard electrode potential of hydrogen peroxide is relatively high (1.77V, 0.88V), and its oxidizing property is strong. It itself only contains two elements, hydrogen and oxygen, and the reaction only generates water (H 2 O) and oxygen (O 2 ), the product will not introduce any impurity ions into the reaction system, and has almost no effect on subsequent reactions, which is another major advantage of it. At present, the main method of producing hydrogen peroxide at home and abroad is the anthraquinone method (also known as the automatic oxidation method). This method is mature in technology, but the process...
