The invention relates to the technical field of new energy test equipment, in particular to a detection system for hydrogen and oxygen production through photoelectrocatalytic water decomposition and a use method of the detection system. The system and method are used for solving the problems of obtaining an optimal mode with the highest hydrogen evolution efficiency for an anode, a cathode, an electrolyte and a photocatalyst, mastering data in an electrolytic reaction process and effectively analyzing various electrolytic reaction materials and hydrogen and oxygen separation speed. The detection system is a container composed of a first container, a second container and a middle connecting pipe for tests. A photocatalytic electrolytic reaction is formed by matching a direct-current power supply with a catalytic light source. A gravity detection unit independently records the weight of the first container and the weight of the second container, oxygen evolution and hydrogen evolution are generated along with continuous proceeding of the reaction, gas is collected by a guide unit and guided to an oxygen detection chamber and a hydrogen detection chamber respectively, the total amount of the electrolyte is metered at the moment, and each time is stably recorded by a recording unit. The process is repeated.

Problems solved by technology

[0004] The anode materials are mainly metal alloy materials or noble metal oxides, such as RuO2 and RhO2, which have good oxygen evolution catalytic activity, and the price of metal alloy materials is low, and they have good corrosion resistance in alkaline electrolytes , but the potential is not high during the oxygen evolution process, and the efficiency is not good; noble metal oxides are more suitable for acidic media, and their corrosion resistance in alkaline media is poor and expensive; even if the requirements for anode materials are high, the current research There are still technological breakthroughs, and new anode substitutes such as coated electrodes have been formed; for this reason, the treatment methods, processes and new materials that can improve the oxygen evolution activity of anode materials such as surface decoration, active layers, and composites continue to the emergence of
