Photocatalytic hydrogen production of Melon/Azodiphenylamine polymers

Hydrogen is one of the most attractive energy sources at present for its excellent properties, such as high energy density, clean and non-pollution energy. Photocatalytic hydrogen evolution is one of the ideal strategies to obtain hydrogen energy. This work aimed to improve the visible-light absorption ability of the structure similar to g-C3N4 by anchoring azo groups into the structure. By this, the photocatalytic hydrogen production rate of the resulting product was improved apparently. We use melamine as starting material to prepare Melon, which was further reacted with KOH, PCl5 and 4, 4-Diaminoazobenzene to get the target Melon/4, 4-Diaminoazobenzene polymer. The condition influencing on the reaction was investigated, such as reaction temperature, the ratio of reactants and concentration of KOH solution. The structure of the as-synthesized polymer was determined IR, XRD, SEM, TGA and EIS. At the same time, its photocatalytic property was investigated.
