Abstract

In this study, a novel photoelectrochemical reactor for hydrogen and clean water production is designed, constructed, and experimentally investigated. TiO₂ photocatalyst is used in a photoelectrochemical (PEC) reactor, which cleans the water via Fenton-like process and produces hydrogen. A novel dual anode structure is used in the experiments. The TiO₂ nanoparticle deposited photoanode induces electro currents for hydrogen production and produces hydroxyl ions, which assist the removal of chemical oxygen demand (COD) process. The second anode is a stainless-steel plate, which is used as a sacrificial anode to electrogenerated iron ions for the Fenton process. It is aimed to reduce the anode cell half potential and energy consumption by replacing oxygen evaluation with the iron oxidation process. The overall energy and exergy efficiencies of the system are 81% and 80% respectively. After 40 minutes of the operation time of the PEC reactor under 2.3V and 60°C of cell potential and temperature, the reactor produces 22.6 mg of hydrogen and removes 87% of the COD.
