Chlorine plays an essential role in various industries, such as wastewater treatment, disinfection, plastics, and pharmaceuticals, contributing to a significant global demand. Traditional methods of chlorine production, including chemical reactions involving manganese dioxide, potassium chlorate, permanganate, well the electrolysis saturated salt solutions, are associated with safety efficiency concerns. This study introduces novel approach for photoelectrocatalytic production gas through oxidation chloride ions solutions using dual semiconductor photoelectrode system composed TiO2 Cu2O. By harnessing solar energy, this enables concurrent, safe, efficient both hydrogen gases. The is employed while Cu2O used generation. mimics process electrolytic seawater electrolysis, offering promising alternative conventional methods. Through linear sweep voltammetry, current–time tests, electrochemical impedance spectroscopy, we demonstrate effectiveness approach, supported by detailed analysis energy band structure. Additionally, material’s characteristics were verified X-ray diffraction (XRD) scanning electron microscopy (SEM). work not only provides safer more method but also highlights potential solar-powered photoelectrocatalysis large-scale applications. These findings point toward sustainable environmentally friendly direction under simulated conditions, implications renewable energy-driven industrial processes.
