NOVELTY - A heterojunction photovoltaic electrode preparing method involves selecting gold-cadmium sulfide/reduced graphene oxide/ titanium dioxide heterojunction photovoltaic pole, manufacturing fluorine-doped tin oxide substrate by using double titanium dioxide nanorod, coating with graphene oxide and performing sintering to obtain reduced graphene oxide/ titanium dioxide heterojunction, followed by performing gold deposition process and performing cadmium sulfide deposition process to obtain gold-cadmium sulfide/reduced graphene oxide/ titanium dioxide heterojunction photovoltaic pole. USE - Method for preparing heterojunction photovoltaic electrode for working electrode of hydrolysis reaction (claimed). ADVANTAGE - The method enables preparing heterojunction photovoltaic electrode with better chemical stability and better photoelectrochemical performance in a simple, reproducible, cost-effective and eco-friendly manner. DETAILED DESCRIPTION - A heterojunction photovoltaic electrode preparing method involves selecting gold-cadmium sulfide/reduced graphene oxide/ titanium dioxide heterojunction photovoltaic pole, manufacturing fluorine-doped tin oxide substrate by using double titanium dioxide nanorod, coating with graphene oxide by using spin-coating process and performing sintering under nitrogen protection to obtain reduced graphene oxide/ titanium dioxide heterojunction. The obtained heterojunction is performed gold deposition process to obtain gold/reduced graphene oxide/ titanium dioxide heterojunction, followed by performing cadmium sulfide deposition process to obtain gold-cadmium sulfide/reduced graphene oxide/ titanium dioxide heterojunction photovoltaic pole.
