biostudies-literatureUnknown15(13)Nan FSemiconductor photoelectrochemical (PEC) technology, capable of generating hydrogen energy from water and solar energy, has emerged as a promising solution to address environmental and energy challenges. Rhodium-doped strontium titanate (Rh doped SrTiO₃, RST) is regarded as a highly promising photocathode material for PEC systems. Nevertheless, the PEC performance of RST is hindered by inefficient carrier separation and poor charge transfer properties. In this paper, a hybrid RST/g-C₃N₄ heterojunction sample was prepared by a simple method. The pure RST sample possesses the ability to absorb visible light and exhibit p-type semiconductor characteristics with a negative photocurrent value of -6.2 μA cm^-2, and can be used as a photocathode materialRSC advances9627-9635https://www.ebi.ac.uk/biostudies/studies/S-EPMC11955826biostudies-literatureConstruction of a Rh-doped SrTiO<sub>3</sub>/g-C<sub>3</sub>N<sub>4</sub> p-n heterojunction for enhanced photoelectrochemical performance.PMC11955826Li HZhou LWang SNan FLin YChen SFan BfalseConstruction of a Rh-doped SrTiO<sub>3</sub>/g-C<sub>3</sub>N<sub>4</sub> p-n heterojunction for enhanced photoelectrochemical performance.Semiconductor photoelectrochemical (PEC) technology, capable of generating hydrogen energy from water and solar energy, has emerged as a promising solution to address environmental and energy challenges.
