Influence of Au Nanoparticle Concentration on H2 Production over SrTiO3 Perovskite: Role of Metal–Semiconductor Charge Separation
The development of efficient photocatalysts for hydrogen production is a key challenge for sustainable energy technologies. In this study, strontium titanate (SrTiO3) was synthesized via a citrate-assisted sol-gel method and subsequently modified by deposition-precipitation using nominal HAuCl4 precursor concentrations...
