Abstract

We developed a semiconductor photocatalyst, Pd–Pt alloy nanoparticle-loaded, Al-doped SrTiO₃ (PdPt/STO:Al), for photoreduction of unsaturated carboxylic acids. Due to the cooperative STO:Al surface and Pd–Pt alloy nanoparticles, the catalyst dispersed in water provided highly redox-selective photoreduction against oxidative degradation of starting materials/products and against reductive evolution of H₂, where minimal glycolic acid worked as an efficient electron-donating fuel.
