Engineering Stable Cu-Doped SrTiO₃ Perovskites for Enhanced Photocatalytic CO₂ Reduction.

ABSTRACT: Photocatalytic CO₂ reduction presents a sustainable pathway for renewable energy generation while addressing critical environmental challenges. Strontium titanate (SrTiO₃) has emerged as a highly efficient wide-bandgap semiconductor photocatalyst for CO₂ reduction. In this study, we investigate copper-doped strontium titanate (Cu/STO), synthesized via a hydrothermal method, which exhibits a well-defined cubic-like structure. The work focuses on optimizing the CO₂ reduction process by systematically varying the pH of the reaction medium using HCl and NaOH. Our findings reveal that pH significantly influences product selectivity, with a notable shift from methane (CH₄) to carbon monoxide (CO) production, highlighting the role of pH in mo
