摘要：
The CdS/CaTiO3 cubic core-shell composite is synthesized via a hydrothermal-chemical method. The CdS/CaTiO3 cubic core-shell composite (CdS/CTO-2) exhibits remarkable photocatalytic HER activity (-1025.27 mmol$g �1 h-1) and photodegradation enhancement than that of single CaTiO3 (-21 folds of HER,-19 folds of photodegradation) and single CdS (-15 folds of HER,-15 folds of photodegradation), and a decent stability. There, CdS/CaTiO3 composite with appropriate potential gradient and CdS with better visible light response can improve carrier efficiency, including increasing carrier transportation, prolonging lifetime and decreasing recombination. Additionally, cubic core-shell microstructure can increase active sites, while maintaining photocatalytic stability.& COPY; 2023 Hydrogen Energy Publications LLC. Published by Elsevier Ltd.
