Abstract：

Using　solar-powered　photocatalytic　technology　to　convert　CO2　to　high　value-added　chemical　products　is　a　hopeful　strategy　to　solve　the　energy　and　environmental　problems　of　modern　society.　Herein,　a　direct　Z-scheme　InVO4/La2Ti2O7　photocatalyst　is　successfully　synthesized,　achieving　efficient　and　selective　CO2　reduction　to　CO　with　nearly　100　%　CO　selectivity,　and　the　CO　yield　is　4.2　and　3.3　times　that　of　individual　La2Ti2O7　and　InVO4,　respectively.　The　significantly　enhanced　photocatalytic　performance　is　owing　to　the　formation　of　Z-scheme　charge　transfer　mechanism,　fostering　the　spatial　separation　and　transfer　of　photogenerated　carriers.　This　work　provides　new　perspectives　for　the　rational　design　of　La2Ti2O7-based　photocatalytic　materials　toward　efficient　and　selective　CO2　reduction　to　CO.　©　2022　Elsevier　B.V.
