Interfacial engineering regulating the electronic structure of cobalt active sites in hollow Co3S4/In2S3 for enhanced photothermal catalytic cycloaddition of diluted CO2
研究概述
构筑中空Co3S4/In2S3异质结，以光捕获空腔增强吸光，利用界面内建电场促进In2S3向Co3S4电子转移，调节Co位点对CO2和环氧化物的吸附活化。光热协同条件下，15 vol%稀释CO2仍实现91%的目标环状碳酸酯收率，计算表明限速步骤能垒降低。
