Hierarchical Co0.85Se‐CdSe/MoSe2/CdSe Sandwich‐Like Heterostructured Cages for Efficient Photocatalytic CO2 Reduction

and 90.14% selectivity, which are much higher than those of other control samples including single-component catalysts and binary hybrid catalysts. This study provides a promising way for the design and fabrication of high-efficiency photocatalysts.
