Abstract
Abstract Photocatalytic CO 2 conversion into solar fuels is a promising technology to alleviate CO 2 emissions and energy crises. The development of core‐shell structured photocatalysts brings many benefits to the photocatalytic CO 2 reduction process, such as high conversion efficiency, sufficient product selectivity, and endurable catalyst stability. Core‐shell nanostructured materials with excellent physicochemical features take an irreplaceable position in the field of photocatalytic CO 2 reduction. In this review, the recent development of core‐shell materials applied for photocatalytic reduction of CO 2 is introduced . First, the basic principle of photocatalytic CO 2 reduction is introduced. In detail, the classification and synthesis techniques of core‐shell catalysts are discussed. Furthermore, it is also emphasized that the excellent properties of the core‐shell structure can greatly improve the activity, selectivity, and stability in the process of photocatalytic CO 2 reduction. Hopefully, this paper can provide a favorable reference for the preparation of efficient photocatalysts for CO 2 reduction.
