Recent advances in core–shell metal organic frame-based photocatalysts for solar energy conversion

Photocatalysis is a prospective technology that directly converts solar energy into chemical energy under mild reaction conditions. The development of photocatalysts with high-performance is the core faced by photocatalytic technology. Recently, core–shell metal organic frameworks (MOFs), which are composed of MOFs as the core or shell with other materials, have attracted extensive attention in photocatalytic applications. The core–shell MOF structure results in huge advantages, such as large specific surface areas, adequate exposed surface-active sites, and low photogenerated electron-hole recombination. This review briefly summarizes the common synthesis strategies of core–shell MOF-based materials, including one-pot synthesis, in-situ synthesis, self-template method and layer-by-layer assembly method. In this review, the research progress of [email protected], [email protected] and core–shell-like MOF photocatalysts in environmental remediation and energy production is also summarized. Finally, the perspectives of core–shell MOF-based photocatalysts are also proposed.
