About this collection
This Editor’s collection, guest edited by Editorial Board member Tong-Bu Lu, highlights the recent papers in CrystEngComm which are related to Metal Organic Framework (MOFs) based catalysts for water splitting and CO2 reduction.
Recently, water splitting and CO2 reduction have drawn much interest due to the global energy shortage and climate deterioration caused by greenhouse gas emissions. MOFs possess defined structures and unsaturated metal coordination catalytic sites, so it is beneficial to understand the structure–catalytic activity relationship. In addition, the catalytic activity of MOFs can be optimized by tuning the structures of MOFs, as well as the post-decorating of molecular/nanoparticles within their channels or frameworks. However, the stability of MOFs after catalysis must be checked to confirm they act as the actual catalyst, as under strongly acidic or basic catalytic conditions, MOFs may decompose to release metal ions or metal oxides as the catalytic species.
