A Bismuth-Based Metal-Organic Framework as an Efficient Visible-Light-Driven Photocatalyst

A visible‐light‐responsive bismuth‐based metal–organic framework (Bi‐mna) is demonstrated to show good photoelectric and photocatalytic properties. Combining experimental and theoretical results, a ligand‐to‐ligand charge transfer (LLCT) process is found to be responsible for the high performance, which gives rise to a longer lifetime of photogenerated charge carriers. Our results suggest that bismuth‐based MOFs could be promising candidates for the development of efficient visible‐light photocatalysts. A visible‐light‐responsive bismuth‐based metal–organic framework (Bi‐mna) is shown to exhibit good photoelectric and photocatalytic properties. Combined with the experimental and theoretical results (see electron localization function plot), a ligand‐to‐ligand charge transfer (LLCT) process is found to be responsible for the high performance. This process gives rise to a longer lifetime of the photogenerated charge carriers.
