Water Splitting Hematite porous nanosheet arrays (NSAs) have been successfully synthesized through chemical vapor deposition of FeOCl NSAs followed by a subsequent annealing treatment. The obtained hematite electrode exhibits numerous advantages for application in photoelectrochemical water splitting, including superior light harvesting properties, an increased semiconductor/electrolyte interface for water oxidation, as well as fast charge transport properties. Remarkably, the porous NSA electrode is found to exhibit a much enhanced photocurrent compared with that of a planar electrode. Furthermore, the production method developed herein is very simple and continuous, which can pave the way for the large‐scale production of a highly efficient Fe‐based semiconductor.
