Abstract

An Fe-based oxyhydroxide catalyst was developed for CO2 photoreduction into formic acid. As reported by Kazuhiko Maeda et al. in their Communication (DOI: 10.1002/anie.202204948), α-iron(III) oxyhydroxide, which is an easily available soil mineral and is loaded onto an alumina support, serves as a recyclable catalyst for the C-O2 reduction reaction, showing 80–90 % selectivity and an apparent quantum yield of 4.3 % at 460 nm with the aid of a ruthenium(II) photosensitizer and an electron donor.
