The endothermic reverse water‐gas shift reaction (rWGS) for direct CO 2 hydrogenation to CO is an attractive approach to carbon utilization. However, direct CO 2 hydrogenation with molecular catalysts generally gives formic acid instead of CO as a result of the selectivity of CO 2 insertion into M−H bonds. Based on the photochemical inversion of this selectivity, several synthetic pathways are presented for CO selective CO 2 reduction with a nickel pincer platform including the first example of a photodriven rWGS cycle at ambient conditions.
