AI Article Synopsis
- The reverse water-gas shift reaction (rWGS) is a promising method for converting carbon dioxide into carbon monoxide using hydrogen, but traditional molecular catalysts often produce formic acid instead.
- Researchers have proposed new synthetic pathways using a nickel pincer catalyst to selectively reduce CO to CO, focusing on modifying the reaction's selectivity.
- A novel photodriven rWGS cycle has been demonstrated, operating effectively under ambient conditions, showcasing the potential for improved carbon utilization.
Article Abstract
The endothermic reverse water-gas shift reaction (rWGS) for direct CO hydrogenation to CO is an attractive approach to carbon utilization. However, direct CO hydrogenation with molecular catalysts generally gives formic acid instead of CO as a result of the selectivity of CO insertion into M-H bonds. Based on the photochemical inversion of this selectivity, several synthetic pathways are presented for CO selective CO reduction with a nickel pincer platform including the first example of a photodriven rWGS cycle at ambient conditions.
