Reaction-driven selective CO<sub>2</sub>hydrogenation to formic acid on Pd(111)
Hong Zhang, Xuelong Wang, Ping Liu
Abstract
a multi-step process involving the carboxyl intermediate. The high formic acid selectivity is associated with surface hydrogen species on Pd(111), which not only acts as a hydrogen reservoir to facilitate the hydrogenation steps, but also enables the formation of confined vacancy sites to facilitate the production and removal of formic acid. Our study highlights the importance of reactive environments, which can transform the surface structures and thus tune the activity/selectivity of catalysts.
