Low-nuclearity CuZn ensembles on ZnZrO catalyze methanol synthesis from CO.

Metal promotion could unlock high performance in zinc-zirconium catalysts, ZnZrO, for CO hydrogenation to methanol. Still, with most efforts devoted to costly palladium, the optimal metal choice and necessary atomic-level architecture remain unclear. Herein, we investigate the promotion of ZnZrO catalysts with small amounts (0.
