Abstract

Cu nanoassemblies formed transiently during reaction from size-selected subnanometer Cu₄ clusters supported on amorphous OH-terminated alumina convert CO₂ into methanol and hydrocarbons under near-atmospheric pressure at rates considerably higher than those of individually standing Cu₄ clusters. An in situ characterization reveals that the clusters self-assemble into 2D nanoassemblies at higher temperatures which then disintegrate upon cooling down to room temperature. DFT calculations postulate a formation mechanism of these nanoassemblies by hydrogen-bond bridges between the clusters and H₂O molecules, which keep the building blocks together while preventing their coalescence.
