Atomically precise heterostrucutures present chemically interesting active sites for catalysis but are often expensive and/or challenging to synthesize. In this article, we report a synthetic strategy to conformally coating Cu atoms onto the surface of Pd/HyWO3-x by anchoring Cu(I)OtBu to the Brønsted acidic protons of the bronze. It was observed that just 0.2 at.% of Cu was able to increase the catalytic performance of CO2 hydrogenation to CO by 500%. This metal anchoring method enables atom precise modification of the surfaces of metal oxide nanomaterials for catalytic applications, circumventing the need for complex and expensive atomic layer deposition processes.
