Abstract

A Pt(II) precursor was impregnated onto graphite (C) and carbon nitride (CN_x), successfully forming subnanometric Pt clusters and single atoms. The N species on CN_x modified the electronic and topological structure of the metal, improving the catalytic properties of the Pt/CN_x catalyst in evolving hydrogen from NH₃BH₃. This was rationalised by combining HR-TEM and XPS characterisation with DFT computational analysis.
