Influence of nitrogen functional groups in carbon-based support anchoring Pt nanoclusters and single atoms for efficient ammonia borane hydrolysis

Abstract

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