## TL;DR

Adding nitrogen to carbon supports improves platinum catalysts for efficient hydrogen release from ammonia borane.

## Contribution

Nitrogen in carbon nitride enhances platinum's electronic structure and catalytic performance for ammonia borane hydrolysis.

## Key findings

- Pt nanoclusters and single atoms were formed on carbon nitride supports.
- Nitrogen species improved Pt's electronic and topological structure.
- Pt/CNx catalysts showed enhanced hydrogen evolution from ammonia borane.

## Abstract

A 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.

The N species on CNx modified the electronic and topological structure of Pt, improving the catalytic properties of the Pt/CNx catalyst in evolving hydrogen from NH3BH3.
