Monitoring the insertion of Pt into Cu2−xSe nanocrystals: a combined structural and chemical approach for the analysis of new ternary phases

The work explores the reactions between Cu$_{2−x}$Se premade nanoparticles and a Pt(ii) precursor, and confirms the formation of ternary CuPtSe phases with flexible stoichiometry and photocatalytic activity towards the hydrogen evolution reaction.
