Proton Source Selective Semi-Hydrogenation of Alkynes: A Water-Powered Selective Photocatalyst Based on Nickel Single-Atoms on Poly(Heptazine Imide)

The dataset includes the complete set of figures and raw data associated with the article, encompassing: (i) physicochemical characterization of the Ni single-atom catalysts stabilized on poly(heptazine imide) (PHI), (ii) experimental data from the photocatalytic semi-hydrogenation of phenylacetylene to styrene using water as the proton source, (iii) detailed descriptions and parameters of the reaction system employed in the photocatalytic experiments, and (iv) full methodologies for catalyst synthesis, material processing, and reaction procedures.

These files collectively support all results and discussions presented in the manuscript. The dataset will be made openly available upon publication.
