We developed a facile strategy to synthesize series of water-soluble Pt, PtxNi1-x (0 < x 1), and Ni nanocrystals. The octahedral, truncated cubic shapes were uniformly controlled by varying crystal growth inhibition agents such as benzoic acid, aniline, carbon monoxide. compositions the nanocrystals effectively choice ratios between Pt precursors. In preliminary study probe their structure–activity dependence, we found that shapes, compositions, capping strongly influence catalyst performances in three model heterogeneous hydrogenation reactions.
