| 英文摘要 | The electronic structure of supported metal catalysts efficiently affects molecule adsorption energy and reaction energy barriers, which are crucial to the activity of a catalyst. By preparing nanohybrids palladium nanoparticle supported on few-layer black phosphorus (Pd P/FL-BP) as a catalyst, the electron-deficient structure of palladium nanoparticles induced by black phosphorus modification is demonstrated. The as-synthesized Pd P/FL-BP exhibits much enhanced catalytic activity for the hydrogenation of 4-nitrophenol to 4-aminophenol, even higher than the best performances reported to date. Density functional theory calculations indicate that the high activity correlates with the electron-deficient Pd atoms, which help to reduce the adsorption energy of reactants and promote desorption of products from the electron-deficient active sites. |
