探索不太常见的金属-非金属纳米合金的新型催化作用在有机合成中具有重要意义。在此，我们报道了一种二氧化钛负载的磷化镍纳米合金(纳米Ni2P/二氧化钛)，它对亚砜的脱氧具有很高的催化活性。纳米Ni2P/TiO2光催化剂在1bar的氢气压力下将各种亚硫化物脱氧为硫化物，是第一个在常压氢气压力下用于亚砜脱氧的非贵金属催化剂。光谱分析表明，这种高活性是由于纳米Ni2P和二氧化钛的协同催化作用。
Exploring novel catalysis by less common, metal-non-metal nanoalloys is of great interest in organic synthesis. We herein report a titanium-dioxide-supported nickel phosphide nanoalloy (nano-Ni2P/TiO2) that exhibits high catalytic activity for the deoxygenation of sulfoxides. nano-Ni2P/TiO2 deoxygenated various sulfoxides to sulfides under 1 bar of H-2, representing the first non-noble metal catalyst for sulfoxide deoxygenation under ambient H-2 pressure. Spectroscopic analyses revealed that this high activity is due to cooperative catalysis by nano-Ni2P and TiO2.
