Au@RhPd ultrathin nanowires are designed as a highly reactive and selective catalyst for the hydrogenation of phenol under ambient conditions. Au NWs modulate the electronic state of Rh atoms to enhance the adsorption of phenol and desorption of cyclohexanone. Pd works as a cocatalyst to activate H₂ to H* and spillover to Rh sites. This new catalyst shows a turnover frequency of up to 560 h⁻¹ for a wide spectrum of phenols with >80% selectivity toward cyclohexanones.

双金属效应促进Rh催化苯酚选择性加氢的活性

Au@RhPd 超薄纳米线被设计为在环境条件下用于苯酚氢化的高反应性和选择性催化剂。Au NWs 调节 Rh 原子的电子态以增强苯酚的吸附和环己酮的解吸。Pd 作为助催化剂将 H ₂激活为 H* 并溢出到 Rh 位点。这种新催化剂对广谱酚类的周转频率高达 560 h ^{-1 ，对环己酮的选择性大于 80%。}
