英文摘要The metal-support interaction (MSI) in heterogeneous catalysts plays a crucial role in reforming reaction to produce renewable hydrogen, but conventional objects are limited to single metal and support. Herein, we report a type of RhNi/TiO2 catalysts with tunable RhNi-TiO2 strong bimetal-support interaction (SBMSI) derived from structure topological transformation of RhNiTi-layered double hydroxides (RhNiTi-LDHs) precursors. The resulting 0.5RhNi/TiO2 catalyst (with 0.5 wt.% Rh) exhibits extraordinary catalytic performance toward ethanol steam reforming (ESR) reaction with a H-2 yield of 61.7%, a H-2 production rate of 12.2 L h(-1) g(cat)(-1) and a high operational stability (300 h), which is preponderant to the state-of-the-art catalysts. By virtue of synergistic catalysis of multifunctional interface structure (Rh-Ni delta--O-v-Ti3+; O-v denotes oxygen vacancy), the generation of formate intermediate (the rate-determining step in ESR reaction) from steam reforming of CO and CHx is significantly promoted on 0.5RhNi/TiO2 catalyst, accounting for its ultra-high H-2 production. Ethanol steam reforming (ESR) reaction is an environmentally benign and sustainable route for H-2 production. Herein, the authors demonstrate a conceptional strategy for rational design and preparation of highly-efficient catalyst toward ESR via an RhNi-TiO2 strong bimetal-support interaction.
