A novel preparation method for bimetallic nickel-indium alloy catalysts supported on amorphous alumina (Ni-In(x)/AA; x = Ni/In molar ratio) catalysts has been developed and evaluated for the highly selective hydrogenation of biomass-derived furfural. Ni-In(x)/AA catalysts were obtained via the hydrothermal treatment of Raney® nickel supported on aluminium hydroxide (R-Ni/AlOH) and an InCl₂·H₂O solution in an ethanol/H₂O mixture at 423 K for 2 h, followed by reduction with H₂ at 573–873 K for 1.5 h. The formation of Ni-In alloy phases such as Ni₃In₂, Ni₃In, Ni₂In, and NiIn in Ni-In(2.0)/AA was clearly observed after reduction with H₂ at 873 K for 1.5 h. Ni-In(2.0)/AA contained a Ni₂In alloy as the major phase, which exhibited the best catalytic performance for the selective hydrogenation of furfural into furfuryl alcohol and was stable for at least five consecutive reaction runs.

已经开发了一种新颖的制备负载在无定形氧化铝上的双金属镍-铟合金催化剂的方法（Ni-In（x）/ AA；x  = Ni / In摩尔比），并用于生物质衍生糠醛的高选择性加氢。Ni-In（x）/ AA催化剂是通过在423 K下对氢氧化铝（R-Ni / AlOH）和InCl ₂ ·H ₂ O溶液在乙醇/ H ₂ O混合物中的镍负载的阮内镍进行水热处理而获得的持续2 h，然后在573–873 K下用H ₂还原1.5 h。Ni ₃ In ₂，Ni ₃ In，Ni ₂等Ni-In合金相的形成在873 K下用H ₂还原1.5 h后，可以清楚地观察到In和NiIn的Ni-In（2.0）/ AA中。Ni-In（2.0）/ AA以Ni ₂ In合金为主相，对糠醛选择性加氢成糠醇表现出最好的催化性能，并且至少连续5次反应稳定。
