摘要：Supported Pt nanocatalysts with controlled particle size and size distribution were prepared by immobilizing Pt colloids on different iron oxide supports (gamma-Fe2O3, Fe3O4, Fe2O3) via physical adsorption. These catalysts were used to catalyze the liquid phase hydrogenation of o-chloronitrobenzene (o-CNB) to o-chloroaniline (o-CAN) under mild reaction conditions (298 K, 0.1 MPa). The Pt/gamma-Fe2O3 exhibited higher catalytic selectivity and activity than other similar works (selectivity = 99.9%, activity = 0.20 mol(o-CNB)/(mol(Pt) s)). The stability of the Pt/gamma-Fe2O3 was investigated, and the result showed that higher drying temperature could increase the stability of the catalyst.
