We successfully constructed an ultrathin Ti3C2Tx supported Pt nanocluster catalyst for highly selective and efficient hydrogenation of p-chloronitrobenzene (p-CNB) to p-chloroaniline (p-CAN) under mild conditions (30 °C, 0.1 MPa H2). The Pt/Ti3C2Tx displayed a very high conversion (>99%) selectivity (>99%). In addition, higher reaction rate (41 mol h–1 g–1) was obtained in comparison with the previously reported catalysts. excellent catalytic activity attributed strong metal–support interactions between nanoclusters support, which electrons were transferred from sites, affording electron density active sites. Moreover, electrostatic repulsion C–Cl moiety sites inhibited dechlorination process. also exhibited performance substrate scope (reducible heterocyclics such as pyridine phthalimide), stability (10th cycles, >99% 98%), gram-scale (99% yield, 1.89 g). This work will promote research constructing noble metal-based catalysts halogenated nitroarenes.
