Ru/g-C₃N₄ as an efficient catalyst for selective hydrogenation of aromatic diamines to alicyclic diamines.

ABSTRACT: A series of Ru/g-C₃N₄ materials with highly dispersed Ru were firstly prepared by an ultrasonic impregnation method using carbon nitride as a support. The catalysts were characterized by various techniques including BET and elemental analysis, ICP-AES, XPS, XRD, CO₂-TPD and TEM. The results demonstrated that Ru/g-C₃N₄ materials with a mesoporous structure and highly dispersed Ru were successfully prepared. The chemo-selective hydrogenation of p-phenylenediamine (PPDA) to 1,4-cyclohexanediamine (CHDA) over Ru/g-C₃N₄ as a model reaction was investigated in detail. PPDA conversion of 100% with a CHDA selectivity of more than 86% could be achieved under mild conditions. It can be inferred that the carbon nitrid
