摘要
In this work, we report an efficient strategy for controllable decoration of CNTs supported Pt catalysts with NiO by atomic layer depositon (ALD). The number of NiO ALD cycle has a significant effect on the catalytic activity and selectivity of Pt/CNTs catalyst for the tandem hydrogenation of nitro compounds to aromatic amines. Suitable amount of NiO decoration (e.g., 10-cycle NiO) could simultaneously improve the activity and selectivity of Pt/CNTs catalyst. The ALD deposited NiO species contact with Pt nanoparticles, providing unique surface structure and targeted Pt electronic properties for chemoselective tandem hydrogenation of nitro compounds.
