Title : Synergistic Catalysis of nano-metal and semiconductor (metal oxides) molecular/ atomic-layer film coated on the support of Novel Hybird complex nano-structured Pt Catalyst prepared by photochemical route

Abstract:

Herein, we report a novel strategy, which combine nano-metal with semiconductor (metal oxides) atom layer film coated on the support, to fabricate Novel Hybird Complex Nano-structured Pt/@-MeOx/SBA-15 Catalyst prepared by photochemical route. This Hybird Complex Nano-structured Pt/@-MeOx/SBA-15 Catalyst is a novel Hybird nano-structured catalysts, which nano-metal were anchored on the semiconductor (metal oxides) atom -layer film coated on the support.

The novel Hybird complex nano-structured Pt Catalyst exhibited remarkable catalytic activity in the selective hydrogenation of benzaldehyde, conversion exceeding 99.9% was achieved with >99% selectivity. No decay in the activity was observed by 12 cycles. for the Chemoselective hydrogenation of nitro compounds by 0.1wt% Pt/@-MeOx/SBA-15 Catalyst, Conversion achieved up to more than 99% with the selectivity of more than 99% .For the selective hydrogenation of p-chloronitrobenzene, it also obtained high selectivity(>99%) at complete conversion, the catalyst yields a TOF of 57588 h-1, about 2 orders of magnitude higher than that of the traditional Pt catalysts and 11.5-fold higher than the best result reported in the literature.  

More importantly, the Novel Hybird Complex Nano-structured Pt Catalyst exhibited the Synergistic Catalysis of nano-metal and semiconductor (metal oxides) atom-layer film coated on the support for the Chemoselective hydrogenation of nitro compounds by Pt/@-MeOx/SBA-15 catalysts and for the selective hydrogenation.The superior performance can be attributed to the Synergistic Catalysis of nano-metal and semiconductor (metal oxides) atom-layer film coated on the support and the unique properties of hybird nano-structure.
