In this article, Pt-SnxOy hybrid nanoparticles encaged in porous silica nanospheres (Pt-SnxOy@PSNs) were prepared by using 1-dodecanethiol (C12-SH) as a coordination agent to confine Pt and Sn ions microemulsion system, which is formed cetyltrimethylammonium bromide (CTAB) C12-SH co-surfactants water. Compared with Pt@PSNs, when different molar ratios of SnxOy introduced into Pt@PSNs form Pt-SnxOy@PSNs, the catalytic efficiency 4-nitrophenol (4-NP) reduction NaBH4 can be significantly enhanced. At 4-NP/Pt 150/1, 4-NP conversion reached 100% over Pt-SnxOy@PSNs Pt/Sn 1/0.75 8 min. This performance showed slight decrease after six reaction cycles. enhanced ascribed synergistic effect between SnxOy, protection nanostructures effectively improve stability catalyst.
