文摘

Ag@Pt/sepiolite catalysts were prepared by a successive reduction method. Core-shell Ag@Pt nanoparticles were highly dispersed on sepiolite nanofibers. The Ag@Pt core-shell structure enhanced the reduction of nitrophenols with NaBH4. DFT calculations confirmed the contribution of Ag@Pt core-shell structure. s-d Hybridization and charge redistribution existed between Ag cores and Pt shells.
