title: Preparation of in-situ Pt nanoparticles into frameworks of mesoporous silica for improving thermal stability.
abstract: The Pt/sulfur-containing mesoporous silica (SMS) was obtained through in-situ co-condensation of TESPTS and TEOS in the presence of a triblock copolymer template. Strong interaction between the Pt NPs and S moieties of TESPTS in the SMS frameworks played an important role in the stabilization of Pt NPs against the sintering or coalescence problems. The Pt/SMS significantly improved the thermal stability at high temperature.
