Atomically-dispersed Pt supported on WO_x-modified tantalum oxide was developed as a highly active catalyst for selective hydrogenolysis of glycerol, with the productivity of 30.80 g g_Pt⁻¹ h⁻¹ toward 1,3-propanediol. The WO_x species pre-deposited on T-Ta₂O₅ were found to assist the atomic dispersion of platinum. The WO_x-stabilized Pt^δ+ species adsorb hydrogen easily and facilitate the hydrogen heterolytic dissociation, which significantly enhances the capability of in situ generated Brønsted acid sites and the hydrogenation activity. This provides a new strategy for developing bi-functional catalysts for a broad range of hydrogen and acid-involved reaction.

发现带正电荷的铂，以增强甘油氢解为1,3-丙二醇

开发了负载在WO _x改性的氧化钽上的原子分散的Pt，作为用于甘油选择性氢解的高活性催化剂，对1,3-丙二醇的产率为30.80 gg _Pt ^-1 h ^-1。的WO _X物种预先沉积在Ť -Ta ₂ ö ₅被发现协助铂的原子分散体。的WO _X稳定化的铂^{δ +}物种吸附氢容易且便于氢异裂解离，这显著增强的能力原位产生布朗斯台德酸位和氢化活性。这为开发用于广泛的氢和酸反应的双功能催化剂提供了新的策略。
