摘要 研究了各种条件下[Ir(NO)Cl~5]^-的电子光谱和红外光谱的变化,讨论了[Ir(NO)Cl~5]^-与[Ir(NO)~2Cl~5]^3^-之间的转化与平衡及[Ir(NO~2)Cl~5]^3^-的配位体交换反应.在稀盐酸溶液中[Ir(NO~2)Cl~5]^3^-有水合作用,由[Ir(NO~2)Cl~5]^3^-转变成[Ir(NO~2)(H~2O)Cl~4]^2^-的表观活化能E~a的平均...
高分散度Pt-Ir疏水催化剂制备及氢-水液相交换催化性能研究(Highly Dispersed Pt-Ir Hydrophobic Catalysts: Preparation and Catalytic Activity for Hydrogen-water Liquid Exchange Reaction)
