摘要
利用简单含氧酸盐在水溶液中自组装合成了1个由{Mn-H_2biim}_n链修饰的基于Keggin结构的钼磷酸盐配位聚合物{[Mn_7(H_2biim)_7{PMo_(12)O_(40)}_2Cl]·12H_2O}_n(图1,H_2biim=联咪唑)。大量实验证明,反应中除了反应物的摩尔比外,溶液的pH值是形成目标化合物的关键因素,在不同pH时Strandberg型钼磷酸盐{P_2Mo_5}可转换成Keggin型钼磷酸盐{PMo_(12)}。将该标题化合物作为催化剂应用于电催化还原过氧化氢和合成环己酮乙二醇缩酮的反应,评价了该化合物的电催化和酸催化性能,同时考察了反应时间、起始物比例、带水的用量剂及催化剂用量等参数对反应的影响。初步实验结果表明该化合物是良好的酸催化剂。
A coordination polymer based on Keggin-type molybdophosphate modified by chain-like {Mn/H_2biim/H_2O}_n complex cations,i.e.{[Mn_7(H_2biim)_7{PMo_(12)O_(40)}_2Cl]·12H_2O}_n(Fig.1,H_2biim = 2,2'-biimidazole),was self-assembled by the reaction of simple salts in aqueous solution.A large number of experiments show that the pH value of the mixture is the key factor for the formation of the target compound except the molar ratio of reactants,and {P_2Mo_5} with Strandberg-type can transform into {PMo_(12)} with Keggin-type.The catalytic activity and electrocatalytic activity of this compound were studied and the compound displayed good catalytic perproties.
