Novel heterogeneous catalysts were prepared by impregnation of titania with a solution of cobalt acetate/melamine and subsequent pyrolysis. The resulting materials show an unusual nitrogen‐modified titanium structure through partial implementation of nitrogen into the support. The optimal catalyst displayed good activity and selectivity for challenging pyridine hydrogenation under acid free conditions
通过用乙酸钴/三聚氰胺溶液浸渍二氧化钛并随后进行热解来制备新型的非均相催化剂。所得材料通过将氮部分引入载体中而显示出不同寻常的氮改性钛结构。最佳的催化剂显示出良好的活性和选择性,可以在无酸条件下以水为溶剂,挑战吡啶的氢化反应。
