heat-treatment process can act both as mesoporous templates and base-resistant reinforcement for zirconia. The resultant mesoporous K-ZrO2 catalysts with high surface area show excellent catalytic performance in Knoevenagel condensations, especially for substrates with large molecular size. The mesoporous KZ also show enhanced activity when compared to KZ synthesized from traditional zirconium hydroxides. To the
通过负载KNO 3的UiO-66
金属有机骨架的直接热处理工艺设计和合成了介孔K-ZrO 2。非常有趣的是,在热处理过程中形成的碳中间体既可以充当介孔模板,又可以充当
氧化锆的耐碱增强材料。所得的具有高表面积的中孔K-ZrO 2催化剂在Knoevenagel缩合反应中表现出出色的催化性能,特别是对于大分子底物。与由传统的
氢氧化锆合成的KZ相比,中孔KZ还显示出增强的活性。据我们所知,这是首次使用MOF前体合成金属氧化物型固体碱。
