been found to be strongly related with the properties and structure of each catalyst.Graphical AbstractThe selectivity of zirconium phosphate amorphous [Zr(HPO4)2·H2O; ZrPA], sodium exchanged zirconium phosphate amorphous [Zr(NaPO4)2; NaZrPA], potassium exchanged zirconium phosphate amorphous [Zr(KPO4)2; KZrPA], zirconium phenylphosphonate amorphous [Zr(O3PC6H5)2; ZrPPA], zirconium carboxyethylphosphonate
包括金属磷酸盐和膦酸盐在内的层状材料已在多个领域得到广泛研究,它们在大量氧化反应中充当良好的选择性催化剂。磷酸锆无定形 [Zr(HPO4)2·H2O; ZrPA],钠交换磷酸锆无定形[Zr(NaPO4)2; NaZrPA],钾交换磷酸锆无定形[Zr(KPO4)2; KZrPA],苯基膦酸锆无定形[Zr(O3PC6H5)2;ZrPPA],羧乙基膦酸锆[Zr(O3PCH2CH2COOH)2;ZrCEP]和羧乙基膦酸铝[Al3(OH)3(O3PCH2CH2CO2)2·3H2O;AlCEP] 在乙酸中通过过氧化氢对环戊酮、对甲氧基苯甲醛和 2,4,6-三甲基苯甲醛进行 Baeyer-Villiger 氧化反应中作为选择性催化剂制备、表征和评估。δ-戊内酯、对甲氧基苯酚和2,4的选择性,已发现6-三甲基苯酚与每种催化剂的性质和结构密切相关。图文摘要磷酸锆无定形[Zr(HPO4)2·H2O; ZrPA
