Phosphate esters and analogs thereof are well known in chemistry and biology by their formidable stability. We used a porous silica material (PSiM) functionalized with amino groups (8.4%) and lanthanum ions (1.5%) to catalyze the cleavage of bis(2,4-dinitrophenyl)phosphate (BDNPP). The functionalized PSiM attracted the substrate from solution and accelerated its hydrolysis by 38-fold in relation to the uncatalyzed reaction at pH 8.14. After an induction period associated to hydration of the catalyst during the first use, the catalytic activity increased in the first reuse to about 600-fold. Supramolecular effects were proposed to drive the catalytic process. Kinetic studies in different pH's showed that the lanthanum ion and amino groups acted mutually in the BDNPP hydrolysis and a reaction mechanism that took this into account was proposed.

磷酸酯及其类似物因其强大的稳定性而在化学和生物学领域广为人知。我们使用经氨基（8.4％）和镧离子（1.5％）官能化的多孔二氧化硅材料（PSiM）催化双酚的裂解（2,4-二硝基苯基）磷酸酯（BDNPP）。相对于pH 8.14的未催化反应，功能化的PSiM从溶液中吸引了底物，并使其水解加速了38倍。在首次使用期间与催化剂水合相关的诱导期后，在第一次重复使用中，催化活性增加到约600倍。提出了超分子效应来驱动催化过程。在不同pH值下的动力学研究表明，镧离子和氨基在BDNPP水解中相互作用，并提出了考虑到这一点的反应机理。
