Sulfonic acid functionalized mesoporous silicas with various loadings of acid functionality were synthesized, characterized and applied as heterogeneous catalysts for the degradation of metaldehyde, a persistent organic pollutant in water supplies. Nuclear magnetic resonance spectroscopy showed that acetaldehyde was the only by-product of catalytic degradation, and a detailed mechanism is proposed. Kinetic studies revealed that catalyst performance is related to the accessibility of metaldehyde to active sites, such that high sulfonic acid content is undesirable since it reduces pore size, and decreases pore volume and surface area. Acetaldehyde produced via catalytic degradation, was successfully removed via chemisorption on a second mesop...
