Neonicotinoid compounds are an important family of insecticides which have attracted recent global attention in terms of environmental concerns due to their large-scale applications. Photodegradation is a relevant approach in pesticide degradation in the environment, also related to one of the most important aspects of pesticides persistence in the environment. In this work, studies on neonicotinoids photodegradation/photostability modulation by the addition of metal-containing mesoporous materials have been attempted.  The aqueous photodegradation dynamics of acetamiprid, investigated under ultraviolet light irradiation using Cu and Ag-SBA-15 materials, can be described with first order kinetics equation. The addition of the metal-containing mesoporous materials was found to extend the half-life of acetamiprid photodegradation in aqueous solutions.
