We report the applicability of a hybrid system comprising a La 3+ -based catalyst and an Au/TiO 2 photocatalyst in the decomposition of chemical weapons. This system is able to perform complete degradation of soman, sarin and VX in less than 1 minute under low basic conditions and visible light irradiation. The combination of methanolysis and photocatalysis can be used for the decomposition of CWA. Herein, we present such a catalytic system, which is able to perform efficient nerve agent decomposition in just 1 minute.
