This paper presents a pyroelectric approach for the synthesis of metal–BaTiO3 hybrid nanoparticles (NPs) and demonstrates enhanced performance on degradation dye solution using such NPs. During process, rapid temperature oscillation accelerated electron generation at surface barium titanate (BTO) NPs that were dispersed in either aqueous or nonaqueous solutions. These generated electrons used to reduce metal salts BTO without need reducing reagent. The Au–BTO synthesized by showed higher pyrocatalytic efficiency than physically mixed solutions Au Compared conventional processes, this additional reagents not only offers an alternative strategy metal–pyroelectric materials but also opens new way harvest thermal energy efficient pyrocatalysis process.
