The insertion of multicomponent photoactive guests into zeolite channels improves photoredox and photocatalytic efficiency. In this report, we present the synthesis of a variety of composites comprising Pd-doped TiO2 and zeolite NaY (ZeoNa-Y@TiO2/Pd) and investigate their photocatalytic efficacy. The zeolite NaY serves as a host for the active titanium dioxide phase, while the palladium nanoparticle acts as a co-catalyst. The zeolite NaY in the catalyst composition enhances the efficiency by hindering the electron-hole recombination. The most efficacious catalyst shows a hydrogen production rate of 3.5 mmol.g−1.h−1. The degradation of the methylene blue dye reaches discoloration and mineralization above 98%.
