Реферат: Photocatalytic materials able to generate hydrogen from water upon sunlight are being actively researched. Still, in many cases the detailed mechanisms of photophysical and photochemical processes behind hydrogen evolution remain unexplored. In this work we design and study new heterojunction photocatalysts based on tungsten oxides and ZnTCPP (meso-tetra(4-carboxyphenyl)porphyrin) chromophore. It is shown that the hydrogen production in ZnTCPP/WO3 composites is higher than the sum of individual productions, indicating a successful synergy in heterojunction. Furthermore, we apply a combination of continuous wave (CW) and time-resolved (TR) electron paramagnetic resonance (EPR) spectroscopies to reveal intermediate excited states, examine electron transfer and side reactions in a series of ZnTCPP/WO3 photocatalysts. Data obtained by EPR are analyzed together with hydrogen evolution efficiencies, indicating further routes to improve photocatalytic performance of these materials.
