description |
Design and fabrication of three dimensional Ti3AlC2 MAX/TiO2 composite immobilized over monolithic support was obtained through sol-gel approach. With partial oxidation and incorporation of Ti3AlC2 essentially promotes light absorption, charge transfer and extends photo-induced charge carrier lifetime. The highest CO yield of 1566 »μmol »g-cat-1 was obtained over Ti3AlC2 MAX/TiO2, being 6.8 folds higher than pure TiO2 NPs. Performance of structured composite tested in methane steam reforming (MSR), methane dry reforming (MDR) and methane bi-reforming (MBR) reveals 1.2 and 1.6 folds higher activity in MBR than using MDR and MSR, respectively. Similarly, quantum yield in a monolith photoreactor was 3.5 folds higher than using a fixed-bed system. This divulges that MBR gave proficient oxidation and reduction reactions in electron-rich 3D MAX structure, whereas, monolith photoreactor provides larger photon-energy consumption with improved sorption process to boost production of CO and H2 with enhanced stability. Thus, this work demonstrated 3D Ti3AlC2 MAX/TiO2 a promising catalyst and monolith photoreactor an efficient photon flux harvesting system for boosting hydrogen rich syngas production. |
