摘要:Solar-induced photothermal catalysis attracts substantial attention because of the significant energy savings and environmental friendliness. Herein, a simple hydrothermal technique is developed to construct W18O49/SAPO-34 composite with hierarchical pore networks as a low-cost and efficient photothermal catalyst for methanol-to-olefins (MTO). It was demonstrated that W18O49 nanorods were fully decorated over SAPO-34 micro-cubes, leading to a strong photo-to-thermal effect. The composite catalysts showed a methanol conversion of ~ 90% and ethylene selectivity of ~ 60%, much higher than bare W18O49 semiconductors and pure SAPO-34 zeolite. The excellent methanol dehydration performance is benefited from the strong plasmon absorption in the visible and NIR region, the intense photothermal conversion effect by localized plasmon heating on the W18O49 nanorods, and synergistic catalysis of W18O49 and SAPO-34 zeolite. This work demonstrates that the combination of defected semiconductor and zeolite is an effective strategy to construct photothermal catalysts for energy and environmental applications. ? 2022, The Authors.
