Research and Application Development of Catalytic Redox Technology for Zeolite-Based Catalysts

Abstract

Zeolites are porous materials with plentiful and adjustable pore structures, which are widely applied in various fields such as fossil fuel energy conversion, preparation of clean energy, chemical product conversion, CO2 capture, VOC treatment, and so on. Zeolites exhibited advantageous adsorption compared with traditional adsorbents such as activated carbon; in addition, they can also provide abundant reaction sites for various molecules. The chemical composition, structural acidity, and distribution of pore size can distinctly affect the efficiency of the reaction. The modification of zeolite structure, the development of novel and efficient preparation methods, as well as the improvement of reaction efficiency, have always been the focus of research for zeolites.

Challenges and opportunities for zeolite-based catalysts in catalytic oxidation of volatile organic compounds

“…12–14 On the other hand, zeolite-supported noble metals or transition metal oxides have been reported as catalysts for catalytic oxidation of VOCs since the end of the last century and boosted in the past decade, 6,15 but the commercialized applications of zeolite-based catalysts in the oxidation of VOCs were seldom reported, suggesting the challenges for zeolite-based catalysts in these oxidation processes. Although review articles have summarized the development process of zeolite-based catalysts in the oxidation of VOCs as well as the relationship between the structure of zeolite and catalytic oxidation performances toward different types of target VOCs, 15–18 the challenges for the design and optimization of zeolites were rarely discussed. In this perspective, we aim to give a concise overview of the challenges as well as the corresponding opportunities for zeolite-based catalysts in the oxidation of VOCs, proposing strategies for preparation of highly efficient zeolite-based catalysts in the future.…”
