摘要
应可持续发展与绿色化学的需要,非均相催化剂替代传统的均相催化剂引起研究者的广泛重视。其中,金属基介孔固体碱具有比表面积大、腐蚀性小、传质速率快、易分离等优点,是一种理想的绿色催化剂。本文综述了近年来制备不同的金属基介孔固体碱(包括MgO、类水滑石(HTs)及改性的Al2O3、ZrO2、CeO2)的研究进展,重点讨论了软模板法、硬模板法、溶剂挥发自组装法、无模板剂法等制备各种金属基介孔固体碱的方法和机理。此外,还介绍了金属基介孔氧化物在催化、储能与环境领域中的实际应用。最后,简要分析了金属基介孔固体碱制备过程中存在的问题,并展望其在未来的发展趋势,为新型金属基介孔固体碱的构筑提供了新的思路。
For the demands of sustainable development and green chemistry, the use of heterogeneous catalysts instead of conventional homogeneous ones has received increasing attention. Among various heterogeneous catalysts, mesoporous solid bases are extremely desirable in green catalytic processes, due to their advantages of high specific surface, negligible corrosion, accelerated mass transport and easy separation. Great progress has been made in mesoporous solid bases in the last decade. In addition to their wide applications in the catalytic synthesis of organics and fine chemicals, mesoporous solid bases have also been used in the field of energy and environmental catalysis. In this review, we provide an overview of recent research progress in the preparation and application of metal-based mesoporous solid bases(including MgO,hydrotalcite-like compounds, modified-Al2O3,modified-ZrO2, and modified-CeO2), which is basically grouped by the metal type and illustrated with typical examples. The advantage, disadvantages and mechanisms for four main synthesis methods, including soft-template method, hard-template method, solvent evaporation-induced self-assembly(EISA) synthesis and solvent-free synthesis are discussed and compared in detail. Moreover, their applications in the fields of catalysis, energy storage and environment are briefly introduced as well. Finally, the existing problems of the preparing metal-based mesoporous oxides are briefly discussed, and the strategies are provided for the construction of novel metal-based mesoporous solid bases.
