We are now facing the emerging problems of how to use the oil,natural gas and coal-based existing energy in a more efficient way and how to develop new energy sources including solar and bio-energy under the resourcediminishing circumstances.In the meantime,environmental protection is a key to the sustainable development of the world.Currently,zeolites with stable,uniform and intricate micropores as well as good shape selectivity are regarded as one of the most important heterogeneous catalysts for solving problems of the energy and the environment.In this field, Chinese scientists have made considerable contributions such as synthesis of extra-large microporous JDF-20,industrial application of SAPO-34 catalysts in methanol-to-olefin (MTO),organotemplate-free synthesis of ZSM-5 and Beta,industrial application of titanosilicate zeolite catalysts in hydrocarbon oxidations,creation of a series of ordered mesoporous materials,and preparation of hierarchically mesoporous zeolites.It is really cheerful to have witnessed the exciting and rapid growth in this field made by the Chinese scientists.Therefore,we are pleased to invite a number of them to present their excellent work and to share their viewpoints on the development of zeolite research in this special issue of Chinese Journal of Catalysis.We are also very glad to have a number of well-known scientists from both academic and industrial institutions outside of China to showcase their leading work in this special issue.
