This article mainly covers the recent development of synthesis, characterization and catalytic applications of hierarchical pore zeolite materials. Based on mechanisms of hierarchical pore formation, synthetic approaches of hierarchical pore zeolite materials including hydrothermal and chemical treatments, acid leaching, base leaching, and templating are systematically reviewed, especially, categorizing the synthetic method of templating. The relevance of characterization techniques for analysis of hierarchical pore zeolite materials, i.e., their structure, texture, hydrothermal stability, and acid properties are subsequently described. Finally, the applications of hierarchical pore zeolite materials as catalysts to acid-catalyzed reactions, environmental catalysis, oxidation reactions and synthesis of fine chemicals are focused, providing guide for the potential of hierarchical pore zeolite materials in catalytic applications.
