| 英文摘要: |
| In the past decade, small-pore zeolite SSZ-39 with large pear-shaped cage and 8-ring pore opening has been widely applied in shape selective catalysis of small molecules. In general, zeolite SSZ-39 could give excellent catalytic activity, good resistance to carbon deposition and high thermal stability in several catalytic reactions because of its unique pore architecture and physicochemical properties. In this review, the synthetic developments of zeolite SSZ-39 are comprehensively summarized, including the use of different types of organic structure directing agents (OSDA), the selection of specific silicon and aluminum sources, and the regulation of initial gel compositions; the recent progresses in application of zeolite SSZ-39 such as methanol to olefins, selective catalytic reduction of nitrogen oxides and selective conversion of syngas to propane are briefly introduced; the unsolved challenges related to zeolite SSZ-39 are outlined and the corresponding areas for future exploration in the synthesis and application of zeolite SSZ-39 are discussed. |
