英文摘要 | a low-temperature strategy to fabricate hierarchical aluminophosphate-based molecular sieves has been developed without the assistance of surfactants. the facile synthesis results in cylinder-like sapo-5 (afi) composed of oriented attached nanosheets with a thickness of 40-100 nm. the main exposed surface of the nanosheets is revealed by the saed pattern to be the {001} plane, implying a short path for molecular diffusion in the one-dimensional 12-membered ring channel. investigation on the crystallization process demonstrates that low temperature retards the crystal growth along the c-direction in sapo-5 and the ordered architecture forms via a nanosheet formation and oriented attachment process. the aggregated morphology of sapo-5 is template-dependent, which may be modified/changed by varying the template in the system. the low-temperature strategy is also successfully extended to the preparation of metal-containing aluminophosphate molecular sieves. the obtained meapo-5 (me = co, mn, and cr) and a novel cha/aei intergrowth coapo molecular sieve also possess hierarchical structures with nanosheet-assembled morphology. remarkably, the present self-assembled afi crystals exhibit an obvious improvement in catalytic reactions. this facile method provides a new way for the long-range organization of nanosized building blocks to fabricate hierarchical nanostructures. |
