A stepwise fabrication of MFI nanosheets in accelerated mode
A series of micro-mesoporous materials with nanosponge structure were synthesized in accelerated mode. The influence of the perchlorate oxyanion promoter on the materials characteristics was thoroughly investigated. It was shown that the formation of nanosponge structure with high amount of promoter occurs through the consecutive steps that can be easily detected. The effect of promoter concentration on the crystalline structure was demonstrated under simple hydrothermal conditions. A novel hydrothermal method was developed to synthesize the micro-mesoporous materials with nanosponge structure in 18 h.
