Hybrid mesoporous molecular sieve materials with hexagonal mesoporous structure and covalent bonded polyoxometalates were synthesized based on tetraethoxysilane anti lacunary polyoxometalate, SiW11, via sol-gel method in the presence of triblock copolymers P123 as the structure-directing agent. The influences of molar ratio of inorganic precursors and aging temperature on the structure and the loadings of SiW11 in the hybrid materials were investigated. Some reaction details in the synthesis were revealed.

Hechi-Yishan fault zone is located in the north of Guizhong depression, which general strike is NW-EW and consists of a series of obduction fault. Generally, there are two main faults, the fault-fold belt about 5-20km is made of main faults, subsidiary faults and concomitant folds; The dip of main faults is N or S; It can be divided into four different structural sections along its strike (Hechi section, Yishan section, Liucheng section and Yingshan section). There are some differences among these sections in structure characteristic, such as fault structure, associated structure, fold association style, deformation of rock, and so on.
