The results showed that hydrogen peroxide, silanols species and TiO〓 didn't have solvolysis activity of propylene oxide. While framework Al, coordinatively unsaturated Ti〓 ions as Lewis acid sites in the framework, Ti-OH and the five member ring active titanium species formed by TS-1, hydrogen peroxide and solvent can catalyze the solvolysis of propylene oxide.

Liquid-phase epoxidation of allyl chloride with hydrogen peroxide was carried out over Ti-MWW, a novel titanosilicate with the MWW structure, to synthesize epichiorohydrin selectively and effectively. Ti-MWW proved to be superior to the conventional TS-1 catalyst in both catalytic activity and product selectivity. Ti-MWW prefers aprotic solvents of acetone and acetonitrile, both of which can restrain the solvolysis of epichiorohydrin, whereas TS-1 favors a protic solvent of methanol.

研究了具有MWW结构的新一代钛硅分子筛Ti-MWW催化剂对烯丙基氯液相环氧化高效合成环氧氯丙烷的催化性能结果表明，Ti-MWW的催化活性以及产物选择性均优于传统的钛硅分子筛TS-1，对于Ti-MWW，合适的溶剂为非质子性溶剂丙酮和乙腈，在该溶剂中环氧化物不易发生溶剂化开环反应；而对于TS-1，合适的溶剂是质子性溶剂甲醇，但甲醇可导致醇醚副产物的生成。

In the second part of the thesis, we developed a very effective assay for the sulfotransferase that catalyzes the sulfation of serine and threonine. It utilized PAPS regenerated from 3-phosphoadenosine 5-phosphate by a recombinant PST using 4-methylumbelliferyl sulfate as the sulfuryl group donor. The change in the fluorescence intensity of 4-methylumbelliferone corresponded directly to the amount of active protein sulfotransferase.

Template-confined growth is a very powerful method for obtaining aligned 1D nanomaterials with adjustable diameter, length and morphology. Porous anodic aluminum oxide templates with different channel structures have been synthesized in our lab, with which the aligned CNT arrays, Y-branching and novel dendriform CNTs have been obtained. Based on the structural characterization of the products, a space-limited and self-catalytic growth mechanism has been proposed accordingly. Roughly speaking, the catalyst particles at the bottom of template channels initiate the nucleation of carbon species, which acts as the seed for subsequent CNT growth.

The reason may be that complex formed by rhodium and halide was difficult to produce the catalytic active species. Therefore halide ion was the poison for the rhodium catalyst in hydroformylation of olefins in ionic liquid. The effect of double long chain cationic surfactant (DCMAB, dicetyl dimethylammonium bromide) on selective hydrogenation of cinnmaldehyde catalyzed with RuCl3·x H2O/TPPTS was studied.
