UV resonance Raman spectroscopic insight into titanium species and structure-performance relationship in boron-free Ti-MWW zeolite

Autor: Zhendong Wang, Fu Wenhua, Shilin Zhang, Wei Liu, Sun Hongmin, Yangdong Wang, Guiju Tao, Weimin Yang, Zhang Bin, Shaoqing Jin

Publikováno v: Journal of Catalysis. 353:305-314

The titanium species and structure-performance relationship in boron-free Ti-MWW zeolite have been thoroughly studied by 244 nm excited UV resonance Raman spectroscopy for the first time. It was surprisingly found out that acid treatment not only rem

Generic synthesis and versatile applications of molecularly organic–inorganic hybrid mesoporous organosilica nanoparticles with asymmetric Janus topologies and structures

Autor: Luodan Yu, Yu Chen, Heliang Yao, Ping Huang, Guiju Tao, Jiamin Zhang, Meiying Wu, Long Zhang, Zhengyuan Bai, Chen Dai

Publikováno v: Nano Research. 10:3790-3810

Precise control over the morphology, nanostructure, composition, and particle size of molecularly organic–inorganic hybrid mesoporous organosilica nanoparticles (MONs) still remains a major challenge, which severely restricts their broad applicatio

Insight into the formation of framework titanium species during acid treatment of MWW-type titanosilicate and the effect of framework titanium state on olefin epoxidation

Autor: Qiangqiang Luo, Sun Hongmin, Jie Zhang, Wei Liu, Shaoqing Jin, Guiju Tao, Donghao Deng, Weimin Yang

Publikováno v: Microporous and Mesoporous Materials. 314:110862

Acid treatment before calcination is indispensable for MWW-type titanosilicate to achieve excellent catalytic performance. Our previous study indicated that not only about half of the absolutely dominant low active non-framework TiO6 species in as-sy
