Mesoporous Silica for Triphase Nucleophilic Substitution Reactions
Autor: Shouai Feng, Yixin Li, Hong Liu, Jiangfeng Huang, Chang Ji, Liang Qiao, Baohong Liu, Ji Ji
Publikováno v: CHIMIA, Vol 72, Iss 7-8 (2018)
Mesoporous silica SBA-15 is shown to be a very efficient alternative to phase transfer catalyst salts for two-phase nucleophilic substitutions. The two-phase reaction can efficiently take place in the absence of PTCs. The high catalytic activity and

Activated carbon catalyzing the formation of carbon nanotubes
Autor: Jianfeng Zheng, Jianghong Zhao, Zhenping Zhu, Shouai Feng, Jinling Song
Publikováno v: Materials Research Bulletin. 45:1234-1239
Activated carbon (AC), a common carbon material, is employed as catalyst to synthesize carbon nanotubes (CNTs) through chemical vapor deposition (CVD) and detonation-assisted CVD methods. The results show AC can effectively catalyze CNT formation. Fr
