Influence of La-doping on the CuO/ZrO2 catalysts with different Cu contents for hydrogenation of dimethyl oxalate to ethylene glycol
Autor: Xiaohui Guo, Huimin Liu, Zhenfeng Wang, Meihui Wang, Yaxiong Wang, Gewen Yu, Jian Ding
Publikováno v: New Journal of Chemistry. 45:18102-18113
Herein, Cu/ZrO2 catalysts containing different Cu contents with or without La-doping were used for the selective hydrogenation of dimethyl oxalate (DMO) to ethylene glycol (EG). Effects of La addition and the optimal Cu content were thoroughly invest

ACS Omega, Vol 5, Iss 43, Pp 28212-28223 (2020)
The CuO–La2O3/ZrO2 catalysts calcined at different temperatures from 500 to 800 °C were studied for the hydrogenation of oxalates to ethylene glycol (EG). Along with the increase of calcination temperatures, the BET surface area, pore volume, and

Effective 'exfoliation' of Cu/ZrO2 by varying Cu content as high performance catalysts for dimethyl oxalate hydrogenation to ethylene glycol
Autor: Gewen Yu, Litong Ma, Shengyun Chen, Fan Hongyan, Wenxiu He, Yaxiong Wang, Jiangang Chen, Jian Ding, Huimin Liu
Publikováno v: Catalysis Communications. 121:62-67
Here, an interesting strategy for “exfoliating” Cu/ZrO2 catalyst into nano-layers by varying Cu content is reported. The unique layered structures with enhanced surface properties endow Cu/ZrO2 catalyst with more active sites interacting with the

Oxadiazole derivatives as bipolar host materials for high-performance blue and green phosphorescent organic light-emitting diodes
Autor: Guoxiang Li, Wang Yanming, Gewen Yu, Duan Keke
Publikováno v: RSC Advances. 9:32010-32016
By combining two n-type groups, pyridine and oxadiazole, with one p-type carbazole group, two novel bipolar hosts, namely 2-(3-(9H-carbazol-9-yl)-[1,1′-biphenyl]-3-yl)-5-(pyridin-2-yl)-1,3,4-oxadiazole (PyOxd-mCz) and 2-(4′-(9H-carbazol-9-yl)-[1,

ZnO-Al2O3-promoted CuO/ZrO2 catalyst prepared by oxalate gel-coprecipitation for the conversion of water-bearing materials
Autor: Gewen Yu, Jian Ding, Wenxiu He, Lan Dawei, Jiangang Chen, Yaxiong Wang, Juan Zhang, Zhou Chenliang
Publikováno v: Journal of Sol-Gel Science and Technology. 85:382-393
Generally, ZrO2 facilitates the reactions of O-containing species, which result in the loss of activity or the sintering of Cu species via intimate interaction between water and CuO/ZrO2 catalysts. Indeed, the CuO/ZrO2 catalysts (CZo) prepared by oxa
