Atomic Cu-N-P-C Active Complex with Integrated Oxidation and Chlorination for Improved Ethylene Oxychlorination
Ma, Hongfei; Zheng, Xiuhui; Zhang, Hao; Ma, Guoyan; Zhang, Wei; Jiang, Zheng; Chen, de (Journal article; Peer reviewed, 2023)Fine constructing the chemical environment of the central metal is vital in developing efficient single-atom catalysts (SACs). Herein, the atomically dispersed Cu on the N-doped carbon is modulated by introducing CuP ... -
CO Oxidation over Alumina-Supported Copper Catalysts
Ma, Guoyan; Wang, Le; Wang, Xiaorong; Li, Lu; Ma, Hongfei (Peer reviewed; Journal article, 2022)CO oxidation, one of the most important chemical reactions, has been commonly studied in both academia and the industry. It is one good probe reaction in the fields of surface science and heterogeneous catalysis, by which ... -
Nitrogen‐Doped Carbon-Assisted One‐pot Tandem Reaction for Vinyl Chloride Production via Ethylene Oxychlorination
Ma, Hongfei; Ma, Guoyan; Qi, Yanying; Wang, Yalan; Chen, Qingjun; Rout, Kumar Ranjan; Fuglerud, Terje; Chen, De (Peer reviewed; Journal article, 2020)A bifunctional catalyst comprising CuCl2/Al2O3 and nitrogen‐doped carbon was developed for an efficient one‐pot ethylene oxychlorination process to produce vinyl chloride monomer (VCM) up to 76 % yield at 250 °C and under ... -
Thermal and Rheological Performances Evaluation of a Modified Biopolymer for Fracturing Fluid System
Ma, Guoyan; Wang, Le; Hao, Chao; Du, Chunbao; Ma, Hongfei (Journal article; Peer reviewed, 2022)Developing an efficient fracturing fluid system is an enduring hot topic in the petrochemical industries, especially regarding the exploitation of limited oil. Biopolymers, especially polysaccharides (e.g., konjac gum, ...
