Effect of oxide additives on the hydrotalcite derived Ni catalysts for CO2 reforming of methane
Niu, Juntian; Liland, Shirley Elisabeth; Yang, Jia; Rout, Kumar Ranjan; Ran, Jingyu; Chen, De (Journal article; Peer reviewed, 2018)Here we provide new mechanistic and kinetic insights into the functions of oxides on Ni catalysts in methane dry reforming combining kinetic studies with density functional theory (DFT) calculations. Hydrotalcite derived ... -
New mechanism insights into methane steam reforming on Pt/Ni from DFT and experimental kinetic study
Niu, Juntian; Wang, Yalan; Qi, Yanying; Dam, Anh Hoang; Wang, Hongmin; Zhu, Yi-An; Holmen, Anders; Ran, Jingyu; Chen, De (Peer reviewed; Journal article, 2020)In this contribution, we combine density functional theory (DFT) calculations, experimental kinetic study and DFT-assisted analysis to elucidate the impact of the interface of monolayer Pt on the Ni surface on catalytic ... -
Understanding the mechanism of CO2 reforming of methane to syngas on Ni@Pt surface compared with Ni(1 1 1) and Pt(1 1 1)
Niu, Juntian; Ran, Jingyu; Chen, De (Peer reviewed; Journal article, 2020)CO2 reforming of methane (DRM) is a promising reaction for the carbon cycle in nature. Ni was found to be active in this process. However, single component Ni catalysts cannot meet the stability, activity and selectivity ... -
Unraveling Enhanced Activity, Selectivity, and Coke Resistance of Pt–Ni Bimetallic Clusters in Dry Reforming
Niu, Juntian; Wang, Yalan; Liland, Shirley Elisabeth Sjø; Regli, Samuel K.; Yang, Jia; Rout, Kumar Ranjan; Luo, Jun; Rønning, Magnus; Ran, Jingyu; Chen, De (Journal article; Peer reviewed, 2021)By introducing Pt atoms into the surface of reduced hydrotalcite (HT)-derived nickel (Ni/HT) catalysts by redox reaction, we synthesized an enhanced active and stable Ni-based catalyst for methane dry reforming reaction. ...
