Development of Polyethylenimine (PEI)-impregnated mesoporous carbon spheres for low-concentration CO2 capture
Chen, Qingjun; Wang, Siyu; Rout, Kumar Ranjan; Chen, De (Peer reviewed; Journal article, 2020)A novel low-concentration CO2 capture material (PEI/MCS) was developed by loading polyethylenimine (PEI) over mesoporous carbon spheres (MCS) with high porosity. The effects of pore structure, PEI loading, capture temperature, ... -
Effect of trace potassium on hydrogen adsorption and dissociation on hcp cobalt: A density functional theory study
Chen, Qingjun; Svenum, Ingeborg-Helene; Gavrilovic, Ljubisa; Chen, De; Blekkan, Edd Anders (Journal article; Peer reviewed, 2018)Trace amounts of potassium (K) have a significant influence on the activity and selectivity of cobalt-based catalysts in Fischer–Tropsch synthesis (FTS), in which hydrogen adsorption and dissociation is one of the initial ...
