Embellished hollow spherical catalyst boosting activity and durability for oxygen reduction reaction
Xu, Pan; Zhang, Jing; Jiang, Gaopeng; Hassan, Fathy Mohamed; Choi, Ja-Yeon; Fu, Xiaogang; Zamani, Pouyan; Yang, Lijun; Banham, Dustin; Ye, Siyu; Chen, Zhongwei (Elsevier, 2018-09)Transition metals hybridized to heteroatom doped carbon material can be regarded as the most promising non-noble candidate for boosting the sluggish kinetics of oxygen reduction reaction (ORR). However, it has always been ... -
Metal-organic frameworks derived platinum-cobalt bimetallic nanoparticles in nitrogen-doped hollow porous carbon capsules as a highly active and durable catalyst for oxygen reduction reaction
Ying, Je; Li, Jing; Jiang, Gaopeng; Cano, Zachary Paul; Ma, Zhong; Zhong, Cheng; Su, Dong; Chen, Zhongwei (Elsevier, 2018-06-05)Pt-based nanomaterials are regarded as the most efficient electrocatalysts for the oxygen reduction reaction (ORR) in proton exchange membrane fuel cells (PEMFCs). However, widespread adoption of PEMFCs requires solutions ... -
Nitrogen-doped hollow porous carbon polyhedrons embedded with highly dispersed Pt nanoparticles as a highly efficient and stable hydrogen evolution electrocatalyst
Ying, Jie; Jiang, Gaopeng; Cano, Zachary Paul; Han, Lei; Yang, Xiao-Yu; Chen, Zhongwei (Elsevier, 2017-10-01)The hydrogen evolution reaction (HER) is a promising alternative method of producing clean and renewable hydrogen resources. Although Pt-based nanomaterials are the most efficient catalysts for HER, their poor stability ... -
Spontaneous weaving: 3D porous PtCu networks with ultrathin jagged nanowires for highly efficient oxygen reduction reaction
Ying, Jie; Jiang, Gaopeng; Cano, Zachary Paul; Ma, Zhong; Chen, Zhongwei (Elsevier, 2018-11-15)We report a simple and efficient surfactant-free method to prepare 3D porous PtCu networks with ultrathin jagged nanowires and controllable composition. The morphological evolution and the influential effects of the important ...
