@article { , title = {Co2N nanoparticles embedded N-doped mesoporous carbon as efficient electrocatalysts for oxygen reduction reaction}, abstract = {Co-N-C electrocatalysts have attracted great attention in electrocatalytic ORR (oxygen reduction reaction) field. In this work, we propose to prepare Co 2 N nanoparticles embedded N-doped mesoporous carbon by a facile method including in situ copolymerization and pyrolysis under NH 3 atmosphere. The results show that more N atoms can be doped in carbon framework by NH 3 pyrolysis, it is also found that pyrolysis temperature and Co content can influence the ORR performance of samples. The sample prepared by adding Co precursor and pyrolysis at 700 °C has high N content (11.86 at.\%) and relative large specific surface area (362 m 2 g −1 ), and it also exhibited superior electrocatalytic ORR performance in terms of E onset (−0.038 V vs. SCE), E 1/2 (−0.126 V vs. SCE) and large current density (5.22 mA cm −2 ). Additionally, the sample also shows better stability and resistance to methanol poisoning than Pt/C catalyst. The synergistic effect of Co-N active centers and hierarchical porous structures contribute the excellent electrocatalytic activity, which are considering as alternative catalysts for ORR in full cells.}, doi = {10.1016/j.apsusc.2018.12.204}, issn = {0169-4332}, journal = {Applied Surface Science}, pages = {555-563}, publicationstatus = {Published}, publisher = {Elsevier}, url = {https://hull-repository.worktribe.com/output/1198557}, volume = {473}, keyword = {Specialist Research - Other, Surfaces, Coatings and Films}, year = {2019}, author = {Guo, Dakai and Tian, Zhengfang and Wang, Jiacheng and Ke, Xuebin and Zhu, Yufang} }
