In situ formation of molecular Ni-Fe active sites on heteroatom-doped graphene as a heterogeneous electrocatalyst toward oxygen evolution

Wang, Jiong; Gan, Liyong; Zhang, Wenyu; Peng, Yuecheng; Yu, Hong; Yan, Qingyu; Xia, Xinghua; Wang, Xin (2018)

Molecularly well-defined Ni sites at heterogeneous interfaces were derived from the incorporation of Ni2+ ions into heteroatom-doped graphene. The molecular Ni sites on graphene were redox-active. However, they showed poor ...
