In situ formation of molecular Ni-Fe active sites on heteroatom-doped graphene as a heterogeneous electrocatalyst toward oxygen evolution
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 ...
Fe-based metallopolymer nanowall-based composites for Li-O2 battery cathode
Metallopolymer nanowalls were prepared through a simple wet-chemical process using reduced graphene oxides as heterogeneous nucleation aids, which also help to form conductive electron paths. The nanowalls grow vertically ...
Compressed hydrogen gas-induced synthesis of Au–Pt core–shell nanoparticle chains towards high-performance catalysts for Li–O 2 batteries
Herein we reported a green synthetic route for the preparation of Au–Pt core–shell nanoparticle chains in a two-step route without the use of any surfactants. In the synthesis, compressed hydrogen was used as a reducing ...
