Porous nickel cobalt sulfide shells decorated on a CuO nanowire core supported on a CuO/CF hybrid foam form the unique 3D self-standing core–shell dendritic electrocatalyst of Ni–Co–S@CuO/CF for OERs, with high activity and long-term cycling cyclic stability.
TiNb2O7 anode constructed with carbon-coated nanosheet arrays on carbon cloth is prepared by a facile solvothermal process and post carbon-coating for the first time. With nanosized diffusion-length and reduced polarization...
