摘      要：Here,N-and P-doped carbon-carbon nanotube CoP(NPC-CNTs-CoP)nanoparticles dodecahedra are achieved by multistep calcination of the Zn-doped zeolitic imidazolate framework ZIF-67 precursor(ZnCo-ZIF).In the structures,the presence of N and P atoms,abundant CNTs and the CoP nanoparticles can enhance electrochemical activity and promote the structural stability of *** the temperature increases,the Zn contents gradually reduce to zero,which provides more active sites for electrochemical ***,the high specific surface area and microporous behavior of NPC-CNTsCoP-9 make it excellent in electrocatalytic ***-CoP-9 shows a low overpotential of 224 mV at10 mA·cm^-2 in 1.0 mol·L^-1 KOH *** strategy of zeolitic imidazole framework-derived transition metal phosphides will provide a new sight for developing energy conversion materials.
