Abstract

Abstract: In this communication, we report on the solvothermal preparation of spinel ZnCo2O4/N-doped carbon nanotube (ZnCo2O4/NCNT) composite. As a novel oxygen reduction reaction (ORR) electrocatalyst, the ZnCo2O4/NCNT composite shows high activity via a four-electron pathway in alkaline solution. Such catalyst also exhibits superior methanol tolerance ability and durability over commercial Pt/C catalyst. [Copyright &y& Elsevier]

Abstract

Abstract: In this communication, for the first time, we demonstrate the electrodeposition of Ni3S2 on ZnO (ZnO@Ni3S2) array supported on nickel foam. We further demonstrate the direct use of ZnO@Ni3S2 array as a binder-free electrode material for supercapacitors and this electrode exhibits a very high specific capacitance of 1529 F g−1 at a current density of 2 A g−1, good rate capability and cycling stability.

Abstract

Abstract: In this communication, for the first time, we demonstrate the fast and facile preparation of porous FeF3 nanospheres using solvent exchange from FeF3 aqueous solution to ethanol. We further demonstrate the use of such FeF3 nanospheres as cathode materials for rechargeable lithium-ion batteries with good rate capability and cycling performance. [Copyright &y& Elsevier]
