文摘

Ti1.4V0.6Ni@Mo2C and Ti1.4V0.6Ni@WC composites are prepared by ball-milling. The structure of composites contains icosahedral quasicrystalline phase. Ti1.4V0.6Ni@WC composites show superior capacity conservation rate increased by 29.5% compared with Ti1.4V0.6Ni alone. Copacetic electrocatalytic activity and anti-pulverization ability are improved by coating with Mo2C or WC.
