| 英文摘要 | designing and developing active, cost-effective and stable electrocatalysts for hydrogen evolution reaction (her) are still an ongoing challenge. herein, we report the synthesis of binary transition metal phosphide (coxfe1-xp) nanocubes with different co and fe ratios through a phosphidation process using metal-organic frameworks (mofs) as templates. mof templates contribute well-defined nanocube architectural features after phosphidation, while a suitable phosphidation temperature could allow formation of a crystal structure and maintain the well-defined structure. the incorporation of a binary transition metal results in redistribution of the valence electrons in coxfe1-xp. the changes imply anionic states of the p and fe atoms, which act as active sites and thus have stronger electron-donating ability. when coxfe1-xp nanocubes are employed as electrocatalysts, these characteristic features facilitate the performance of her. remarkably, co0.59fe0.41p nanocubes prepared at 450 degrees c afford a current density of 10 ma cm(-2) at a low overpotential of 72 mv in acidic conditions and 92 mv in alkaline conditions. co0.59fe0.41p nanocubes also exhibit a small tafel slope of 52 mv decade(-1) in acidic conditions and 72 mv decade(-1) in alkaline conditions. moreover, co0.59fe0.41p nanocubes show good stability in both acidic and alkaline conditions. our method produces the highly active her catalyst based on binary transition metal mof templates, providing a new avenue for designing excellent electrocatalysts. |
