摘要: Abstract Electrochemical water splitting plays an important role in alternative energy studies, since it is highly efficient and environment-friendly. Accordingly, ideal way of providing to meet the urgent need finding sustainable clean energy. This study presents fabrication CoP attached on multilevel N-doped CNT/graphene (CoP–CNT/NG) hybrids. The carbon structure can enhance electrical conductivity efficiently increase reaction active area immensely. obtained electrocatalyst exhibits great electronic (17.8 s cm−1) HER activity with low overpotential (155 mV at 10 mA cm−2), Tafel slope (69.1 mV dec−1) 0.5 M H2SO4. In addition, CoP–CNT/NG displays prominent electrochemical durability after 18 h.
