The development of highly efficient electrocatalysts for hydrogen evolution reaction is a fundamental undertaking of the hydrogen economy. Herein, we investigated the electrocatalytic performance of conducting polymer (polyaniline, poly (3-aminobenzoic acid)/metal organic framework (HKUST-1) nanocomposites for hydrogen evolution reactions. The results show that the synthesized nanocomposites exhibit the best electrocatalytic efficiency at lower overpotential and the Tafel analysis ( transfer coefficient (α) and Tafel slope (b)) suggests that the rate-determining step is the Volmer (electrochemical discharge) coupled with either Tafel (chemical desorption) or Heyrovsky (electrochemical desorption) reactions.
