Abstract Noble metal‐based electrocatalysts are impractical for large‐scale manufacture due to their high cost, limited availability, and poor long‐term stability in performing several functions. Hence, an alternative is the need of hour that emphasizes blending metals ceramic property materials with compelling electroconductivity. In this research, we synthesized two bare materials, Nb 2 AlC MAX (Nb‐MX) phase graphitic carbon‐nitride (GCN) sheets using calcination method which then converted into a composite (Nb‐MX/GCN) material through wet impregnation technique. The electrochemical investigations were conducted assess catalytic efficacy material. Nb‐MX/GCN electrocatalyst exhibited outstanding electrocatalytic efficiency hydrogen evolution reaction (HER) oxygen (OER) alkaline environment. catalyst exhibits significantly low overpotential just 66 mV 450 HER OER performance, respectively, at current density 10 mA cm −2 1.0 M KOH solution. addition, activity no change over 24 h indicated excellent This performance surpassed previously reported electrocatalysts.

Water can be sustainably and ecologically converted by electrocatalysts into hydrogen oxygen, which, in turn, energy. However, the advancement of using water as green energy is hampered limitations study high-performance catalysts. The purpose this was to construct an electrocatalyst anchoring well-dispersed multiwalled carbon nanotubes (MWCNTs) on nickel–copper (NiCu-MOF) nanoblocks through a simple solvothermal method. synthesis NiCu-MOF@MWCNTs demonstrated exceptional electrocatalytic performance for evolution reaction (HER) oxygen (OER) alkaline medium. At 10 mA cm–2 1.0 M KOH, OER HER catalyst displays relatively low overpotential, with only 220 78 mV, respectively. Furthermore, catalytic activity remained unchanged 24 h KOH. This superior majority that have been reported. achieved utilizing strong synergy exists between MWCNTs bimetallic (Ni–Cu) nano blocks present metal–organic framework. enhanced nanocomposite attributed synergistic impact caused its various components.
