A outperform and active non-noble electrocatalyst for hydrogen evolution reaction is hotspot in the current research activities for the hydrogen production with zero carbon dioxide emission. The requirement for stable and durable electrocatalysts for active HER is of exhibit high challenges for the present and future generations. Considering the role of single-component systems of Sn, Co, and Cu, for energy applications, here we present the ternary oxide system of these three elements with a ratio of copper nanoparticles. In a basic medium, the best 46% Cu-doped structure exhibited the highest response for hydrogen production by giving 10 mA/cm² at 0.31 V. The Tafel slope of this composition (46% Cu) of material is the lowest ever reported for hydrogen production for Cu-doped electrocatalysts. The electrocatalysts exhibit excellent stability and high durability. Chronopotentiometry test was performed at 10 mA/cm² & current density suffers no significant loss in the potential for 10 hours in basic media, respectively. The Cu–SnCo system is directly used nano electrocatalyst for efficient HER. The key element in the success of newly developed electrocatalyst is the greater amount of copper nanoparticles which has played dominant role in hydrogen gas production. To understand new fundamental questions related to electrocatalyst design to achieve very effective and for the stable nonprecious electrocatalysts for overall water splitting and to strengthen renewable energy reservoirs and to minimize the global warming effects. This nanocomposite catalyst is an alternative and promising material for other co-existing applications such as energy storage devices. The developed material can be applied in the other competing fields such as lithium ion batteries, solar cells, energy storage devices, and photochemical water splitting.
