Hydrogen is zero-emission fuel production for a clean environment as alternative effective the energy source is still moreover, an effective challenge in near future due to the lack of efficient and inexpensive catalysts. An efficient electrocatalysts structure having logical design which holds a paramount significance for the hydrogen evolution reaction (HER) but rarely noble metal Pt-like activity achieved by the transition metal oxides electrocatalysts based on oxides matured and cooperative with coupling metal oxides could be considered as a desired substitute electrocatalysts to change Pt/C based nano composite materials. Herein, un-noble the metal oxides of hetero structure consisting of Co3O4/MoS2 based-electrocatalysts nanocomposite material. The desirable out-comes show that Co3O4/MoS2 composite material providing extraordinary efficient HER kinetics activity in different experimental designs. The Co3O4/MoS2 based electro-catalyst increases the best activity of HER kinetics performance especially measured in 1 M KOH solution condition and offers an influential interfacing engineering strategy at very minute over potential of 348 mV evaluated and small Tafel slopes 46 mV/dec for HER performance. This work elucidates interest for efficient electrocatalysts for a broader range of scalable applications in the development of renewable energies, the functional materials such as solar cells, lithium sulphur-batteries and energy chemistry advancing. •A hot & novel method carried out to report the best performance of Co3O4/MoS2 based electrocatalyst.•The electrocatalyst exhibits a very favourable HER with a Tafel slope of 46 mVdec−1 & overpotential of 348 mV evaluated.•The rapid charge transfers and high conductivity of Co3O4/MoS2 due to low band gap is reported.•A small Tafel slope of 46 mV achieved to Co3O4/MoS2 electrocatalyst in alkaline media.
