Abstract Te‐MoTe 2 ‐MoSe /ZnO S‐scheme heterojunctions are engineered to ascertain the advanced redox ability in sustainable HER operations. Photo‐physical studies have established steady state transfer of photo‐induced charge carriers whereas an improved dynamics realized by state‐of‐art ultrafast transient absorption and irradiated‐XPS analysis optimized 5wt% heterostructure. 2.5, 5, 7.5wt% photocatalysts (2.5MTMZ, 5MTMZ 7.5MTMZ) exhibited 2.8, 3.3, 3.1‐fold higher performance than pristine ZnO with marvelous apparent quantum efficiency 35.09%, 41.42% 38.79% at rate 4.45, 5.25, 4.92 mmol/g cat /h, respectively. Electrochemical water splitting experiments manifest subdued 583 566 mV overpotential values 2.5MTMZ heterostructures achieve 10 mA cm −2 current density for HER, 961 793 OER, For photocatalyst, lifetime kinetic decay interfacial step is evaluated be 138.67 ps as compared 52.92 bare ZnO.
