(a,b) CZTS NPs, hybrid CZTS–A5 nanocomposites, and TiO2 (anatase) photocatalyzes the water–splitting H2 generation for 10 h using ethanol as a sacrificial agent under full spectrum light (the slopes associated with the hydrogen reaction rate simulations are 0.613, 0.414, 0.374, 0.274, and 0.177 mmol/g/h, respectively); (c) The photocatalytic activity of CZTS, CZTS–A5, and TiO2 (anatase) with the existence of ethanol as a sacrificial agent for 10 h; (d) Cyclic test of H2 generation in CZTS–A5 samples under full spectrum light irradiation; (e) Chopped linear sweep voltammetry (LSV) curve; and (f) chrono amperometry data plot of CZTS, CZTS–A5, and TiO2 (anatase) samples observed under the bias voltage of 1.5V (vs. RHE, the electrolyte is 0.5 M Na2SO4, pH = 6).
