Photon-assisted water-splitting by photocatalytic materials is a green method to produce hydrogen as a clean fuel, and it is an environmentally friendly method due to the use of water and hydrogen burning and water regeneration. High efficiency, greenness, reproducibility, lower cost and the use of cheap natural equipment are the characteristics of this ideal and forward-looking method. In this research, lamp light shining on activated carbon-zinc sulfide-molybdenum disulfide nanocomposite was used to perform photolysis reaction to produce hydrogen from water. The method of producing activated carbon is a self-activating horizontal furnace system with a condenser, which is obtained from the raw material of mushrooms, and according to the results of porosity measurement, the temperature of 800 degrees Celsius is chosen for better porosity, more symmetrical distribution, and better specific surface area. The nanocomposite is obtained by dissolving and mixing the raw materials of ammonium heptamolybdate tetrahydrate, zinc nitrate.6 H2O, water, and porous activated carbon in one crucible and from sulfur powder in another crucible next to each other inside the furnace. Synthesized samples, with the help of X-ray diffraction analysis, diffuse reflectance spectroscopy, Fourier transform infrared spectroscopy, nitrogen absorption and desorption analysis (porosity), high resolution transmission electron microscope, high resolution field emission scanning electron microscope, elemental analysis (EDS and mapping), Raman spectroscopy, photocurrent analysis, Matt-Schottky technique, electrochemical impedance spectroscopy and linear sweep voltammetry were investigated. In the constructed arrangement for hydrogen production analysis, the amount of hydrogen production was measured as 15.8 micromol/h per 0.075 g of photocatalytic nanocomposite.
