N2 - Mesoporous nanostructured zinc sulfide was prepared by the hydro or solvothermal method using synthesized Hydrozincite as a novel zinc precursor. ZnS from annealing ZnO and zinc nitrate as zinc sources was also investigated. Synthesized Hydrozincite, ZnO and the ZnS samples were characterized by XRD, UV–vis diffuse reflectance spectroscopy and FTIR analysis. The morphology and textural properties of the ZnS materials were investigated by SEM and N2 adsorption-desorption, respectively. The photocatalytic properties of the ZnS materials were evaluated in the photocatalytic production of H2 using a methanol-water solution at pH 6 (natural) under UV light irradiation. For the unique active mesoporous ZnS, an additional chemical stability test varying the pH solution (acid or alkaline media) using four reaction cycles was carried out and selected spent ZnS was characterized. The photoactiviy of synthesized mesoporous ZnS from Hydrozincite by solvothermal method was discussed as a function of the presence of ethylenediamine linked to ZnS.
