The photocatalytic properties of reduced graphene oxide decorated ZnS nanocomposite was employed for photodegradation of phenol red as a chemical agent in water. ZnS nanocomposite was synthesized by hydrothermal method. Reduced graphene oxide decorated ZnS nanocomposite was produced by pulsed laser ablation of graphite bulk in the solution of ZnS nanocomposite. Variety of spectroscopic and imaging diagnostics including X-ray diffraction (XRD), UV-Vis absorption spectroscopy, transmission electron microscopy (TEM), and scanning electron microscopy (SEM) were used to characterize the synthesized nanostructures. Water treatment was carried out in a closed handmade reactor. The concentration of the phenol red pollutant as the chemical agent, was extracted from the absorption spectra of treated water. Dependence of the behaviors of phenol red dye on the pH of the medium was studied in detail. Effects of UV radiation intensity, treatment time, pH of the polluted water, and aging on the efficiency of the treatment were investigated. Results show that even in the dark condition rGO-ZnS nanocomposite is an effective material to remove phenol red pollutant from water. The highest efficiency of treatment after 120 minutes was achieved in neutral pH water. Furthermore, after 7 days, with nanostructures and without UV radiation, the removal process in the polluted water was continued.

The water pollution caused by the release of organic pollutants has attracted remarkable attention, and solutions for wastewater treatment are being developed. In particular, the photocatalytic removal of organic pollutants in water systems is a promising strategy to realize the self-cleaning of ecosystems under solar light irradiation. However, at present the semiconductor-based nanocatalysts can barely satisfy the industrial requirements because their wide bandgaps restrict the effective absorption of solar light, which needs an energy band modification to boost the visible light harvesting via surface engineering. As an innovative approach, pulsed laser heating in liquids has been utilized to fabricate the nanomaterials in catalysis; it demonstrates multi-controllable features, such as size, morphology, crystal structure, and even optical or electrical properties, with which photocatalytic performances can be precisely optimized. In this review, focusing on the powerful heating effect of pulsed laser irradiation in liquids, the functional nanomaterials fabricated by laser technology and their applications in the catalytic degradation of various organic pollutants are summarized. This review not only highlights the innovative works of pulsed laser-prepared nanomaterials for organic pollutant removal in water systems, such as the photocatalytic degradation of organic dyes and the catalytic reduction of toxic nitrophenol and nitrobenzene, it also critically discusses the specific challenges and outlooks of this field, including the weakness of the produced yields and the relevant automatic strategies for massive production.
