“…Another solution is to use semiconductors with a narrower bandgap. Many other kinds of semiconductors are deposited onto the graphene such as SnO 2 , 88 AgX, 89,90 InNbO 4 , 91 Ag 3 PO 4 , 92 ZnO, 93,94 Bi 2 WO 6 , 95,96 CuS, 97 ZnS, 98 CdS, 99 etc. For example, γ‐Bi 2 WO 6 deposited graphene composite showed excellent photodegradation performance under visible light (Figure 3B,C), after 2 h reaction, over 80% MB was degraded 95 .…”

Solar‐powered water purification is able to gain freshwater from nonedible water by harnessing inexhaustible and pollution‐free sunlight energy, which is undergoing booming development to address the global water shortage. Due to the fascinating properties, numerous graphene‐based materials were devoted to the solar‐powered system from interfacial solar‐steam generation, towards solar pollutants degradation and even atmospheric water harvesting. Therefore, manipulations on graphene including chemical regulation and structural engineering were first introduced in this review, followed by the recent advancements in three main aspects of graphene‐based solar‐powered water purification concerning rapid steam generation, efficient pollutants degradation and significant atmospheric water harvesting. And the relationships between the designs of the materials with water purification performances were discussed in detail. Finally, a summary of challenges as well as the corresponding possible solutions were also suggested, aiming to provide scientific and technical inspirations to the flourishing solar‐powered water purification based on graphene functional architectures

“…Wastewater loaded with toxic, non-biodegradable organic pollutants represents a real problem, both for aquatic environments and for human life and development. Industrial wastewater originates mainly from the textile industry, but also from the plastics, paper, food, and cosmetic industries, due to the large amount of water used in the various technological stages, especially during the dyeing process [ 1 ]. It has been estimated that the wastewater from textile production contributes approximately 20% of the total industrial polluted water [ 2 ].…”

“…The presence of a very small concentration of organic dyes in water (less than 1 ppm for some dyes) may have serious consequences for the environment, but more for the population health, such as skin and eyes irritations, respiratory and gastric tracts affections, quadriplegia, tachycardia, tissue necrosis, and cancer [ 1 , 2 , 3 , 4 ].…”

“…), biological (biofiltration, biological nitrification–denitrification, bioremediation, aerobic/anaerobic, biosorption, membrane bioreactor—MBR, microbial fuel cell, etc. ), and chemical (ion exchange, electrolysis, ozonation, photolysis, sonolysis, photo-Fenton, and chemical, photo-, electro-, and photoelectrocatalysis) have been developed for removing organic pollutants from wastewater [ 1 , 2 , 7 , 9 , 10 ]. Currently, since individual techniques do not effectively remove pollutants from wastewater, hybrid technologies have been developed that are sustainable, stable, and more efficient, both in terms of pollutant degradation and in energy-saving.…”

The continuous growth of the world population has led to the constant increase of environmental pollution, with serious consequences for human health. Toxic, non-biodegradable, and recalcitrant organic pollutants (e.g., dyes, pharmaceuticals, pesticides) are discharged into water resources from various industries, such as textiles, leather, pharmaceuticals, plastics, etc. Consequently, the treatment of industrial wastewater, via a sustainable technology, represents a great challenge for worldwide research. Photocatalytic technology, an innovative technique based on advanced oxidation process (AOP), is considered a green technology with promising prospects in the remediation of global environmental issues. In photocatalysis, a very important role is attributed to the photocatalyst, usually a semiconductor material with high solar light absorption capacity and conductivity for photogenerated-charge carriers. Zinc sulfide (ZnS), as n-type semiconductor with different morphologies and band gap energies (Eg = 3.2–3.71 eV), is recognized as a promising photocatalyst for the removal of organic pollutants from wastewater, especially under UV light irradiation. This review deals with the recent developments (the last five years) in ZnS nanostructures (0D, 1D, 3D) and ZnS-based heterojunctions (n-n, n-p, Z scheme) used as photocatalysts for organic pollutants’ degradation under simulated (UV, Vis) and sunlight irradiation in wastewater treatment. The effects of different synthesis parameters (precursors’ type and concentration, capping agents’ dosages, reaction time and temperature, metal doping, ZnS concentration in heterostructures, etc.) and properties (particle size, morphology, band gap energy, and surface properties) on the photocatalytic performance of ZnS-based photocatalysts for various organic pollutants’ degradation are extensively discussed.

“… 8 However, the big challenge is the development of efficient catalysts, which simultaneously possess adsorption and catalytic abilities toward organic dyes. At present, different photocatalysts such as rGO/CuS, 9 chitosan/ZnO and chitosan/Ce–ZnO composites, 10 nZVI/BC, melon/TiO 2 , 11 diatomite/NiO composite, 12 and multicopper BSA-Cu complex 13 have been developed and used for efficiently removing and photodegrading MG. However, these nanomaterials or nanocomposites, which were prepared using the fussy preparation method, only demonstrate the sole ability, for example, adsorption or catalytic performance.…”
