ZnO nanoparticles (NPs) were comparatively synthesized via precipitation and combustion techniques. The ZnO NPs synthesized via precipitation and combustion exhibited similar polycrystalline hexagonal wurtzite structures. The large crystal sizes of ZnO NPs were obtained from the ZnO precipitation in comparison with those from the ZnO combustion, while the particle sizes were in the same range. The functional analysis implied that the ZnO structures had surface defects. Moreover, absorbance measurement showed the same absorbance range in ultraviolet light. In the photocatalytic degradation of methylene blue, ZnO precipitation exhibited higher degradation performance than ZnO combustion. This was attributed to the larger crystal sizes of ZnO NPs, which provided an enduring carrier movement at semiconductor surfaces and reduced electron-hole recombination. Thus, the crystallinity of ZnO NPs can be considered an important factor in photocatalytic activity. Furthermore, precipitation is an interesting synthesizing method for preparing ZnO NPs with large crystal sizes.

The present scenario of water insecurity (poor availability and accessibility to clean and healthy water when needed) denotes the preponderance of environmental damage caused by effluents or waste runoff from industries, such as the dye and textile industries. The polluted waters have led to terrible and sonorous negative impacts on the ecosystem and econetworking, thus, urging for a sustainably suitable substitute to tackle and annul the noxious environmental constraint posse by the hazardous dye effluent. Several chemical and physical methods for treating dye effluent are now in use, but they are time‐consuming, expensive, and inefficient. Interestingly, nanoparticles have egressed as a superior answer for efficient dye removal and degradation, because of their chemical reactivity and exceptional surface characteristics. As a result, the use of metal nanomaterials in the treatment of dye runoffs has been thoroughly investigated. The study used major scientific databases such as SciFinder, Scopus, PubMed, Google Scholar, and Science Direct to conduct a comprehensive review of publicly available literature. Degradation, dye effluent, green metal nanoparticles, and water pollution were the keywords used to find scholarly papers. Efforts were made to figure out and explain the mechanism of dye effluent degradation, how long the degradation will take and how effective the use of plant biosynthesized metal nanoparticles for dye removal is. In addition, the role of bimetallic nanoparticles has also been investigated with remarkable feat from literature. The current level of knowledge about the mechanism and the use of plant biogenic metal nanoparticles in common dye effluent treatment is summarized in this paper.

Photocatalysis plays a crucial role in tackling environmental challenges by efficiently breaking down organic pollutants in water. This study highlights the significant contribution of 2D materials in advancing photocatalytic technology for sustainable environmental remediation. It explores various aspects of photocatalytic processes, including important performance metrics such as reaction rate, quantum yield, space yield, energy consumption, and figure of merit. The main focus is on 2D materials‐based structures, such as metal oxide supported on graphene and graphene oxides, MXene, or MoS2 (referred as 2D‐MO NPs), as well as more complex nanocomposite configurations (referred as 2D‐MO NCs). Furthermore, the research examines the complex interaction between compositional and operational factors that influence photocatalytic activity, as well as different photocatalytic mechanisms and active species. Finally, it addresses the current limitations of photocatalytic organic pollutants degradation for field applications and discusses the prospects of this technology.
