The global manufacturing sector heavily relies on the textile industry, yet the widespread utilization of synthetic dyes within this sector has raised serious environmental apprehensions, notably regarding wastewater contamination. The release of untreated wastewater containing residual dyes poses a significant risk to both aquatic ecosystems and human well‐being. In reaction to this issue, considerable efforts have been made to develop efficient and sustainable methods for the removal of textile dyes from wastewater. This comprehensive review paper furnishes in‐depth literature information covering various aspects of dyes, including their classification, toxicity effects, and evaluation of recent advancements in dye removal technology, emphasizing their advantages, limitations, and future potential. Various strategies are covered, including physical, chemical, and biological methods. Physical techniques like adsorption, filtration, and membrane technologies are contrasted with chemical approaches such as coagulation, precipitation, and advanced oxidation processes. Biological methods include the utilization of micro‐organisms, fungi, and enzymes to break down or metabolize dye compounds. Key considerations in the critical analysis include the efficiency, cost‐effectiveness, and scalability of each method. This review focuses on enzyme breakdown (biological) and adsorption (physical) color removal procedures, which are currently considered the most effective. It also proposes the utilization of a composite adsorbent, anticipating enhanced efficiency and faster removal of dyes through this technique.

Wastewater treatment and management have been hot topics for the past three decades. Water reuse can help to alleviate the problems of water shortage and wastewater treatment in practice. Water can be used for household uses once the organic contaminants are removed. In this research, bare MoO3 and Ce‐doped MoO3 are fabricated using a straightforward hydrothermal method for wastewater treatment. The different analytical techniques are utilized to study the physiochemical features of all the synthesized products. Rhodamine B (RhB) is reduced photocatalytically under exposure of visible light to ascertain the possible capacity. The photocatalytic results suggest that the photoreduction of RhB with 2% Ce‐doped MoO3 exhibits a greater photocatalytic activity of 91.83% than the pure and other doped materials. The kinetic study of 2% Ce‐doped MoO3 displays the greater rate constant of 0.0163 min−1 and a lower Rct value of 0.95 Ω. The research indicates that the doping approach is a very effective way to decrease the bandgap and boost RhB's photocatalytic reduction. Other environmental and water‐related problems can be solved using Ce‐doped MoO3's improved physical and structural characteristics.

“…[4,5] Among the semiconducting metal oxides studied over the years, titanium dioxide (TiO 2 ) is widely used as photocatalytic materials for environmental applications owing to its high activity, chemical stability, robustness against photo corrosion, low toxicity, low cost, and sustainability. [6,7] Due to rapid electron-hole recombination, photocatalysis is limited. To solve this problem, semiconducting photocatalysis can be decorated with different noble metals like Au as electron sinks.…”

A novel catalyst for dye degradation was fabricated through attaching Au9 nanoclusters (Au9 NCs) to N functionalized mesoporous TiO2 (NMTiO2). The NMTiO2 was created through chitosan‐assisted soft templating resulting in a N terminated surface preventing the agglomeration of the Au9 NCs adsorbed surface and enhancing the overall loading with Au9. The calcination atmosphere influenced the surface properties of the NMTiO2 and its capability to adsorb the Au9 NCs. The photocatalytic effectiveness of these materials was probed through methyl orange (MO) dye degradation. The black coloured Au9/NMTiO2 catalyst is highly effective to completely degrade MO dyes within 20 minutes due to its large reaction constant (0.176 min‐1). Parameter interactions for the dye degradation process were explored using response surface methodology (RSM) and the dependency of MO degradation on the affecting parameters was evaluated based on the statistical analysis and 3D plots.This article is protected by copyright.
