“…Conversely, the NP biofabricated process does not require the application of harmful surfactants or solvents, and it has infinitesimal after‐use toxicity and virtually zero secondary pollution production after degradation operation. This meritorious reduced toxicity in turn confers green synthesized NPs with admirable reusability and recyclability in the degradation of dyes, thus adding eco‐economic profit to the sustainable goal board 3,127 . For example, Yang et al 128 synthesized green Ag–Pt NPs with Crocus sativus L. extract and conducted reusability research on it for the degradation of MO.…”

“…Furthermore, in contrast to the traditionally fabricated NPs, the utilization of biological substances in synthesizing MNPs afforded improved hydrophilicity because of various architectural water‐loving (hydrophilic) functional groups (OH, C=O, COOH, NH 2 , and SH) available in the biogenic matrix employed 3,4 . This excellent hydrophilicity of green synthesized NPs is a big plus because of the fact that the degradation of dye contaminants occurs in an aqueous environment and highly hydrophobic degrading agents may not function or work effectively.…”

“…It is an essential source of life and survival for all living creatures and the main outlet of the freshwater bodies are rivers, lakes, ponds, and so forth, which are the primary source of water for mankind. Interestingly, humans drink about 0.03% of the entire freshwater that covers the earth's surface and are still unable to get desirable stress‐free freshwater 1–4 . Besides, according to Delanka‐pedige's team, 5 adequate availability and accessibility to clean and safe water is a strong indication that society is progressing 5 and this has made the United Nations recognize the importance of access to clean, affordable, and safe drinkable water as a fundamental right of all humans and have included it as Goal 6 of the United Nation's (UN) sustainable development goals (SDGs) 5…”

“…In recent times, several reviews 2,8,32,75–125 have been published on the photocatalytic degradation of various dye pollutants in an aquatic medium using different nanomaterials. However, only a few 2–4,77,81,82,86,91,96,102,123,124 focus on the biosynthesized NPs for the dye photodegradation application.

Water is the source of life. But unfortunately, 80% of wastewater is discharged into the aquatic body untreated globally, of which industry is responsible for 70% of such water abstraction through the discharge of pollutants like methyl orange. According to the WWAP, water pollution kills 100 million individuals, 2 million marine animals, and seabirds yearly, and by 2025, it is forecasted that ~1000 million inhabitants in arid zones will experience severe water crisis, and thus, the security of water has become focal outcry due to daily environmental pollution escalation caused by rapid growth in industries and population. Recently, biosynthesized nanoparticles as photocatalysts have answered the call for sustainable treatment of methyl orange dye effluent through photodegradation because of their efficient photoactivity, inexpensiveness, and eco‐benignness. In this review, photocatalytic‐degradation mechanism and pathways of methyl orange in the aquatic environment in the presence of •OH− and •O2− using green nanoparticles were mechanistically discussed. The highest degradation efficiency was found to be 100%, the final mineralization products were H2O and CO2, and the least degradation time taken was 2 min with silver nanoparticles being the most commonly used degrader and plant extracts being the most commonly employed bioreductant for the biosynthesis of nanoparticles.

Layered double hydroxides (LDHs) is a category of 2D materials that possess excellent physicochemical properties for enhancing photocatalytic (PC), electrocatalytic (EC), and photoelectrochemical (PEC) performances. However, pristine LDH encounters challenges like sluggish charge‐carrier mobility, high rate of electron–hole recombination, low conductivity, and tendency to agglomerate, making them unsuitable for practical applications. Therefore, modifications such as composite preparations, co‐catalyst integration, semiconductor coupling, and ternary heterostructure engineering have been explored to disclose new possibilities for LDHs in PC, EC, and PEC applications. In the realm of semiconducting materials aimed at enhancing LDH productivity, quantum dots (QDs) i.e., 0D materials have proven to be effective due to their advantages, including abundant reserves, affordability, and environmental friendliness. This review explores the role of QDs as interlayer support, co‐catalyst, mediator, semiconductor, and sensitizer in QDs@LDH heterostructures to achieve superior photocatalytic activities. These QD‐infused heterostructures also deliver improved EC and PEC water‐splitting performance coupled with long‐term stabilities. Additionally, this review delves into characterization techniques, intrinsic structural features, and designing of the QD@LDH heterostructures. Future scopes and challenges in constructing and cutting‐edge theoretical anticipations of QD@LDH are also discussed. This review may be a guiding light to a sustainable approach to outperform QD‐modified LDH for versatile catalysts.

IntroductionTribocatalysis, an emerging cutting‐edge technique that uses frictional mechanical energy to activate the catalytic operation of a reaction or material including nanomaterials has garnered the interest of the research community in recent times.AimThis study aimed to critically review original research works directed toward tribocatalytic degradation of various hazardous dye pollutants. Notably, in this review, various nanomaterials and their composites with outstanding tailored degradation profiles are explored for their tribocatalytic degradation efficiency for various dye pollutants. In addition, the effect of various operating factors that are of importance to engineers, industries, and investors for optimization purposes was pragmatically discussed. Also, the effect of electron trapping and radical scavengers alongside the mechanism of tribocatalytic degradation was empirically analyzed.ResultsFrom this work, it was found that the maximum tribocatalytic degradation efficiency was >80% in most cases at an optimum temperature of 20–40°C, time taken of 0.5‐48 hours, and stirring speed of 500‐1000rmp. It was discovered that magnetic stirring enhances the production of •OH, O2•, and h+ by the nanomaterials that are mechanistically responsible for the degradation of the dye pollutants. Also, it was revealed that expended tribocatalyst can be eluted mostly using H2O and can be reused up to 3–10 times while still sustaining degradation efficiency of >80% in most cases and this suggests the industrial scalability and eco‐friendliness potential of this approach.ConclusionIn the end, challenges and research gaps that can pave the way for method improvement and also serve as future research hotspots for researchers were presented.
