“…It exhibited shape memory properties and good mechanical stability under wet conditions, and its decolorization activity was high as 5 × 10 4 Lm −2 h −1 . This study demonstrated the recyclability and stability of the 3D nanocellulose-based aerogel membrane after a continuous catalytic discoloration process was performed ten times [79,96,97]. In organic compound degradation, semiconductor nanomaterials are widely used as the photocatalyst.…”

Rapidly increasing industrialisation has human needs, but the consequences have added to the environmental harm. The pollution caused by several industries, including the dye industries, generates a large volume of wastewater containing dyes and hazardous chemicals that drains industrial effluents. The growing demand for readily available water, as well as the problem of polluted organic waste in reservoirs and streams, is a critical challenge for proper and sustainable development. Remediation has resulted in the need for an appropriate alternative to clear up the implications. Nanotechnology is an efficient and effective path to improve wastewater treatment/remediation. The effective surface properties and chemical activity of nanoparticles give them a better chance to remove or degrade the dye material from wastewater treatment. AgNPs (silver nanoparticles) are an efficient nanoparticle for the treatment of dye effluent that have been explored in many studies. The antimicrobial activity of AgNPs against several pathogens is well-recognised in the health and agriculture sectors. This review article summarises the applications of nanosilver-based particles in the dye removal/degradation process, effective water management strategies, and the field of agriculture.

“…Due to their accessibility, low price, and established medicinal properties, copper nanoparticles are of enormous significance. [4] Copper nanoparticles have a place with monoclinic structure framework. As a p-type semiconductor, [5] copper nitrate has a much larger optical band hole (2.43 eV) than mass Cu nanoparticles (1.85 eV).…”

One of the most recent areas of interest in current nanotechnologies and nanosciences is the use of biomaterials in the manufacturing of nanoparticles. More and more research is being carried out on environmentally friendly methods to create metal oxide nanoparticles (NP), with the intention of preventing any potential risks associated with harmful substances for a safe and healthy environment. In this study, Copper Oxide (CuO) is synthesized utilizing Opuntia ficus‐indica as the plant extract using a Microwave Combustion Technique (MCM) and its comparison against the Conventional Combustion Method (CCM) are investigated. The synthesized CuO nanoparticles were characterized using X‐ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FT‐IR), Scanning Electron Microscopy (SEM), and Energy Dispersive X‐ray Analysis (EDX) analysis. Photoluminescence spectroscopy was undertaken to acquire emission and absorption spectra and determine defects in the structures of all synthesized nanopowder samples. The antibacterial activity of the CuO nanoparticles was evaluated in‐vitro using gram‐negative and gram‐positive bacteria (Bacillus subtilis, Staphylococcus aureus). Enhanced anti‐bactericidal activity was shown against Gram‐negative bacteria compared to Gram‐positive bacteria. Through these findings, the use of CuO using Opuntia ficus indica extracts is hereby shown to be a cost‐effective and environmentally friendly alternative and that can be used in a variety of applications.
