“…Palladium proved more suitable over silver and platinum and as expected from the stereochemical point of view the longer alkyl chains slowed the diffusion of the bulky pollutant [113]. The formation of bimetallic Pd/Au nanoparticles into PAMAM-OH G6 produced an additional successful suggestion for methyl orange degradation that established the excellent potential of Pd NPs [114].…”

Radially polymerized dendritic compounds are nowadays an established polymer category next to their linear, branched, and cross-linked counterparts. Their uncommon tree-like architecture is characterized by adjustable internal cavities and external groups. They are therefore exceptional absorbents and this attainment of high concentrations in their interior renders them ideal reaction media. In this framework, they are applied in many environmentally benign implementations. One of the most important among them is water purification through pollutant decomposition. Simple and composite catalysts and photo-catalysts containing dendritic polymers and applied in water remediation will be discussed jointly with some unconventional solutions and prospects.

“…The catalytic degradation of methyl orange results in the formation of sulfanilic acid and aromatic amines, − degradation of methylene blue results in leucomethylene blue, ,,, and that of 4-nitrophenol results in 4-aminophenol. − The byproducts of the catalytic degradation are colorless and have various industrial and medicinal applications, although toxic in higher amounts. ,,− ,− ,− This suggests that the processed water can be utilized by industries for the manufacturing of commercially relevant products . The reaction kinetics were monitored using UV–vis spectroscopy.…”

Removal of organic pollutants from industrial wastewater is of significant importance in wastewater treatment. Here, we present a highly efficient composite membrane composed of bacterial nanocellulose (BNC) embedded with mesoporous polydopamine (mPDA) and decorated with palladium (Pd) nanoparticles. The Pd-mPDA-BNC membrane is synthesized through simple and scalable process involving the in situ incorporation of mPDA nanoparticles into BNC matrix during its bacteria-mediated growth followed by in situ growth of Pd nanoparticles. The Pd-mPDA-BNC membrane exhibited high efficiency (above 99%) in removing cationic, anionic, and neutral dyes over a wide range of concentrations, and pH, and over multiple cycles of reuse. The synergistic effect of adsorption on mPDA nanoparticles and catalytic degradation by Pd nanoparticles enabled the simultaneous removal of multiple contaminants through a simple membrane filtration process. Furthermore, the Pd-mPDA-BNC membranes exhibited significantly higher water flux compared to commercially available ultrafiltration membranes with the same range of pore size, making them highly attractive for wastewater treatment.
