“…The presence of silver will be increased the roughness (the inset in Fig. B) and antibacterial capability for ZAC, which was consistent with previous research results (Huang et al, 2020). Additionally, the mapping research demonstrates that C, O, Zn, and Ag were evenly dispersed on the surface of the biomass ber, suggesting that the composite of ZAC was synthesized.…”

“…However, the antibacterial ability of only ZnO is limited in practical applications. Thence, Huang et al synthesized Ag@ZnO-OAc NPs, the Ag@ZnO nanoparticles into the membranes to enhance the antibacterial performance of composite (Huang et al, 2020). Moreover, Dumée et al prepared a bio-antifouling membrane material, employing a novel cold spray technology to embed silver nanoparticles in the membrane to reduce biological pollution and bacteria in uence, to achieve the purpose of purifying wastewater, indicating that silver nanoparticles have great prospects in biological antifouling and antibacterial properties (Dumée et al, 2015).…”

Recovery of the tellurium from wastewater is signi cance for both industrial applications and sustainable development due to the adverse impacts emanating from environmental pollution and strategic values in the photovoltaic industry. Herein, this study presents the recovery of tellurium from wastewater by owerlike structure ZnO-Ag@cellulose (ZAC) composites. For adsorbent preparation, lignocellulose was rst extracted from waste wood debris by an alkaline extraction process. Then, the ower-like structure of ZAC composites were synthesized by a facile one-step hydrothermal method. The obtained materials are conducted under different parameters to investigate tellurium adsorption properties. The results indicate that the tellurium adsorption process is an exothermic reaction and ts well to the Freundlich model. Kinetic data are well described by pseudo-second-order model, indicating ZAC adsorption of tellurium is a chemical process. Besides, as-prepared ZAC exhibited excellent performance for tellurium elimination from wastewater with a maximum removal e ciency of 98.86%. The ZAC also shows outstanding antifouling performance in polluted environment and can still achieve the rate of 94.23% for tellurium. Moreover, the ZAC composite reveals high reusability and stability after six desorption-regeneration cycles. Importantly, the ZAC composite exhibits disinfection performance against E. coli and S. aureus with high killing e ciency. Therefore, this work not only demonstrates ZAC composite is e cient adsorbent with antifouling and antibacterial capability for tellurium recovery, but also provides an effective channel for promising candidates to decontaminate similar pollutants and practical applications of wastewater. Highlights 1. The ZAC composites were fabricated via a facile one-step hydrothermal method.2. The raw materials are extracted from waste wood debris using alkaline extraction process to extract lignocellulose.3. The prepared composite material has high antifouling and antibacterial ability for the adsorption of tellurium (IV). 4. The resulting composite material exhibits excellent performance, with a maximum removal rate of tellurium (IV) was 98.86%.5. The prepared adsorbent has excellent stability and reusable ability to remove tellurium in wastewater.

“…The ZnOA- and CdOA-InP QDs show vastly decreased peak intensities in both N 1s and Cl 2p spectra, implying removal of [OAmH + ]-Cl − ligands. Besides, both ZnOA- and CdOA-InP QDs observe a rise of intensities for O 1s with Zn-O or Cd-O binding and O-C-O/O-C=O from OA ligand ( Figure S6 a) [ 53 , 54 , 55 ]. The O-C-O/O-C=O binding in OA can also be found in C 1s spectra ( Figure S6 b) [ 56 , 57 ].…”

Bifunctional Metal Oleate as an Alternative Method to Remove Surface Oxide and Passivate Surface Defects of Aminophosphine-Based InP Quantum Dots

et al. 2022

The optical properties of indium phosphide (InP) quantum dots (QDs) are significantly influenced by their surface native oxides, which are generally removed by treating InP cores with hydrofluoric acid (HF). Besides the harmful health effects of HF, its etching may cause over-etching or QD size broadening, and surface oxidation can also reoccur rapidly. In the present study, a safer bifunctional metal oleate treatment was developed to simultaneously remove the surface oxide layer and passivate the surface defects for aminophosphine-based InP QDs. Compared to conventional HF etching, the bifunctional metal oleate was able to more efficiently remove the surface oxide of InP cores and effectively preserve the oxide-free surface, leading to a 20% narrower photoluminescence (PL) bandwidth after growing a ZnSe/ZnS shell. The metal oleate treatment is thus considered a greener and safer post-synthetic method to remove InP surface oxide and provide additional passivation to improve the optical properties of aminophosphine-based InP QDs, which could have potential in industrial mass production.

“…The overgrowth of bacteria mainly causes biofouling due to inhabitable environment in the wastewater. The formation of biofilms on the polymeric surface significantly decreases membrane lifetime, durability, and performance by blocking the surface’s active site and pores ( Huang et al., 2020 ) ( Aryanti et al., 2017 ). In addition, after a while, bioaccumulation initiates the release of bacteria, which is a serious concern for aquatic animals or humans ( Uddin et al., 2020 ).…”
