ZnO is a semiconductor material that has important physical and chemical properties, which are frequently significantly enhanced by the addition of impurities, such as doping. A study structural properties pristine functionalized (i.e., doped with Antimony Tungsten) nanoparticles been conducted for photocatalyst-based degradation methylene blue (MB) dye under both Ultraviolet (UV) solar light. Authors have used 1% concentration dopant doping purposes. The synthesized materials were...
This review article provides useful information on TiO2 and ZnO photocatalysts their derivatives in removing organic contaminants such as dyes, hydrocarbons, pesticides, etc. Also, the reaction mechanisms of were investigated. In addition, impact adding metallic (e.g., Ag, Co, Pt, Pd, Cu, Au, Ni) non-metallic C, N, O, S) cocatalysts to structure photodegradation efficiency compounds was thoroughly studied. Moreover, advantages disadvantages various synthesis procedures nanocatalysts...
Every year, a huge amount of water is polluted by various sources, out which coal fly ash (CFA) one the major pollutants. CFA has large number toxic metals, reaches bodies coming in contact with or rain. Due to heavy-metal contamination, becomes unfit for drinking human beings, long term may cause several disorders. Thus, iron oxide nanoparticles (IONPs) recovered from waste, such as CFA, could be most promising material treating wastewater, due their low-cost, recyclable nature and magnetic...
Over the last decade there has been a huge increase in green synthesis of nanoparticles. Moreover, is continuous harnessing potential microorganisms for development efficient and biocompatible nanoparticles around globe. In present research work, investigators have synthesized TiO 2 NPs by Bacillus subtilis MTCC 8322 (Gram-positive) bacteria. The formation confirmation bacteria were carried out using UV-Vis spectroscopy, Fourier transforms infrared (FT-IR), X-ray diffraction (XRD), scanning...
The primary goal of this experiment is to examine the effectiveness Pseudomonas aeruginosa strain PAR as a rhizobacterium that promotes plant growth in mitigating negative effects fluoride-induced stress tomato ( Lycopersicon esculentum Mill.) plants. A total 16 rhizobacterial strains were tested for growth-promoting (PGP) attributes, with isolates S1, S2, and S3 exhibiting different characteristics. Furthermore, kinetics studies revealed these resilient fluoride (10, 20, 40, 80 ppm),...
In this study, natural clay minerals with green appearance were treated sulfuric acid. Mass percentage of acid (wt%), temperature (T), contact time (t) and liquid-to-solid mass ratio (R) are used as the prevailing factors that determine extent acid-activation. The values these range from 15–50%, 60–90 °C, 1.5–6 h 4–7, respectively. study has focused on structural changes well textural characteristics clay. Three activated samples prepared under different treatment conditions. characterized...
A magnetic polymer-based nanocomposite was fabricated by the modification of an Fe3O4/SiO2 composite with polypyrrole (PPy) via co-precipitation polymerization to form PPy/Fe3O4/SiO2 for removal Congo red dye (CR) and hexavalent chromium Cr(VI) ions from water. The characterized using various techniques including X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscope (SEM), vibration sample magnetometer, thermogravimetric analysis (TGA). results...
The laccase enzyme was successfully immobilized over a magnetic amino-functionalized metal–organic framework Fe3O4-NH2@MIL-101(Cr). Different techniques were used for the characterization of synthesized materials. Fe3O4-NH2@MIL-101(Cr) showed excellent resistance to high temperatures and low pH levels with immobilization capacity large activity recovery, due combination covalent binding adsorption advantages. long-term storage 28 days indicated retention 88% its initial activity, stability...
The fabrication of multifunctional nanomaterial for the adsorption different types pollutants is a challenge and could be solution many problems associated with wastewater treatment. This current study propose use crosslinked chitosan/nitrogen doped-graphene quantum dot nanocomposites (CS/NGQD) synthesized via glutaraldehyde as cross-linker to remove various including bacteria, proteins, fluoride, dyes, pharmaceuticals. was characterized using techniques (FT-IR, XRD, SEM, TEM, Raman...
