“…The increase in the world population needs also to an increased health and care activities and drugs. Unfortunately, there are no balances between these activities and the increased world population and thus the pollution of water supplies is major global problem at this time (Segundo et al 2019;Ahmad Bhat et al 2020;Huang et al 2019) An important class of chemicals with wide applications in pharmacological, biological and industrial activities is anilineand anilinederivates.These chemicals have adopted wide uses for manufacturing of pesticides, dyes, cosmetics,medicines, synthetic polymers, rubber, etc.These also used intermediates for preparing of many chemical compounds ) Rappoport 2007 ;Akyuz et al 2006). Thus, high amounts of these aromatic amines have been discharged into the aquatic environments resulting in a high pollution of the water resources.…”

The ZnO supported on the ball-mill prepared clinoptilolite nanoparticles (CNPs) was prepared via an ionexchange process followed by the calcination process. The ZnO-CNP catalyst was brie y characterized by XRD, FTIR, and DRS techniques. The pHpzc value for the various ZnO-CNPs was about 7.1 that no changed with the ZnO loading. By applying the Scherrer equation on the XRD results, a nano-dimension was obtained for the catalyst. Band gap energy of the ZnO-CNP samples were estimated by applying the Kubelka-Munk equation on the DRS re ectance spectra. The supported ZnO-CNP sample was then used in the photodegradation of 2,4-dichloroaniline (DCA).The effects of the most important key operating factors on the degradation e ciency was kinetically studied by applying the Hinshelwood equation on the results. The ZnO-CNP catalyst with 2 w% ZnO showed the best photocatalytic rate in the optimal conditions of 0.75 g/L, C DCA : 15 ppm, and the initial pH: 5.8. Finally, HPLC analysis of the blank and the photodegraded DCA solutions at 180 and 300 min con rmed 74 and 87% of DCA molecules were degraded during these times.

“…Table 1 shows the dose-dependent antioxidant activity of Ni NPs. The extraordinary antioxidant potential of Ni nanoparticles can be attributed to the electrondonating character of the negatively charged nanoparticles surface, which may be responsible for free radical species or hydroxyl ion scavenging [31]. As a result, this study found that green-synthesized Ni NPs exhibited equivalent antioxidant activity to ascorbic acid against DPPH [32].…”

The catalytic activity of Ni NPs can be utilized to alleviate environment pollution caused by industrial effluents containing organic dyes. In the present work, a green method was employed for the synthesis of Nickel (Ni) nanoparticles using Polyphenolic rich Terminalia Chebula fruit aqueous extract and evaluated its catalytic activity against carcinogenic congo red dye along with antioxidant activity. The UV-Vis peak at 395 nm revealed the formation and monodispersed nature of nanoparticle. FTIR studies confirmed that polyphenolic and alkaloids were utilized in the formation of nanoparticles. The XRD established formation of Ni nanoparticles of FCC. SEM indicated the agglomeration of nanoparticles and TEM established the spherical shape with an average size about 6-8 nm. This study also evaluated the catalytic and antioxidant activities of green synthesized Ni NPs. Catalytic degradation of carcinogenic congo red dye completed within 20 mints, degradation of the congo red dye found to be first order kinetics, antioxidant activity against DPPH found maximum to 100 μg/ml and EC50 as 65.01.

“…In their study, the B. subtilis (MIC: 21.875 µg/ml) was the most susceptible organism, and K. pneumonia (MIC: 175 µg/ml) as well as P. aeruginosa (MIC: 175 µg/ml) were the least susceptible bacterial strains with respect to the action of NiO nanoparticles. Bhat et al [25] synthesized face-centered cubic structure of NiO nanoparticles with 30 nm average size by co-precipitation method. In their study, K. pneumonia and B. subtilis showed maximum zone of inhibition (15 mm) at 40 mg/ml concentration, and minimum inhibitory concentration 62.5 µg/ml.…”

Bacterial resistance to antibiotic treatment is a major emerging clinical and public health issue across the globe. Advancements in the field of metal oxide nanomaterials in the last few years have improved the potential of metal oxides in different applications. Metal oxides, of which, nickel oxide (NiO) is one, also possess antibacterial activities. This investigation was planned to synthesize NiO nanoparticles to study their antibacterial potential in comparison with bulk NiO and standard antibiotics at different concentrations. Synthesis and characterization of NiO nanoparticles was done by standard procedures. The antibacterial potentials of different compounds were determined at different concentrations against S. aureus and E. coli. The diameter of zone of inhibition showed that the antibacterial effect of NiO nanoparticles against S. aureus was better than E. coli at the same concentration. The concentration-dependent effect of NiO nanoparticles was observed from 0.125 to 128 µg/ml. The effect of NiO nanoparticles was markedly better than bulk NiO at all concentrations. Tetracycline and gentamicin did not show effect below 1.0 µg/ml and 2.0 µg/ml, respectively. The activity index and fold increase of NiO nanoparticles were both higher than 1 and positive, with respect to tetracycline, gentamicin and bulk NiO against S. aureus and E. coli at all the tested concentrations. In conclusion, the NiO nanoparticles seemed to be a more potent antibacterial agent than their bulk form, tetracycline and gentamicin, and in future, their applications may be extended in biomedical field and other areas to reduce microbial infections and incidences of antibacterial resistance.
