“…34 Among nickel(II) compounds, Ni(OH) 2 has been demonstrated to be active for the photodegradation of azo dyes. 35,36 More importantly, Ni(OH) 2 exhibits good activity and reversibility during electrochemical oxidation into high valence state Ni compounds such as NiOOH. 24 This property suggests that Ni(OH) 2 can act as an electrocatalyst for the EOD of organic pollutants.…”

“…CdS is susceptible to producing photo-corrosion when the photo-catalytic, it is found that the synergic effects of CdS and ferrites can reduce the recombination probability of photo-generated electron-hole pairs and enhance the charge separation efficiency, leading to the higher photocatalytic performance and remarkable inhibited photocorrosion. Ferrite nanoparticles themselves have a strong magnetic property, which can be easily used for magnetic separation after degradation [19][20][21][22][23][24][25][26][27]. The present study describes the synthesis and characterization of nanosized cobalt hexaferrite particles using precipitation method.…”

In this work, firstly CoFe 2 O 4 nanostructures were synthesized via a simple precipitation method. Then cadmium sulphide and CoFe 2 O 4 -CdS nanocomposites were prepared by a fast chemical procedure. The effect of concentration, temperature and precipitating agent on the morphology and particle size of the magnetic products was investigated. The prepared products were characterized by X-ray diffraction, scanning electron microscopy, and Fourier transform infrared spectroscopy. Alternating gradient force magnetometer shows the super-paramagnetic and ferromagnetic property of the ferrite nanostructures. The photocatalytic behaviour of CoFe 2 O 4 -CdS nanocomposites was evaluated using the degradation of three azo dyes (acid black, acid brown and methyl orange) under ultraviolet light irradiation. The results show that nanocomposites have applicable magnetic and photocatalytic performance.

Facile Preparation and Highly Efficient Catalytic Performances of Pd-Cu Bimetallic Catalyst Synthesized via Seed-Mediated Method

With the rapid development of industry, the problem of environmental pollution has become increasingly prominent. Exploring and preparing green, efficient, and low cost catalysts has become the key challenge for scientists. However, some conventional preparation methods are limited by conditions, such as cumbersome operation, high energy consumption, and high pollution. Here, a simple and efficient seed-mediated method was designed and proposed to synthesize a highly efficient bimetallic catalyst for catalyzing nitro compounds. A Pd-Cu bimetallic composite (BCM) can be prepared by synthesizing the original seed crystal of precious metal palladium, then growing the mature nanocrystalline palladium and supporting the transition metal copper. Importantly, after eight consecutive catalytic cycles, the conversion of the catalyzed 2-NA was 84%, while the conversion of the catalyzed 4-NP was still 72%. And the catalytic first order rates of 2-NA and 4-NP constants were 0.015 s−1, and 0.069 s−1, respectively. Therefore, current research of nanocomposites catalyst showed great significance for serious environmental pollution problems and the protection of living environment, providing a new idea for the preparation of new bimetallic catalytic materials.
