Preparation of magnetic attapulgite nanocomposite for the adsorption of Ag+ and application for catalytic reduction of 4-nitrophenol

Facile preparation of Ag/Ni(OH)2 composites with enhanced catalytic activity for reduction of 4-nitrophenol

“…28 And it is known that the catalytic reduction of 4-NP to 4-AP is an electron transfer process. 29 So EIS was carried out to investigate the electrontransfer resistance of the catalyst to further study the reduction reaction of 4-NP to 4-AP. In Nyquist diagram, a smaller arc radius means a more facile charge transfer process at the interface of electrode.…”

Facile synthesis of monodisperse functional magnetic dialdehyde starch nano-composite and used for highly effective recovery of Hg(II)

“…Magnetic organic-inorganic nano-composite with magnetic core and polymeric shell are caused great interest compared with other nano-materials due to its good compatibility and functionalization with other materials, and it also could prevent the agglomeration of magnetic nanoparticles by organic shell which served as surfactant or stabilizer (Zhang et al, 2013c;Mu et al, 2013). As the burgeoning materials, varies magnetic organic-inorganic nano-composites have been reported and shown remarkable potential in the field of heavy metal removal because their high surface area, enhanced active sites and abundant functional groups on the surface (Zhu et al, 2010;Musico et al, 2013;Wang et al, 2011).…”

Facile fabrication of functional cellulose paper with high-capacity immobilization of Ag nanoparticles for catalytic applications for tannery wastewater

“…With the rapid development of modern nanotechnology [32,33], silver [34], gold [35], and other nanoscale precious metal particles [36] have been widely used as nanocatalysts, which have aroused great interest. AgNPs have high catalytic activity and are widely used in the reduction and degradation of organic compounds [37,38]. However, virgin AgNPs tend to aggregate in the catalytic process, thus inhibiting its catalytic performance and practical application [39].…”
