An efficient Ag-nanoparticle embedded semi-IPN hydrogel for catalytic applications

Abstract

Silver nanoparticle embedded semi-IPN hydrogels based on a combination of poly(acrylamide) and poly(aspartic acid) for catalytic application.

Synthesis of Ag decorated TiO2 nanoneedles for photocatalytic degradation of methylene blue dye

“…The findings, besides the TiO 2 species, demonstrate the existence of Ag 3d 3/2 and 3d 5/2 at BE of 374 eV and 367.5 eV in the XPS spectrum of the Ag-TiO 2 sample, showing that Ag has been effectively grown on the surface of TiO 2 , which is comparable to FESEM photographs. These results in consistence with earlier reported results [58].…”

Temperature responsive hydrogel magnetic nanocomposites for hyperthermia and metal extraction applications

“…The free network spaces present between the hydrogel networks stabilize the nanoparticles that are formed in the hydrogel network. The in situ reduction of metal ions and the stabilization of particles can be explained as follows: (1) the metal ions are attached to reactive sites of hydrogel networks, and larger amounts of metal ions are embedded in the network spaces of hydrogels; (2) the metal ions can be converted into nanoparticles by the action of NH 3 and (3) the resulting nanoparticles are well stabilized throughout the hydrogel network interspaces [17]. Scheme 1 illustrates the formation of magnetic nanoparticles embedded in the swollen NIPAM hydrogel composites.…”

Poly(aspartic acid) Biohydrogel as the Base of a New Hybrid Conducting Material

“…Thus, PASP hydrogels offer potential advantages over other conventional anionic hydrogels, becoming a promising choice for specific biomedical applications [ 28 ]. Despite this, PASP-based hydrogels have not been extensively used for the formulation of conductive composites but rather have been used in a secondary manner, e.g., mixed with silver nanoparticles for its catalytic effect [ 29 ] and to incorporate magnetic properties from Fe 3 O 4 particles [ 30 ].…”
