Facile fabrication, characterization and enhanced heterogeneous catalytic reduction of 4-nitrophenol using undoped and doped ZrO2 nanoparticles

Here, we successfully developed the undoped, Ni2+, Cu2+, and Zn2+ doped Zirconia nanoparticles (ZrO2 NPs) by a simple co-precipitation method at room temperature and characterized by various physicochemical measurement techniques to investigate their structure, morphology, and sizes of the particles. The bandgap energy values of doped and undoped ZrO2 NPs were estimated using optical absorption...

Glucomannan-mediated facile synthesis of gold nanoparticles for catalytic reduction of 4-nitrophenol

A facile one-pot approach for synthesis of gold nanoparticles with narrow size distribution and good stability was presented by reducing chloroauric acid with a polysaccharide, konjac glucomannan (KGM) in alkaline solution, which is green and economically viable. Here, KGM served both as reducing agent and stabilizer. The effects of KGM on the formation and stabilization of as-synthesized gold ...

In situ recyclable gold nanoparticles using CO2-switchable polymers for catalytic reduction of 4-nitrophenol.

CO(2)-switchable gold nanoparticles (AuNPs) were prepared by functionalizing AuNPs with CO(2)-switchable polymers. Their dispersion-re-dispersion in and separation from aqueous solution can be easily and reproducibly adjusted by CO(2) bubbling through and removal from the solution, enabling unique CO(2) controllable, efficient in situ recycling of NPs. As compared to non-functionalized AuNPs, t...

Synthesis of Small Silver Nanoparticles and Their Catalytic Activity in 4- Nitrophenol Reduction

This work is aimed at preparation of small silver nanoparticles (Ag NPs) with various sizes using two-step preparation method. The silver bromide nanoparticles were prepared in the first step and they were reduced to metal silver nanoparticles in the second step. Size of prepared silver nanoparticles was controlled by using of several modifiers. Two surfactants (SDS and Tween 80) and two natura...

Catechin-capped gold nanoparticles: green synthesis, characterization, and catalytic activity toward 4-nitrophenol reduction

An eco-friendly approach is described for the green synthesis of gold nanoparticles using catechin as a reducing and capping agent. The reaction occurred at room temperature within 1 h without the use of any external energy and an excellent yield (99%) was obtained, as determined by inductively coupled plasma mass spectrometry. Various shapes of gold nanoparticles with an estimated diameter of ...
