Green synthesis of perlite supported silver nanoparticles using Hamamelis virginiana leaf extract and investigation of its catalytic activity for the reduction of 4-nitrophenol and Congo red

Synthesis paradigm and applications of silver nanoparticles (AgNPs), a review

“…Recently, AgNPs synthesis by plants extract divert researchers' attention and continued to increase its synthesis from various plant extracts such as synthesis of AgNPs from Bunium persicum seeds extract [64], Hamamelis virginiana leaf extract [65], Carpobrotus acinaciformis extract [66], Psychotria nilgiriensis leaf extract [67], Rubus ellipticus leaf extract [68], Phyllanthus acidus L. fruit extracts [69], Ag/TiO 2 nanocomposite synthesis using Euphorbia heterophylla leaf extract [70], Ag/ zeolite nanocomposite using Euphorbia prolifera leaf extract [71], Ag nanoparticles using Tamarind fruit extract [72], AgNPs using Carpobrotus acinaciformis extract [66], Ag/RGO nanocomposite by use of Abutilon hirtum leaf extract [73], Euphorbia helioscopia linn as a green source for synthesis of silver [74], Ag and Au nanoparticles using Spinacia oleracea linn. Leaf extract [75], Ag nanocomposite using Euphorbia heterophylla leaf extract [76].…”

A Facile Green Reduction for Graphene‐Silver Nanocomposite Using Betel Leaf Extract for the Photocatalytic Degradation of Water Pollutants

“…Despite the fact that graphene and metal NPs are not good photocatalysts, the combination, i. e. graphene‐metal nanocomposites are better photocatalysts. Particularly the deposition of noble metals such as gold, platinum and silver on graphene substrate enhances the photocatalytic activity owing to the better light absorption capability (Vis and IR radiations), faster electron mobility of the generated photo electrons and delayed electron‐hole recombination process ,. Several such graphene based photocatalysts were reported till date.…”

Structure‐activity relationship of supported Au catalysts with high catalytic activity by modifying the inactive supports

“…Because Haruta et al found the preparation method of highly active gold nanoparticle catalyst on the active support surface in 1987, a large number, extensive and in‐depth of researches about nanoscale gold catalysts were published in the next 230 years . In recent years, with the consciousness improvement in energy crisis and environmental protection, there is more attention paid to energy, chemical industry, and environmental problems . Since we found that gold catalysts exhibited catalytic activity to CO oxidation at a low temperature, the applications of gold catalysts to solve energy and environmental problems have appeared substantially .…”
