Anthemis xylopoda flowers aqueous extract assisted in situ green synthesis of Cu nanoparticles supported on natural Natrolite zeolite for N -formylation of amines at room temperature under environmentally benign reaction conditions

Pd nanoparticles synthesized in situ with the use of Euphorbia granulate leaf extract: Catalytic properties of the resulting particles

“…A mechanism of polyol oxidation has been shown in Figure 6. These are in agreement with our previous findings [19][20][21][22][23][41][42][43][44][45][46]. Figure 7 shows the UV-vis spectrum of in situ green synthesized Pd NPs using aqueous extract of Euphorbia granulate which the progression of the reaction, formation and stability of Pd NPs were controlled.…”

“…Phenolics could be adsorbed on the surface of metal nanoparticles, possibly by interaction through π-electrons interaction in the absence of other strong ligating agents. These properties have already been exploited for the preparation of Pd NPs, Cu NPs, Au NPs, Au/Pd NPs, TiO 2 NPs, CuO NPs, Pd/CuO in our previous studies [19][20][21][22][23][41][42][43][44][45][46]. A mechanism of polyol oxidation has been shown in Figure 6.…”

Green synthesis, characterization and catalytic activity of natural bentonite-supported copper nanoparticles for the solvent-free synthesis of 1-substituted 1H-1,2,3,4-tetrazoles and reduction of 4-nitrophenol

“…These results verified the successful synthesis of Cu NPs on bentonite. In the presence of the Thymus vulgaris extract as a reducing and stabilizing agent, the Cu 2+ ions convert to Cu NPs and immobilize on the surface of bentonite [ 6 , 20 , 30 – 33 ].…”

Phytochemical Process for the Functionalization of Materials with Metal Nanoparticles: Current Trends and Future Perspectives

“…Among them, Natrolite zeolite and HZSM‐5 are the commonly used supports for metal nanoparticles fabricated employing phytochemical processes. Nasrollahzadeh et al., performed the first research work on the functionalization of Natrolite zeolite surface with the Cu nanoparticles by using the aqueous extract of Anthemis xylopoda flowers as a reducing and stabilizing agent. The obtained functional zeolite showed excellent catalytic performance in N‐formylation of amines under solvent‐free conditions.…”
