Catalytic activity of bare and porous palladium nanostructures in the reduction of 4-nitrophenol

Abstract

The catalytic activity of bare and porous palladium nanostructures viz. palladium nanoballs (PdNBs) and palladium urchins (Pdurc) synthesized in surfactant based liquid crystalline mesophase have been investigated in the reduction of 4-nitrophenol.

The Chemical Properties of Hydrogen Atoms Adsorbed on M0‐Nanoparticles Suspended in Aqueous Solutions: The Case of Ag0‐NPs and Au0‐NPs Reduced by BD4−

“…This study focuses on M 0 ‐nanoparticles (M 0 ‐NPs). These processes include, for example, electrochemical processes, photochemical processes, catalytic reduction processes including reductions by BH 4 − , hydrogen atom transfer processes, water reduction by radicals, hydrogen splitting reactions, hydrogen spillover processes, hydrogen storage, etc. In aqueous media, the equilibrium reaction: …”

The Chemical Properties of Hydrogen Atoms Adsorbed on M0‐Nanoparticles Suspended in Aqueous Solutions: The Case of Ag0‐NPs and Au0‐NPs Reduced by BD4−

“…Hydrogen atoms bound to metal surfaces are involved in avariety of important chemical processes.T his study focuses on M 0 -nanoparticles (M 0 -NPs). These processes include,f or example,e lectrochemical processes, [1][2][3][4][5][6][7] photochemical processes, [8][9][10] catalytic reduction processes [11] including reductions by BH 4 À , [12][13][14][15][16][17][18][19][20][21] hydrogen atom transfer processes, [22,23] water reduction by radicals, [24,25] hydrogen splitting reactions, [26,27] hydrogen spillover processes, [28][29][30][31][32][33][34][35] hydrogen storage, [36][37][38] etc.Ina queous media, the equilibrium reaction: is expected to occur, although k 2 is usually unknown. When M = Pt, k À2 is very fast, [39] whereas when M = Au, k À2 is very slow.…”

Bio-inspired synthesis of catalytically and biologically active palladium nanoparticles using Bos taurus urine

“…Generally the chemical methods are capable of voluminous production at low cost; however their drawback includes contamination from precursor chemicals, use of toxic solvents and generation of hazardous by-products. Bio-nanotechnology has emerged up as integration between biotechnology and nanotechnology for developing biosynthesis and environmentally friendly technology for synthesis of nonmaterial's and to check the biological effectiveness of the nanoparticles and to use in medicinal applications [15,16].…”
