Au–Cu–M (M = Pt, Pd, Ag) nanorods with enhanced catalytic efficiency by galvanic replacement reaction

Abstract

This work reports a general wet-chemistry method to produce Au–Cu–X (X = Pt, Pd, and Ag) trimetallic nanorods using galvanic replacement reaction with Au–Cu nanorods as the templates.

Deciphering the Kinetic Study of Sodium Dodecyl Sulfate on Ag Nanoparticle Synthesis Using Cassia siamea Flower Extract as a Reducing Agent

“…Also, an absorption eminence was found at 530 nm in the case of 0.5 mM, where the Ag NPs were mostly of flat hexagonal shape. 57 The uneven higher UV–visible absorption readings in the case of 1 mM could be due to aggregations and commencement of large-sized, irregular Ag NPs. 58 …”

Borohydride stabilized gold–silver bimetallic nanocatalysts for highly efficient 4-nitrophenol reduction

“…In particular, bimetallic gold/silver nanoparticles (AuAgNPs) provide an inexpensive alternative to monometallic AuNP catalysts while generally possessing higher catalytic activity for the reduction of nitroarenes. [16][17][18][19][20][21][22] Herein, we investigate a slightly modied Astruc method for the synthesis of monometallic AuNPs and AgNPs as well as bimetallic Au x Ag 1Àx NPs (where x ranges from 0.9 to 0.1 in 0.1 increments) using NaBH 4 as the sole reducing/stabilizing agent. Three distinct molar ratios of reducing agent to metal (denoted herein as R values; specically, R ¼ 2, 5, and 10) were used to create sets of monometallic/bimetallic NP solutions as shown in Tables S1-S3.…”

A review on recent approaches for designing the SEI layer on sodium metal anodes

“…When the metal cations dissolved in solvents are in contact with another solid metal that has a lower reduction potential, chemical replacement occurs between the two metals. [84][85][86][87][88] Generally, the electrolyte contains metal cations of the same element constituting the anode to mediate transport between the anode and cathode; however, if the metal cations are dissolved intentionally, such as Sn 2+ and Sb 3+ , chemical replacement is induced. 89,90 Zheng et al introduced SnCl 2 additives in a carbonate-based electrolyte to generate an Na-Sn alloy and the NaCl hybrid SEI layer (Fig.…”
