In Situ Construction of Ag/Ni(OH)2 Composite Electrode by Combining Electroless Deposition Technology with Electrodeposition

Abstract

The Ag/Ni(OH)2 composite electrode has been designed and in situ constructed on a copper substrate by combining electroless deposition technology with electrodeposition. The products can be directly used as a high performance binder free electrode. The synergistic effect between the Ag nanocubes (AgNCs) as backbones and the deposited Ni(OH)2 as the shell can significantly improve the electrochemical properties of the composite electrode. Moreover, this in situ growth strategy forms a strong bonding force of active materials to the substrate, which can improve the cycling performance and lower the equivalent series resistance. The Ag/Ni(OH)2 composite electrode exhibits enhanced electrochemical properties with a high specific capacitance of 3.704 F cm−2, coulombic efficiency of 88.3% and long-term cyclic stability.

Core–shell and heterostructured silver–nickel nanocatalysts fabricated by γ-radiation induced synthesis for oxygen reduction in alkaline media

“…As reported in the literature, binding energies for Ag 3d in Ag-Ni(OH) 2 composites may shift between 0.2 eV to 0.55 eV towards higher energies with respect to those in a pure Ag. 54,55 Ni 2p 3/2 photoelectron lines exhibit a shoulder towards high BEs, which is characteristics of NiO. 56 The asymmetry of the peak arises from the partial overlapping of the multiplet splitting of NiO and its 2p 3/2 peaks found at 854.7 eV and 856.5 eV, together with its 2p…”

Facile Route to Effective Antimicrobial Aluminum Oxide Layer Realized by Co-Deposition with Silver Nitrate

“…The advantage of this process is that it does not require conductive substrates, as the metal is deposited from a bath that contains a source of the metal as a cation and a chemical reducing agent. Recently, this technique has often been used for the deposition of silver on polymeric [37][38][39][40] and metal [41] surfaces, on carbon nanofibers [42] and graphene flakes [43]. Otherwise, the electrodeposition process requires a conductive substrate and the application of a certain current density to achieve the deposition of silver.…”
