Copper and silver nanowires for CO₂ electroreduction

Abstract

Copper and silver nanowires have been extensively investigating as the next generation of transparent conductive electrodes (TCEs) due to their ability to form percolating networks. Only recently, they have been...

Versatile Applications of Silver Nanowire-Based Electrodes and Their Impacts

“…The chemical reduction method is one of the most widely used ways to synthesize AgNWs [ 14 , 15 , 27 ]. Silver ions are reduced in a solution such as water or ethanol using a reducing agent such as sodium borohydride or hydrazine ( Figure 2 ) [ 27 ].…”

“…The advantages of the chemical reduction method include its simplicity, low cost, and the quality of the produced AgNWs with a high aspect ratio [ 14 , 15 ]. However, the difficulty in controlling the size and shape of the synthesized AgNWs and the contamination with impurities limit their use in the industry [ 14 , 15 ].…”

“…AgNWs are cylindrical in shape with diameters in the order of tens of nanometers and lengths in the order of micrometers [ 12 , 13 ]. AgNWs can be synthesized through various methods, including chemical synthesis [ 14 , 15 ], electrodeposition [ 16 , 17 ], and physical vapor deposition [ 18 ]. Chemical synthesis methods, such as the polyol reduction process, are effective in producing high-quality AgNWs with high aspect ratios [ 14 , 15 ].…”

The electrical and optical properties of AgNW transparent electrodes are significantly dependent on the aspect ratio of individual AgNWs and the density of the deposited networks [ 14 , 15 ]. To achieve high electrical conductivity with optical transparency, long and thin AgNWs are required because they can make sufficiently percolated networks with a low density of AgNWs that provide sufficient vacant spaces through which light can transmit without a severe reflection at the surface of AgNWs [ 14 , 15 ].…”
