Nanoporous gold is basically produced by selective decomposition of silver from silver-gold alloys. Due to its excellent conductivity, high surface area to volume ratio, chemical inaction, physical stability, easily tunable pores and plasmonic properties, it has had a huge field in the field of nanotechnology. Square wave voltammetry is a type of linear potential sweep voltammetry that uses a combined square wave and potential sliding scale applied to a fixed electrode. Say no to plagiarism.

Nanoporous gold electrodes are prepared using electrochemical techniques. These techniques are simpler and stronger in nature. Various steps are involved in preparing the NPG solution. The procedure for preparing the solution involves the electrochemical deposition process. Next, the surface area and scanning speed of the NPG are calculated. Different formulas are used for calculation purposes. After these steps, lipoic acid (C8H14O2S2) is added to the NPG thread. Here lipoic acid is defined as an octanoic acid bonded to two sulfides, which is why it is sometimes called pentanoic acid. The last step involves the creation of the EDC and NHS solution. Experimental graphs and tables can be calculated and obtained through this experiment. Thus, this experiment is essential to determine the general properties of nanoporous gold. The nanoporous gold that is NPG is produced by selective corrosion which provides a model system for analyzing the electrochemical and mechanical properties of the nanomaterial. Nanoporous gold is produced by DE alloy, which is widely studied as an advanced catalyst for energy storage as a high surface area electrode. DE alloying refers to the removal of the less noble element from a solid solution by selective corrosion. In this experiment square wave voltammetry (SWV) is used to calculate both quantitative chemical analysis and the study of the mechanism and thermodynamics of chemical reactions. Hence, this is used as a tool that offers three main advantages over other electrochemical techniques. It requires less time per interval than older techniques such as pulse polarography. This SWV technique is used here to calculate the experiment accurately where one SWV scan can be recorded in less than ten seconds. Its frequency determines whether processes are based on fast or slow kinetics. Another technique explained in this experiment is cyclic voltammetry, which is generally preferred to square wave voltammetry for kinetic and mechanistic studies. However, the square wave voltammetry technique allows mechanistic and kinetic measurements in solutions. The entire procedure for preparing nanoporous gold is mentioned in this article. Although use in various processes such as, after the preparation of gold and silver solution. Electrochemical deposition in which three electrodes are used. The reference electrode (Ag-Ag cl), a working electrode (Au wire) and a counter electrode (pt wire or platinum wire) and then dealloying is performed to convert the alloy wires into nitric acid. Through this it is possible to obtain the three experimental tables of Cathodic and Anodic. You also get two graphs representing the current density (mA/cm2) versus the potential versus Ag*/Ag and the scan speed (m/Vs)., 2016).
