Using potentially harmful substances and byproducts have long been a problem in nanotechnology. Green synthesis uses techniques and materials that pose no risk to people and the environment. The electrochemical approach may be included in the green synthesis process. The major goal of green electrochemical synthesis is to use non-toxic electrolytes, safe chemical solvents and microbial root. Most researchers have employed electrodeposition and other straightforward electrochemical methods to create nanomaterials since they are such environmentally friendly electrochemical processes. In order to get closer to our goal of sustainable development, more researchers need to work using this eco-friendly methodology. This review paper focuses on the recent advances in the green synthesis of nanomaterials harnessed by electrochemical methods.
