Green synthesis of nanoparticles for varied applications: Green renewable resources and energy-efficient synthetic routes

This study presents an outline of the 12 principles of green relevance in nanomaterial synthesis. The goal of using green renewable resources is to protect the environment from negative effects, which can be achieved several main directions, including the choice of innocuous solvents, such as supercritical (SC) fluids or water, and/or additives ( stabilizers, capping, and reducing agents) such as polysaccharides, using alternative reaction circumstances, and the development of energy-efficient synthetic methods. This review shows how different green renewable resources routes are reducing the impact of chemical processes on the environment and how their benefit can be achieved in nanotechnology applications such as green energy.
