The preparation of inorganic nanoparticles (NPs) through wet chemical approaches is very attractive, as chemical differentiations permit fine control of the structure, the chemical nature and the morphology of the nanostructures. However, rationalization is limited, and among the various methods for synthesizing NPs in solution, only a few are easy to use, produce NPs of high crystallinity and quality and can be scaled up. The so-called ‘‘polyol process’’ is recognized as possessing these features after about three decades of development. The present chapter reviews the redox mechanism of polyols, summarizes main findings and concepts for the production of metals, metal oxides and bimetallic nanostructures, and aims to provide the advantages but also the limitations that the polyol synthesis bears.
