Abstract

This review describes some of the fascinating advances in the field of chemoselective hydrogenation of α,β-unsaturated aldehyde to unsaturated alcohol over nanomaterials that have emerged in recent years. The examples described are categorized into three main sections, according to the research approach applied, including the size/shape/composition control of the metal nanoparticle catalysts, the employment of novel nanosized inorganic materials, and the design/selection of stabilizer/solvent for the synthesis and dispersion of nanoparticle catalysts. The interplay between various parameters and the relevant catalytic properties of NP catalysts are discussed and possible future research trends are highlighted.
