Dispersed copper oxide: A multifaceted tool in catalysis

► Chemisorptions-hydrolysis technique is a versatile method to prepare copper oxide nanoparticles on different supports. ► The use of different supports or catalyst activations (pretreatment) leads to different catalytic behavior. ► Dispersed copper catalysts can be used for hydrogenation reactions, deNOx SCR or acid catalyzed etherification.
