Abstract
A general overview of E-waste valorization toward nanomaterials design is provided. Cutting-edge materials including noble metal-containing samples are described, together with recent advances in E-waste, as sustainable source for catalysts design including electrocatalytic and photocatalytic applications. The present topic is, out of doubt, a very promising option to move into a more sustainable industry, allowing to reduce environmental issues related to E-waste accumulation as well as catalyst production costs.
