Facile and controllable synthesis of AuCu aerogels for the enhanced degradation of 4-nitrophenol

Abstract Rationally designing bimetallic nanomaterials with high porosity and large specific surface area has an advantageous effect on enhancing catalytic performance. Bimetallic AuCu aerogels were successfully prepared using the in-situ reductions of Au and Cu precursors without any surfactant. Given its three-dimensional interconnected network and exposed crystal face, AuCu aerogels exhibited considerably excellent catalytic capabilities for the reduction of 4-nitrophenol than other reported Au-based catalysts.
