Abstract

A cost effective and industrially viable synthesis protocol is used to stabilize CuO particles with flake like morphology. The particle formation is predominantly thermodynamic in nature and can be explained using the concept of nucleation induced growth mechanism. When compared to other trendy hierarchical nanostructures of CuO, these particles return appreciably higher catalytic activity for the reduction of p-nitrophenol in presence of NaBH4 as a reducing agent. The pseudo first order catalytic reaction rate constant in CuO nanoflakes is 2 times higher than hollow or solid counterparts. The underlying reasons for the observed high reduction catalysis are presented.
