Heterogenous Nanocomposite Catalysts With Rhenium Nanostructures for the Catalytic Reduction of 4-nitrophenol [PDF]

Scientific Reports, 2021
Abstract Stable and efficient heterogenous nanocatalysts for the reduction of 4-nitrophenol (4-NP) has attracted much attention in recent years. In this context, a unique and efficient in-situ approach is used for the production of new polymeric nanocomposites (pNCs) containing rhenium nanostructures (ReNSs).
