This research explores the synthesis of Cu–Ni bimetallic nanoparticles (NPs) via KC 8 -driven reduction method at various refluxing time and aiming to evaluate their catalytic efficiency in the reduction of p-nitrophenol (p-NP) to p-aminophenol (p-AP). The incorporation of Ni into the Cu ...
Herein we report the performance of cheaper, more efficient and eco-friendlier chitin (CN) and chitosan (CS) biopolymers supported Cu nanoparticles (Cu NPs) catalysts (1.5 wt% Cu/CN) and (4.5 wt% Cu/CS) in the reaction model of para-nitrophenol (p-NP) reduction to para-aminophenol (p-...
