Characterization of gold nanoparticles augmented cellulosic microcapsules by alginate encapsulation method for p-nitrophenol degradation / Nurafadyla Jeman

The aim of this work was to synthesise and characterize the physical and chemical properties of the AuNPs and to investigate the feasibility of p-nitrophenol (PNP) degradation by AuNPs augmented cellulosic microcapsules in the catalytic reduction of PNP. The AuNPs was synthesized by using citrate re...
