Algal magnetic nickel oxide nanocatalyst in accelerated synthesis of pyridopyrimidine derivatives

Abstract This research presents a novel biological route for the biosynthesis of nickel oxide nanoparticles (NiO NPs) using marine macroalgae extract as a reducing and coating agent under optimized synthesis conditions. XRD and TEM analyses revealed that phytosynthesized NiO NPs are crystalline in n...
