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 nature with a spherical shape having a mean particle size of 11±1 nm. It is found that biogenic NiO NPs is a highly efficient catalyst for benign one-pot preparation of pyridopyrimidine derivatives using
