Abstract
  Copper oxide nanoparticles are prepared adopting green synthesis route by using Aloe vera plant extract instead of synthetic and polymeric stabilizing agents in mild alkaline aqueous conditions. The synthesised CuO nanoparticles (CuO nps) are characterised by Powder XRD and HR-TEM measurements. Using ...  Read More

Abstract
  Photocatalysis mediated by metal nanoparticles is emerging as an effective method for removal of hazardous dye pollutants in natural aquatic bodies. Nanoparticles of Cu, Ni and Ag were synthesized by chemical method using PEG and PVP polymers as capping agents. Experimental photocatalyis was carried ...  Read More
