Synthesis and characterization of gold nanoparticles supported on zinc oxide via the deposition-precipitation method

Gold nanoparticles supported on zinc oxide nanoparticles were synthesized at several pH levels via the deposition-precipitation (DP) method. The effects of pH on gold loading, particle size, and particle size distribution on the support were studied at the iso-electric point (IEP) as well as below...
