Special effect of urea as a stabilizer in thermal immersion method to synthesis porous zinc oxide nanostructures
ZnO nanostructure was prepared by catalytic immersion method (90°C) with zinc nitrate hexahydrate (Zn(NO3)26H2O) as a precursors and urea (CH4N2O) as a stabilizer. Different molarity concentration ratio of Zn(NO3)26H2O to CH4N2O, 2: 1, 1: 4, 1: 6, and 1: 8 is used in this work. The effect of urea co...
