Thermophysical properties of hybrid nano fluids

Abstract

In this study, the ash from agriculture waste of bamboo leaves was used in the synthesis of silica nano particles followed by leaching and acid treatment. The required ash from agriculture waste (bamboo leaves) is subjected to sintered at 700 degree centigrade for 5 hours to eliminate residues from ash. The obtained powder was treated with 1M NaOH for leaching and then acid-treatment with 0.5 M H2SO4 to precipitate pure SiO2 nano particles powder. The synthesized silica were characterized by XRD, FTIR, SEM, PSA, ZETA POTENSIAL. And the synthesis of CuO-SiO2 hybrid nano fluid from the agriculture waste of silica.
