Abstract:The green chemistry synthesis has acquired importance in recent years because of the avoidance of hazardous byproducts. In the present work, black ZnO nanoparticles were synthesized by a combustion green chemistry process using coffee extract as a reducer agent and stabilizer of the reaction. The preponderance size distribution of the black ZnO nanoparticles was found between 15 and 30 nm. High-resolution transmission electron microscopy shows distorted regions from the atomic column, while the estimated energ… Show more
