Green Synthesis of Gold Nanoparticles with Self-Sustained Natural Rubber Membranes
Figure 9
SEM microscopy analysis of solution used in synthesis of gold nanoparticles for 120 min reduction time using natural rubber (reducing agent) annealed at (a) 65°C, (b) 80°C, and (c) 120°C temperature. The solution is centrifuged to concentrate the amount of nanoparticles before SEM analysis.
