SnO2 nanoparticles are the materials that have many advantages physically and chemically, therefore they have been applied in many fields such as photocatalysts, gas sensors, dye sensitized solar cells (DSSCs) and lithium batteries which were all strongly influenced by the morphology, especially the formation of aggregates. This aggregates can be reduced by using the capping agents such as synthetic and natural compounds using the hydrothermal reaction. In this research, SnO2 nanoparticles were synthesized by green hydrothermal synthesis at relatively low temperatures using sucrose as the capping agent to reduce the aggregate formation. The effect of sucrose concentration as the capping agent on the SnO2 nanoparticles properties was examined using X-Ray Difraction (XRD) and Scanning Electron Microscope (SEM). The XRD pattern obtained, showed that the variation of sucrose concentration give a significant effect on the SnO2 nanoparticles properties. While the SEM analysis also showed that the sucrose concentration greatly affects the aggregates formation and the porosity of SnO2 nanoparticles. This result shows that the optimization of sucrose concentration in green synthesis of SnO2 nanoparticles could be used as an alternative way to control the crystallinity and morphology of SnO2 nanoparticles.
