CARBON DOTS SYNTHESIS AND ITS INTEGRATION INTO NANO FERTILIZER FORMULATIONS A PROCESS THEREOF

Abstract

Rapid population growth alerts the agriculture sector the need for increased agricultural productivity to meet the rising demand for food. Nanotechnology is an emerging field with a wide potential. Crop productivity, improved soil health, improved photosynthetic activity can be achieved by this new technology. Thus, the need to identify and develop a new material with a biodegradable precursor is a major concern for researchers today. So far, activated carbon obtained from the carbonaceous materials are used for adsorptive purposes. The reduced surface area of these materials limits the advantage of its usage. Thus, carbon dot having a comparatively higher surface area, when doped with TiO2 enhances its applicability as Nano fertilizer. Green synthesis of carbon dots from Oleifera moringa leaf extract, a natural biomass as the carbon precursor can be manufactured using hydrothermal carbonization. The biocompatibility property of carbon dots suggests it to be a preferred material for environmental issue.
