N-doped graphene oxide nanomaterial: synthesis and application as controlled-release of urea for advancement in modern agriculture

Abstract

Controlled-release fertilizer plays a crucial role in advancing modern agriculture. One promising avenue of research is the utilization of graphene oxide (GO) for controlled-release fertilizer. Here, urea decorated GO (urea@GO) nanomaterial has fabricated through mechanical process and applied for enhance the releasing characteristics of urea by control study. From the experiment, it has seen the nanocomposite (urea@GO) extends the power of the nutrient release period to ≥ 10 h in aqueous media. Where the UV–Vis peak at 560–600 nm shifts towards 400–490 nm by the formation of N-doping. This original and innovative technology holds a significant development for potential crop production. One more advantage is the photochemical dissociation of by-products & residue of GO and the release of non-toxic & eco-friendly species, which are not harmful to crops as well as the health of the environment.
