Preparation and Application of Core-Shell Nanocarbon-Based Slow-Release Foliar Fertilizer.

ABSTRACT: The application of nanotechnology offers a promising solution to improve fertilizer utilization efficiency by mitigating the losses and volatilization of conventional fertilizers, contributing to sustainable agriculture. In this study, a core-shell nanocarbon-based slow-release foliar fertilizer (CN@mSiO₂-NH₂@Urea@PDA) was synthesized using nanocarbon (CN) as the core, amino-functionalized mesoporous silica (mSiO₂-NH₂) as the shell, and polydopamine (PDA) as the coating layer. BET analysis revealed a 3.5-fold and 1.9-fold reduction in material porosity after PDA encapsulation, confirming successful synthesis. The controlled-release performance was enhanced, with a 24% decrease in the release rate and a prolonged nutrient delivery duration. Hydrop
