Mof-mediated magnesium oxide/carbon substrate for surface cleaning applications

Overview

This research proposes a MOF-mediated magnesium oxide/carbon nanocomposite designed for surface cleaning applications, particularly targeting fluid food containers such as those used for cola, juice, espresso, honey, and soup. Conventional cleaning of these containers often requires chemical detergents because fluid food residues, saliva contamination, and bacterial biofilms adhere stubbornly to vessel walls. The proposed nanocomposite aims to enable effective cleaning using only water, addressing both organic residue removal and bacterial contamination concerns in food-contact surfaces.

Technical specifications

Key features:

• Core-shell nanoparticle architecture combining magnesium oxide (MgO) nanoparticles with activated carbon derived from palm shell waste
• Single-pot synthesis process using MOF embedding: 10 g of activated carbon mixed with 50 mL of 0.025M magnesium oxide via drop-wise addition
• Thermal processing at 100°C for 12 hours to produce the final nano-MgO carbon composite
• Characterization methods including Scanning Electron Microscopy (Carl-Zeiss EVO 20, 25kV) for morphology and size distribution, X-ray diffraction (Shimadzu, Cu-Kα radiation at 1.54 Å) for phase analysis, and FTIR for functional group determination
• Self-cleaning mechanism driven by electrostatic and hydrophobic interactions between the nanocomposite surface and organic contaminants such as anthracene
• Ionic strength sensitivity validated across sodium chloride concentrations of 0.1, 0.3, and 0.5 M, demonstrating tunable adsorption behavior

Technology readiness level

This technology is currently at an early research and development stage. The nanocomposite synthesis method has been established and initial characterization has been performed. Future validation requires approximately 8 to 12 months of additional work, including optimization of component dosages (3 months), comprehensive characterization studies (3 months), and preliminary surface cleaning application testing (6 months) before a final product can be realized.
