Latest Patents

Al-Assiri holds a patent for a method involving chemical sensing and photocatalysis with silver nanoparticles and mesoporous silicon nanocomposite. The patent describes the synthesis of silver nanoparticles (AgNPs) and mesoporous silicon (PSi) nanocomposite, which is utilized effectively as a chemical sensor and photocatalyst. The PSi is prepared through a simple stain etching of silicon microparticles in an HF/HNO3 aqueous solution, followed by the deposition of AgNPs onto the stain-etched PSi using the immersion plating technique. This resultant nanocomposite has been successfully employed for enhanced electro-oxidation and quantification of ascorbic acid on a modified glassy carbon electrode. Additionally, it is used for the photo-reduction of hexavalent chromium (Cr(VI)) to trivalent chromium (Cr(III)) under direct visible light irradiation in the presence of citric acid.
