Oxidation Of Glucose

A comprehensive review of the electroactive materials for non-enzymatic glucose sensing and sensing devices has been performed in this work. A general introduction for glucose sensing, a facile electrochemical technique for glucose detection, and explanations of fundamental mechanisms for the electro-oxidation of glucose via the electrochemical technique are conducted. The glucose sensing materials are classified into five major systems: (1) mono-metallic materials, (2) bi-metallic materials, (3) metallic-oxide compounds, (4) metallic-hydroxide materials, and (5) metal-metal derivatives. The performances of various systems within this decade have been compared and explained in terms of sensitivity, linear regime, the limit of detection (LOD), and detection potentials. Some promising materials and practicable methodologies for the further developments of glucose sensors have been proposed. Firstly, the atomic deposition of alloys is expected to enhance the selectivity, which is considered to be lacking in non-enzymatic glucose sensing. Secondly, by using the modification of the hydrophilicity of the metallic-oxides, a promoted current response from the electro-oxidation of glucose is expected. Lastly, by taking the advantage of the redistribution phenomenon of the oxide particles, the usage of the noble metals is foreseen to be reduced.

Acid properties of the oxides Al2O3, SiO2, TiO2, SnO2, Sb2O3, ZrO2 and ZrSiO4 were modified by the action of Lewis acids. The acids ( AlCl3, TiCl4, PCl5, SbF5 and P2O5) were deposited on the oxides by sublimation at 150, 250 and 350°C. The strength and number of acid centres of the prepared catalysts and their catalytic activity in hydrocarbon reactions were determined.

Properties of solid acid catalysts prepared by modification of oxides have been examined. The oxides Al2O3, SiO2, TiO2, SnO2, Sb2O3, ZrO2 and ZrSiO4 were impregnated by aqueous solutions of H2SO4, H3PO4, NH4F and NH4Cl, respectively, and calcined at 500, 650 and 800°C. For the so prepared catalysts, the strength and number of their acid centres and their activity for hydrocarbon reactions were determined.
