Description:
Microwave-assisted combustion synthesis of porous nanocrystalline titania and carbon coated titania is reported using dextrose as template and the product was compared with the one obtained using conventional heating furnace. Out of three compositions viz., 1:1, 1:3, and 1:5 (metal:dextrose), 1:3 favors formation of consistent porous structures. The samples were then characterized using scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive X-ray analysis (EDX), X-ray diffraction (XRD) and X-ray mapping. This general and eco-friendly method utilizes a benign natural polymer, dextrose, to create spongy porous structures and can be extended to other transition metal oxides such as ZrO2, Al2O3 and SiO2.
