Microwave-assisted Solution Combustion Synthesis of Nanostructured Zn2SnO4

A facile and rapid microwave-assisted solution combustion method was developed to synthesis to produce nanocrystalline Zn2SnO4 powder using dissolution of zinc and tin nitrate (as the oxidant) and glycine (as fuel) as the starting materials and water as solvent, then heating the resulting solution in a microwave oven. The study suggested that application of microwave heating to produce the homogeneous porous Zn2SnO4 was achieved in a few minutes. The structure and morphology of the as-prepared combustion products were investigated by means of XRD and SEM. Fron the XRD results, confirmed the formation of face-centered cubic spinel structural and the SEM results indicated the spherical surface characteristic of the products. The as-prepared powders have larger band gap energy (3.5 eV) and are described here.
