, and followed by washing with DDI water. The precipitation was dried at 110 °C for 12 h to get final SnO 2 catalyst. Catalyst characterization The specific surface areas of the samples were measured by

, its activity is limited by its regularly low surface area. This problem could be resolved by using an appropriate support. Supporting a metal oxide on the surface of another oxide was initially proposed to improve the catalytic activity of the active

qualitatively similar to that obtained in Mercedes-Benz water by Southall and Dill, and that they did not try to reproduce by means of their special application of 2D-SPT [ 10 ]. The decrease in solvent-excluded surface area on bringing in contact two disks
