从图2-2(b)可以看出TiO2、TiO2-SnO2和TiO2-ATO

It can be seen from Figure 2-2 (b) that TiO2, TiO2-SnO2 and TiO2-ATO have no obvious absorption peaks of carbon-containing groups, and TiO2, TiO2-SnO2 and TiO2- prepared from Figure 2-3 It is proved that there is no Me─O─C fitting peak in the C 1s photoelectron spectrum of the ATO sample.

From Figure 2-2(b), it can be seen that TiO2, TiO2-SnO2 and TiO2-ATO have no obvious characteristic absorption peaks of carbon-containing groups, and can also be demonstrated by the C1s of the C1s of TiO2, TiO2-SnO2 and TiOOO2 and TiO2-ATO samples.

From Fig. 2-2 (b), it can be seen that TiO2, TiO2-SnO2 and tio2-ato have no obvious characteristic absorption peaks of carbon containing groups. It can also be proved that there is no me-o-c fitting peak in the C 1s photoelectron spectra of TiO2, TiO2-SnO2 and tio2-ato samples prepared from Fig. 2-3.<br>
