Webb13 okt. 2016 · The Raman peak positions of the two peaks at 418.3 cm −1 and 577.7 cm −1 shift in the investigated area linearly with the Fe 2 O 3 content. This correlation can be applied in, for example, estimating the Fe 2 O 3 content in sapphire or corundum in general and contributes in distinguishing sapphires from different origins. Webbα-Fe2O3的表面改性及其光电催化性能的研究. Ti-Fe2O3/Pi photocathode reaches 1.56 mA/cm2 at 1.23 VRHE, which is. significantly higher than that of Ti-Fe2O3 (0.92 mA/cm2) and pure. α-Fe2O3 (0.5 mA/cm2). The photoelectrochemical analysis shows that the. ultrathin Pi nanolayers can passivate the surface of Ti-Fe2O3, inhibit. charge ...
