Synthesis, Features and Solar-Light-Driven Photocatalytic Activity of TiO2 Nanotube Arrays Loaded with SnO2
In the present study TiO2 nanotube arrays (TNTs) were loaded with a post-transition metal oxide particles namely SnO2 via incipient wet impregnation method by varying its concentration (1.59 wt%, 2.25 wt% and 2.84 wt%). The photocatalytic activity of the prepared photocatalyst was evaluated for the...
