%X In
the present work, we accomplish the boosting of photocatalytic performance
by the synergistic effect of acid treatment and transition metal oxide
co-catalysts on molten salt rutile TiO2 nanorods. FT-IR
and XPS (oxygen deconvolution) results confirmed that the amount of
hydroxyl groups increased on the surface of rutile TiO2 nanorods (TO-NRs) after acid treatment. HR-TEM analysis revealed
fine dispersion of metal oxide on the surface of acid treated TiO2 nanorods (ATO-NRs). The photocatalytic activities of as-prepared
(TO-NRs), acid treated (ATO-NRs), metal oxide loaded (MTO-NRs), and
both acid treated and metal oxide loaded (MATO-NRs) nanorods were
compared based on the rate kinetics and dye degradation efficiencies.
Cobalt oxide (1 wt %) loaded and 1.0 M acid treated TiO2 nanorods (Co/ATO-NR) exhibited the higher photocatalytic degradation
efficiency for Orange-II dye degradation and inactivation of S. typhimurium pathogen compared to other photocatalysts
under solar irradiation. Photoelectrochemical analysis demonstrated
that the charge transfer process in Co/ATO-NR is significantly higher
than that in the untreated samples. The improved photocatalytic activity
of inactive TO-NRs might be due to enhanced charge transfer of finely
dispersed metal oxides on the OH-rich surface of acid treated TiO2 nanorods.
