SnO₂ nanorods were heteroepitaxially grown from rutile TiO₂ (SnO₂-NR#TiO₂) by a hydrothermal method. This paper reports heat temperature (T_c)-dependence of the photocatalytic activity of SnO₂-NR#TiO₂ for the oxidation of ethanol to acetaldehyde. The activity-T_c curve exhibits a volcano-shaped curve with the maximum at T_c = 500 °C. While fusion of a bundle of thin SnO₂ NRs progresses at T_c ≤ 500 °C, heating at T_c ≥ 600 °C causes their segmentation. The high activity of SnO₂-NR#TiO₂ with T_c = 500 °C stems from the high electron mobility in the SnO₂ NRs in addition to the efficient electron transfer through the high-quality junction.
