Abstract

This article studies the influence of titania morphology on the biomethane production from cellulose through photoreforming. First, TiO₂ P25 was modified to titania nanotube (TiNT) via short-time hydrothermal reaction. It was confirmed by SEM and TEM that the nanotube morphology of titania could be obtained after heating at 150°C for 7 h. The XRD patterns of the produced powders showed the existence of anatase crystalline phases, with no appearance of rutile. Our mesoporous TiNT had the surface area twice larger than commercial TiO₂ P25 and its bandgap energy was 3.23 eV, which was smaller than TiO₂ P25. Its electron lifetime was longer than TiO₂ P25 (6.82 × 10^–8 s). Due to the better character of TiNT, its cellulose photoreforming to biomethane through TiNT was three times higher than that of TiO₂ P25. The photoreforming by TiNT was 17020 μmol g⁻¹ catalyst, while by TiO₂ P25 was 6560 μmol g⁻¹ catalyst. In this work we also proposed the mechanism of cellulose photoconversion. Overall, TiNT can be a potential photocatalyst in biomass photoreforming reaction.
