In this study, a TiO2/Ti3C2 photocatalyst was successfully designed for the oxidation of xylose to d-xylonic acid under ambient conditions, achieving a yield of 64.2% with excellent stability. Mechanistic study revealed that electron transfer from TiO2 to Ti3C2 significantly increased the life time of light-induced charge carriers, leading to improved photocatalytic performance.
Synthesis of d-xylonic acid, a high value chemical feedstock, from biomass chemicals through a photocatalytic process is of great significance in respect of economical and sustainable concerns, and therefore has aroused considerable attention. Herein, a TiO2/Ti3C2(TT) photocatalyst was designed for the oxidation of xylose to d-xylonic acid under ambient conditions. The photocatalyst is fabricated by in situ growth of TiO2 nano-particles on Ti3C2 nanosheets and exhibits 64.2% of d-xylonic acid yield with excellent stability. The mechanistic study indicates that the electron transfer from TiO2 to Ti3C2 significantly increases the life time of light-induced charge carriers, and hence improved photocatalytic performance.
