High specific surface area worm-like mesoporous chromium oxides were fabricated using the glucose-assisted thermal decomposition approach with chromium nitrate as the metal source. The physicochemical properties of the materials were characterized by XRD, TEM, TPRand N₂ adsorption-desorption techniques, and the catalytic activity was evaluated for the oxidation of the toluene. The m-Cr-5 catalyst via 500 ℃ calcination process exhibits the highest specific surface area of 162 m²·g^-1, the average pore size of 6.2 nm, and the excellent low temperature reducibility and multiple oxidation-state chromium species coexistence. Compared to the bulk chromium oxide, the factors such as low temperature reducibility, high-surface area, and multiple oxidation-state chromium species coexistence are responsible for the excellent catalytic performance of m-Cr-5 in toluene combustion.
