摘要	Hydrogen (H-2) production fromphotocatalytic reforming of cellulose is a promisingway for sustainable H-2 to be generated. Herein, we report a systematic study of the photocatalytic reforming of cellulose over Pt/m-TiO2 (i.e. mixed TiO2, 80% of anatase and 20% of rutile) catalysts in water. The optimum operation condition was established by studying the effect of Pt loading, catalyst concentration, cellulose concentration and reaction temperature on the gas production rate of H2 (r(H2)) and CO2 (rCO(2)), suggesting an optimumoperation condition at 40 degrees C with 1.0 g.L-1 of cellulose and 0.75 g.L-1 of 0.16-Pt/m-TiO2 catalyst (with 0.16 wt% Pt loadting) to achieve a relatively sound photocatalytic performance with r(H2) = 9.95 mu mol.h(-1). It is also shown that although the photoreforming of cellulose was operated at a relatively mild condition (i.e. with an UV-A lamp irradiation at 40 degrees C in the aqueous system), a lowloading of Pt at similar to 0.16wt% on m-TiO2 could promote the H-2 production effectively. Additionally, by comparing the reaction order expressed from both r(H2) (a1) and r(CO2) (a(2)) with respect to cellulose and water, the possible mechanism of H2 production was proposed.
