Hydrogen (H

2

) production from photocatalytic reforming of cellulose is a promising way for sustainable H

2

to be generated. Herein

we report a systematic study of the photocatalytic reforming of cellulose over Pt/m-TiO

2

(

i.e

. mixed TiO

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 H

(

suggesting an optimum operation condition at 40 ℃ with 1.0 g·L

of cellulose and 0.75 g·L

of 0.16-Pt/m-TiO

catalyst (with 0.16 wt% Pt loadting) to achieve a relatively sound photocatalytic performance with

. 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 ℃ in the aqueous system)

a low loading of Pt at ~0.16 wt% on m-TiO

2

could promote the H

2

production effectively. Additionally

by comparing the reaction order expressed from both

) and rCO

(a

) with respect to cellulose and water

the possible mechanism of H

production was proposed.
