Pt/P25–x% R catalyst with tuned
anatase–rutile structure obtained by
thermal treatment of P25, 0.1 wt% Pt

300-W Xe lamp with a shutter
window lled with water to remove
infrared light illumination
Maximum hydrogen production was achieved for
Pt/P25–74% R and compared with P25 was
enhanced up to three to ve times. It is proposed
that the anatase–rutile phase structure not only
can enhance the charge separation and
consequently the activity but also adjust the
surface acid/base property, which suppresses the
CO formation from several thousand parts per
million to 5 ppm.
