英文摘要	photocatalysis of methanol (ch3oh) on anatase (a)-tio2(101) has been investigated using temperature programmed desorption (tpd) method with 266 nm light at low surface temperatures. experimental results show that ch3oh adsorbs on the a-tio2(101) surface predominantly in molecular form, with only a small amount of ch3oh in dissociated form. photocatalytic products, formaldehyde (ch2o) and methyl formate (hcooch3), have been detected under 266 nm light irradiation. in addition to h2o formation, h-2 product is also observed by tpd spectroscopy. experimental results indicate that h-2 product is formed via thermal recombination of h-atoms on the bbo sites from photocatalysis of ch3oh on the a-tio2(101) surface, and h-2 production on the a-tio2(101) surface is significantly more efficient than that on the rutile (r)-tio2(110) surface.
