摘要：

Photocatalytic oxidation of methanol in air over titanium(IV) oxide particles having a large surface area of 120 m(2) g(-1) using a flow-type reactor at room temperature yielded methyl formate with a high level of selectivity (91 mol%) without catalyst deactivation due to deposition of intermediate(s). The conversion of methanol increased with elevation of the reaction temperature up to 523 K maintaining high selectivity. (C) 2009 Elsevier B.V. All rights reserved.
