摘要: 应用电位扫描和电位-时间程序技术, 研究了四氢呋喃在铂电极上和在HClO_4溶液中电催化氧化时的吸附中间物. 结果表明, 在铂表面上存在三种独方形成的吸附中间物. 论证了这些吸附中间物的可能构型及其形成机理。

Abstract: Using potential sweep and potential-time sequence techniques, we have studied the adsorbed intermediates for the electrocatalytic oxidation of tetrahydrofuran on platinum electrode in HClO_4 aqueous solution, in comparison with the analogouselectrochemical behaviours of n-butanol and 1, 4-butanediol. We arrived at the following main conclusions:
(1) Three different intermediates (P_1, P_2 and P_3) form indenendently from tetrahydrofuran on the surface of platinum anode.
(2) The surface hydrogen is neccessary for the formation of all the intermediates, and the free active site is also neccessary for the intermediate P_1.
(3) Probably the ...
