论文摘要
固有微孔度PIM 1的聚合物用于分散和沉积PT钛纳米片光催化剂膜。所得的微孔膜允许电解质和氧渗透，从而在玻璃状碳或黑暗中的铂盘电极上产生常规的氧气减少伏安响应。提供了初步数据，表明在电极下减少蓝色LED氧气的脉冲光有效地关闭。暂时将一种机理分配为电极附近氧的光催化耗竭。在NaOH，NaH，Na2HPO4水中观察到光电化学电流反应，并显示出光强度和氧浓度取决于。提出了电分析应用。
The polymer of intrinsic microporosity PIM 1 is employed to disperse and deposit a Pt at titanate nanosheet photocatalyst film. The resulting microporous films allow electrolyte and oxygen permeation to give conventional oxygen reduction voltammetric responses on glassy carbon or on platinum disk electrodes in the dark. Preliminary data are presented showing that with pulsed light from a blue LED oxygen reduction at the electrode is effectively switched off. A mechanism is tentatively assigned as photocatalytic depletion of oxygen near the electrode. Photoelectrochemical current responses are observed in aqueous NaOH, NaCl, Na2HPO4 and shown to be light intensity and oxygen concentration dependent. Electroanalytical applications are suggested.
