| 摘 要： | 直接甲醇燃料电池 (DMFC)可直接利用甲醇 ,无须中间转化装置 ,具有系统结构简单、体积能量密度高、燃料补充方便等优点 .从提高电流密度和稳定催化剂本征活性这两方面来看 ,DMFC需要解决的关键问题是使甲醇直接氧化的阳极材料 .近年来有关此类阳极材料的制备与催化性能的研究报道日益增多 [1,2 ] ,但都是单纯地从光催化或电催化的角度出发 .本文提出一种利用 Ti O2 为光催化剂 ,Pt- Ru为电催化剂 ,试图将光催化与电催化反应发生于一体 ,使甲醇能得到联合的催化氧化作用 ;同时为了能进一步增加Ti O2 的光催化氧化能力 ,改变 Ti O2 - n…

| Abstract: | The photo-electro-catalytic oxidation of methanol in acid solution on Pt-Ru modified and unmodified titanium dioxide film electrodes has been studied. The photo-catalysis current of the OTE/TiO_2 electrode and photo-electro-catalysis current of the OTE/TiO_2/Pt-Ru electrode both were three order of magnitude larger than that created by the common electrical oxidation. In addition, the effect of Pt-Ru on the current is described. The electrode sensitized by RuL_2(NCS)_2 showed a broader photoresponse spectral region. |
