TiO_2在不同基质上光催化活性的比较

The comparison of photocatalytic activity of titanium dioxide on different substrates

研究了不同基质对纳米 Ti O2 光催化活性的影响。采用甲基橙作为脱色对象 ,以脱色速率常数作为衡量光催化活性的标准 ,发现金属基质更有效 ,且对 Ti O2 光催化活性有明显的协同作用 。

The substrate effects on photocatalytic activity of nanometer TiO 2 are studied. Methyl orange's decoloration rates are taken as criterion to estimate the photocatalytic activity of nanomater TiO 2. Metal substrates are found more efficient and generally have synergetic effects on TiO 2, and zinc plated iron is the most efficient substrate.
