近来有一些学者从理论或实践上探讨了模拟植物光合作用的光电化学膜体系用于太阳能转换的可能性。这种体系的核心是一个具有光活性的膜,把两个含有氧化还原偶的水溶液分隔开;当膜受光照时在膜里产生电荷(电子和空穴)的分离,电子到膜的一侧引起一个还原反应而空穴到膜的另一侧引起一个氧化反应。本文用一种聚碳酸酯的透明薄膜(商品名Nuclepore membrane),膜上已用中子照射的方法打好了大小和分布都很均匀的大量微孔,然后在这些微孔里形成CdS沉淀。这样得到的光活性膜体系,改性后在光照时能
Recently, some scholars have discussed theoretically or practically the possibility of using the photoelectrochemical film system for simulating plant photosynthesis for solar energy conversion. At the core of this system is a photoactive membrane that separates two aqueous solutions containing redox couple; the separation of the charges (electrons and holes) in the membrane as the membrane is illuminated and the electron to the membrane The side causes a reduction reaction and holes to the other side of the membrane cause an oxidation reaction. In this paper, a polycarbonate transparent film (brand name Nuclepore membrane), the film has been neutron irradiation method laid a large size and distribution of a large number of uniform pores, and then formed in these pores CdS precipitation. The photoactive film system thus obtained can be modified under illumination
