| 摘 要： | 主要介绍两类半导体光电化学制氢体系。一类是SiC体系，通过对KOH中的P-SiC和Na2SO3中的n-SiC两电极构形作电流－电压（I－V）研究表明，随着太阳光照射，有值得重视的光电流产生，这相当于水在各自的电极上分裂形成氢和氧。另一类是CdS体系，通过并入ZnS和Mo，在光照下，光电流增加，即获得了氢气释放的更大的电势。

| Abstract: | Two semiconductor photoeletrochemical systems for hydrogen production were introduced.One was SiC,in which photocurr ent generation was appreciable with illumination of the sunlight,corresponding t o water splitting to form hydroge n and oxygen at respective electrodes.The other was CdS system,in which photocur rent increased by mixing CdS with ZnS and Mo under illumination,to get m ore potential for hydrogen production. |

| Keywords: | production of hydrogen semiconductor photocurrent band gap |
