摘要

由於能源短缺及溫室氣體排放過多之問題，發展人工催化劑用於產氫，於經濟上及環保上，變成是一項重要的工作。針對此主題，多數的研究從擬生系統開始。因自然界透過氫化酵素，把光合作用中產生之電子及質子轉變成氫氣。透過合成擬生鐵硫催化劑，配合光敏劑，在實驗室裡，氫氣可由酸性溶液下被製備出；本文章將探討此類研究之近期進展。

It is an important issue to economically produce molecular hydrogen due to the incoming energy crisis and green-house gas waste from burning fossil fuels. The most efficient way to accomplish this task is to use synthetic catalysts that are cheap and work at fast rates. In nature, hydrogenase is used to convert the excess reducing power to molecular hydrogen in the presence of protons. In this account, artificial systems for production of hydrogen via biomimetic FeS catalysts that are photo-driven are discussed.
