使用催化剂和太阳能从水中生产氢气是一种理想的未来能源，不依赖于化石储备。为了经济地使用水和太阳能，需要足够有效、稳定、廉价并且能够收集光的催化剂。在这里，我们表明，一种丰富的材料，聚合氮化碳，可以产生氢从水在可见光照射下的牺牲供体的存在下。与其他导电聚合物半导体相反，氮化碳具有化学和热稳定性，并且不依赖于复杂的器件制造。这些结果代表了光合作用的重要的第一步，在光合作用中，人工共轭聚合物半导体可以用作能量转换器。
The production of hydrogen from water using a catalyst and solar energy is an ideal future energy source, independent of fossil reserves. For an economical use of water and solar energy, catalysts that are sufficiently efficient, stable, inexpensive and capable of harvesting light are required. Here, we show that an abundant material, polymeric carbon nitride, can produce hydrogen from water under visible-light irradiation in the presence of a sacrificial donor. Contrary to other conducting polymer semiconductors, carbon nitride is chemically and thermally stable and does not rely on complicated device manufacturing. The results represent an important first step towards photosynthesis in general where artificial conjugated polymer semiconductors can be used as energy transducers.
