中文摘要:
      3He是理想的核聚变燃料,但是地球上3He的储量十分有限,大约只有500 kg.我们报道了在可见光光照条件下,溴染料敏化担载Pt石墨烯催化水还原为氢气过程中伴生少量氘和氦的实验现象.结果表明在温和条件下自水中的质子生产氘和氦的是可能的.
英文摘要:
      3He is a perfect fuel for nuclear fusion, however, the amount of 3He on the earth is very limited, only around 500 kg. Here, we report that small amount of deuterium and helium can be produced during photocatalytic hydrogen evolution from water catalyzed by Pt-graphene sensitized with Br-dye under visible light irradiation. This work raises a mild route to generate deuterium (D2) and helium (He) from proton in the water under very mild conditions.
