电化学CO2还原反应(CO2RR)被认为是在温和反应条件下将CO2转化为有用和增值化学品/燃料的有前景的途径。然而,由于CO2活化和C=O键断裂的高能垒,CO2RR的发展受到过电位过高、能量转换效率差和竞争性析氢反应(HER)的阻碍。
Scientists have developed a way to convert carbon dioxide (CO2), a potent greenhouse gas, into carbon nanofibers, materials with a wide range of unique properties and many potential long-term uses.
A team of scientists has developed a novel technique to convert carbon dioxide (CO2) from treated flue gas directly into high-value chemicals and fuels. This innovation sidesteps the conventional ...

实现CO2高选择性光还原CH4

重要的清洁燃料,可用作生产天然气、炭黑和其他高附加值化学品的工业原料。尽管人们为提高CO2光还原生成CH4的效率做了大量的工作,但由于该过程是一个八电子还原反应,复杂的质子-电子转移途径容易导致产生不需要的产物,严重阻碍了CH4的形成。因此,开发高效 ...
