Abstract |
Activate and reduce: Carbon dioxide was reduced with silane using a stable N-heterocyclic carbene organocatalyst to provide methanol under very mild conditions. Dry air can serve as the feedstock, and the organocatalyst is much more efficient than transition-metal catalysts for this reaction. This approach offers a very promising protocol for chemical CO2 activation and fixation. |
今天偶然看到这个的,还好对化学有点了解。觉得有点意思
1.甲醇的燃烧产物是二氧化碳,现在要把二氧化碳转化为甲醇。那么甲醇通常用作溶剂、防霜剂(antifreeze)、燃料或中和剂。所以,很大情况下就是一个轮回,意义不大。
2. 此过程应该是一个耗能的过程,那么所需的能量从那里来,肯定来自于其他能源,所以这个方法是无法解决能源问题的。
3. 难道这样考虑,利用核能等能源将二氧化碳转化为甲醇,然后作为汽车燃料,这样明显不如电动汽车的效率高。
综上,不看好这项研究。
