Ethylene glycol as an efficient and reversible liquid-organic hydrogen carrier
NATURE CATALYSIS(2019)
摘要
Hydrogen has long been regarded as an ideal alternative clean energy vector to overcome the drawbacks of fossil technology. However, the direct utilization of hydrogen is a challenge because of the low volumetric energy density of hydrogen gas and potential safety issues. Here we report an efficient and reversible liquid to liquid-organic hydrogen carrier system based on inexpensive, readily available and renewable ethylene glycol. This hydrogen storage system enables the efficient and reversible loading and discharge of hydrogen using a ruthenium pincer complex, with a theoretical hydrogen storage capacity of 6.5 wt%.
