Separation-Free High-Purity Hydrogen Production via the Mechanochemical Ammonia–Silicon Reaction under Mild Conditions
First Author: Seung-Hyeon Kim (UNIST)Corresponding Authors: Runnan Guan, Qunxiang Li, Hankwon Lim, Jong-Beom Baek (UNIST & USTC) Research BackgroundAmmonia (NH₃) is a highly promising hydrogen carrier (containing 17.6 wt% hydrogen), but traditional thermal catalytic cracking requires 400–600 °C, resulting in a mixture of H₂/N₂/NH₃, with subsequent PSA purification accounting for 47.6% of the total equipment … Read more
