Advanced heterolytic H2 adsorption of K-added Ru/MgO catalysts for accelerating hydrogen storage into aromatic benzyltoluenes
文献摘要：
Herein,we report a highly active K-added Ru/MgO catalyst for hydrogen storage into aromatic benzyl-toluenes at low temperatures to advance liquid organic hydrogen carrier technology.The hydrogenation activity of Ru/K/MgO catalysts exhibits a volcano-shaped dependence on the K content at the maximum with 0.02 wt％.This is in good agreement with the strength and capacity of H2 adsorption derived from basicity,despite a gradual decrease in the textural property and the corresponding increase in the Ru par-ticle size with increasing the K content.Density functional theory calculations show that heterolytic hydrogen adsorption properties(strength and polarization)are facilitated up to a specific density of K on the Ru-MgO interface and excessive K suppresses heterolytic H2 adsorption by direct interaction between K and hydrogen,assuring the hydrogenation activity and H2 adsorption capability of Ru/K/MgO catalysts.Hence,the Ru/K/MgO catalyst,when K is added in an optimal amount,is highly effective to accelerate hydrogen storage kinetics at low temperatures owing to the enhanced heterolytic H2 adsorption.
