含氮有机液体储放氢催化体系研究进展
Research progress in catalytic system for hydrogen storage and release from nitrogen-containing liquid organic carriers
摘要
Abstract
As an important secondary energy,hydrogen is of high energy density,environmental friendliness and wide use,which is an important direction of human strategic energy development.However,hydrogen storage and transportation are still facing problems of high cost and safety.The hydrogen storage and release technology based on liquid organic hydrogen carriers(LOHCs)has become one of the available technologies with its advantages of relatively high hydrogen storage density,mild storage conditions and convenient transportation.Compared with polycyclic aromatic hydrocarbons,nitrogen-containing LOHCs is milder in catalytic hydrogenation and dehydrogenation,which can effectively improve the robustness of hydrogen storage and release and the reaction efficiency.Based on this,this paper systematically reviewed the progress in hydrogenation and dehydrogenation of nitrogen-containing LOHCs,and revealed the reaction pathway and catalytic mechanism of these two kinds of reactions.Then,the hydrogenation/dehydrogenation catalysts were systematically summarized from the aspects of active center,support,bimetallic synergistic effect,reaction conditions,catalyst stability,etc.After that,the reaction kinetics models based on the series reactions and reaction network were analyzed in detail.At last,the current challenges of nitrogen-containing LOHCs were introduced,as well as the perspectives of LOHCs systems.However,there are still many problems for this technology,and further in-depth research should be conducted in the aspects of formulation system of organic hydrogen carriers,continuous hydrogen storage and release reaction system,catalyst design and preparation,structure-activity relationship of catalysts,precise reaction kinetics,and comprehensive physicochemical properties database.关键词
