Research progress in microwave-driven dehydrogenation of LOHCs： design and microwave-absorption performance of responsive catalysts
Le résumé fourni par la source
Liquid organic hydrogen carriers （LOHCs） hydrogen storage technology represents a highly promising hydrogen storage method. The dehydrogenation process of LOHCs is limited by chemical equilibrium and mass and heat transfer，thereby new technologies are required to promote further development. Microwave heating technology exhibits both thermal and non-thermal effects，offering a potential solution to the challenges encountered in dehydrogenation reactions. This technology demonstrates selective activation characteristics in catalytic systems，necessitating the development of highly efficient microwave-responsive catalysts to optimize energy utilization and enhance catalytic efficiency. This article first examines the unique advantages of microwave heating technology and optimization strategies for microwave energy absorption，systematically reviews the research progress of several new microwave responsive catalysts，and examines the advantages and challenges of various materials. The current progress and persistent challenges in applying microwave-responsive catalysts to LOHCs dehydrogenation are subsequently discussed. Secondly，the quantitative methods for the microwave absorption performance of catalysts are summarized，providing guidance for the design and optimization of catalyst structures in terms of absorption and energy distribution. Finally，the design direction of new efficient microwave responsive catalysts and the development direction of microwave responsive LOHCs dehydrogenation technology are discussed，providing theoretical basis for achieving low-temperature and efficient LOHCs dehydrogenation and promoting the development of liquid hydrogen storage technology.
