Special Issue Information

Dear Colleagues,

The chemical storage and release of hydrogen is an important stage in the development of clean energy. Typically, the reactions involved in such technologies require a catalyst to control the hydrogenation and dehydrogenation processes in a stable and efficient manner.

In recent years, the development of hydrogen storage materials and their applications in renewable energy systems have developed rapidly. Reversible chemical hydrogen storage and release based on various carbon-based hydrogen carriers (including carbon dioxide, bicarbonate, nitrogen heterocyclic and aromatic compounds, etc.) has received extensive attention. The practical application of the reversibility of catalytic hydrogenation–dehydrogenation and its reaction conditions in the reaction system provide a reference for the rational design and efficient utilization of the catalyst, and finally enable the industrial application of this technology in the field of chemical hydrogen storage.

In the future, research on the electrochemical hydrogen storage system of multiphase catalysts will focus on the development of new chemical hydrogen storage media with a high hydrogen content, low cost, non-flammability, low toxicity, long-term stability, easy operation and transport, and compatibility with existing energy infrastructure. It will also focus on the rational design of catalysts (e.g., the development of multi-metal composite catalysts, the use of non-precious metals, etc.), and ameliorate the harsh reaction conditions in the dehydrogenation step in order to realize the long-term stable operation of the reaction system.

This paper provides a systematic review of the latest advancements in metal-organic frameworks (MOFs) and covalent organic frameworks (COFs) for electrocatalytic carbon dioxide reduction. Both materials exhibit high specific surface areas, tunable pore structures, and abundant active sites. MOFs enhance CO2 conversion efficiency through improved conductivity, optimized stability, and selective regulation—including bimetallic synergy, pulse potential strategies, and tandem catalysis. COFs achieve efficient catalysis through precise design of single or multi-metal active sites, optimization of framework conjugation, and photo/electro-synergistic systems. Both types of materials demonstrate excellent selectivity toward high-value-added products (CO, formic acid, C2+ hydrocarbons), but they still face challenges such as insufficient stability, short operational lifespan, high scaling-up costs, and poor electrolyte compatibility. Future research should integrate in situ characterization with machine learning to deepen mechanistic understanding and advance practical applications. Full article
