Efficient storage of hydrogen fuel in formic acid using an active iron-based catalytic system

摘要

Hydrogen is one of the most important reactants in the chemical industry. It plays key role in the future renewable energy1. It is one of the environmentfriendly fuels used in modern days. If hydrogen is combusted in the engine or fuel cell, only water emerges as exhaust. However, generation of hydrogen and its storage in a safe and reversible manner remain challenging to researchers. Hydrogen is used as clean transportation fuel on a large scale. However, flammability of hydrogen can cause a safety hazard.
