Formic acid (FA) is a promising hydrogen carrier. This review covers recent advances in homogeneous catalysts, particularly C,N/N,N-ligand and pincer ligand types, for efficient FA dehydrogenation to produce clean hydrogen fuel.
Area of Science:
- Catalysis
- Green Chemistry
- Materials Science
Background:
- Formic acid (FA) is a key hydrogen energy carrier.
- Catalytic dehydrogenation of FA produces CO2 and H2 for fuel cells.
- Transition-metal homogeneous catalysts show high activity and selectivity for FA dehydrogenation.
Purpose of the Study:
- To review recent developments in homogeneous catalysts for FA dehydrogenation.
- To focus on C,N/N,N-ligand and pincer ligand-based catalysts.
- To evaluate catalyst performance using the CON/COF metric.
Main Methods:
- Literature review of homogeneous catalysts for FA dehydrogenation.
- Analysis of catalyst structures and their impact on activity and selectivity.
- Evaluation of catalyst cost-effectiveness using the CON/COF assessment.
Main Results:
- Recent advances in C,N/N,N-ligand and pincer ligand homogeneous catalysts for FA dehydrogenation are discussed.
- These catalysts demonstrate high activity and selectivity for H2 production.
- The CON/COF assessment provides a framework for evaluating catalyst economic viability.
Conclusions:
- Homogeneous catalysts, especially those with C,N/N,N and pincer ligands, are effective for FA dehydrogenation.
- Further research is needed to address challenges in catalyst stability and scalability.
- Opportunities exist for developing more cost-effective and sustainable hydrogen production methods from FA.

Esters to Carboxylic Acids: Acid-Catalyzed Hydrolysis
During hydrolysis, the ester is first activated towards nucleophilic attack through the protonation of the carboxyl oxygen atom by the acid catalyst. The protonation makes the ester carbonyl carbon more electrophilic. In the next step, water acts as a nucleophile and adds to the...
Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...

Acid Halides to Carboxylic Acids: Hydrolysis
As shown below, the mechanism involves a nucleophilic attack by water at the carbonyl carbon to form a tetrahedral intermediate. This is followed by the reformation of the carbon–oxygen π bond along with the departure of a halide ion. A final proton transfer step yields carboxylic...
