IISER Tirupati Researchers Develop Efficient Hydrogen Generation from Methanol and Paraformaldehyde

Researchers at IISER Tirupati have developed an innovative synthetic method for producing hydrogen gas by combining methanol and paraformaldehyde under mild conditions. This new approach has demonstrated remarkable effectiveness, particularly in transferring the hydrogenation of alkynes to alkenes. The combination of methanol and paraformaldehyde shows great potential as a hydrogen carrier, which could revolutionize chemical synthesis and sustainable energy solutions.

The urgent need for sustainable and renewable energy sources has become increasingly apparent due to the rapid depletion of fossil fuels. Hydrogen gas generation is particularly vital, given its potential to replace fossil fuels in energy storage, transportation, and various chemical processes. Methanol and paraformaldehyde, which are produced on a large scale, have emerged as viable hydrogen carriers. Their abundance and widespread manufacture offer significant advantages over the direct use of free hydrogen, especially in terms of storage and transportation.

Under the leadership of Prof. Ekambaram Balaraman at IISER Tirupati, the research team employed commercially available nickel catalysts to produce hydrogen from methanol and paraformaldehyde without the need for bases or activators. This efficient catalytic system demonstrated exceptional performance under mild conditions. The hydrogen generated through this process was successfully used in the chemo- and stereo-selective partial transfer hydrogenation of alkynes, leading to the creation of bioactive molecules with enhanced synthetic value. The research received support from ANRF (erstwhile SERB), a statutory body under the Department of Science and Technology (DST).

The findings of this research, which have been accepted for publication in the journal Catalysis Science & Technology, represent a significant advancement in COx-free hydrogen generation. This breakthrough contributes to the progress of a 'Hydrogen economy,' addressing the challenges posed by increasing global energy demands. The ability to harness methanol and paraformaldehyde as hydrogen carriers marks a crucial step forward in the quest for sustainable energy solutions.

The innovative method developed by Prof. Balaraman and his team showcases the potential of methanol and paraformaldehyde in hydrogen storage and transportation. This development is not only a milestone in chemical synthesis but also a promising solution for the future of sustainable energy.

As the world continues to seek alternatives to fossil fuels, advancements like these are essential in paving the way toward a more sustainable and energy-efficient future.
