Why Did the World Pay Attention to the Korean Researchers' '10-Year-Old Paper'?

Single-Atom Catalyst Technology Paper Published as a 'Special Invited Review' in a Recent International Journal
Attention on Catalyst Technologies for Hydrogen Production and Carbon Dioxide Utilization Toward Carbon Neutrality
Potential Use of Efficiency Maximization Techniques to Reduce High Catalyst Costs

[Asia Economy Reporter Kim Bong-su] Korean researchers' technology utilizing atomic-level catalysts, studied 10 years ago, has recently gained global attention. As carbon neutrality to prevent global warming has become an urgent task for humanity, this technology has emerged as essential for hydrogen production and carbon dioxide resource utilization.

According to the Korea Advanced Institute of Science and Technology (KAIST) on the 1st, the international journal in the field of new materials published by the American Chemical Society, Accounts of Materials Research, selected a paper on single atom catalysts developed for the first time in the world in 2010 by Professor Kim Sang-wook and his research team from KAIST's Department of Materials Science and Engineering as a "special invited review paper" and featured it on the cover.

This is analyzed to be because, amid the global attention on catalyst technology, the technology devised by Professor Kim's team 10 years ago can inspire researchers and developers in related fields.

Catalysts refer to materials that enhance the efficiency of various chemical reactions with only a small amount of addition. Their importance has rapidly increased recently in the fields of environment, energy, bio, and health. In particular, research to replace expensive catalysts such as platinum or rare earth elements in energy conversion reactions of hydrogen fuel cells, which are core to renewable energy, and environmentally friendly hydrogen fuel production reactions has become a hot topic in new materials research worldwide.

Professor Kim's team proposed single atom catalysts, which can achieve maximum efficiency with the same amount of catalyst and was the first in the world. They discovered that iron (Fe) atoms form a single-atom hybrid structure similar to the hemoglobin structure in our blood during the chemical growth process of carbon nanotubes, presenting a new fuel cell catalyst based on a single atom. This catalyst attracted attention as a new form of catalyst that can overcome the limitations of conventional platinum catalysts, which have a short lifespan due to particle aggregation.

Since Professor Kim's research, many research groups worldwide have recently entered the field of single atom catalyst research, and it is known to be the most promising field for developing new high-efficiency catalysts.

Professor Kim Sang-wook explained, "The recently published review comprehensively summarizes the latest research trends from the manufacturing of single atom catalysts, which started with doping metal elements into nanomaterials such as graphene, to their structure, properties, and applications," adding, "We hope it will provide profound insights into future research in this field and become the starting point for the commercialization of high-efficiency single atom catalysts."
