Title : H2S: A new comprehension of its role in human activity


The concept of the decisive role of solid catalysts in the reaction of low-temperature decomposition of H2S is considered in the framework of non-equilibrium thermodynamics of an irreversible process in an open system [1]. The reaction proceeds at room temperature without the use of external energy sources due to the internal chemical energy of H2S molecules.  In the gas phase, this reaction is thermodynamically impossible. The reaction products, along with hydrogen, are either solid sulfur (sulfide catalysts) or diatomic gaseous sulfur in the ground triplet state (metal catalysts) [2]. Various types of solid catalysts have been proposed for the process [3]. The developed concept makes it possible to solve not only the problem of the effective practical use of H2S, but also opens new pages in the chemistry of this substance as a source of atomic hydrogen and an energy supplier for the activation of chemically inert molecules (CO2, N2, Ar, etc). Moreover, the gaseous triplet sulfur discovered by us can be used in various fields of chemistry, pharmacology, medicine, etc. Thus, "useless" H2S acquires the status of a "useful" chemical, which will undoubtedly be in demand to solve problems that could not be realized within the framework of the previous paradigm of high-energy utilization of H2S [4].


Startsev Anatolii Nikolaevich is a retired Russian chemist known for his research in catalysis. He graduated from the Tomsk Polytechnic University in 1972 and subsequently joined the G.K. Boreskov Institute of Catalysis in Novosibirsk, where he worked as a researcher for over four decades. His work focused on the properties and synthesis of supported catalysts, resulting in significant contributions to the understanding of these catalysts' behavior. In 1977, he earned his Ph.D. with a thesis on the properties of catalysts prepared via organometallic and alkoxide complexes. Later, in 1997, he became a Professor of Chemistry, delving further into sulfide HDS catalysts' synthesis, structure, and properties. Since his retirement in 2016, Anatolii Nikolaevich has enjoyed his pensioner status, leaving behind a legacy of valuable research in the field of catalysis.
