The development of scientists from the Institute of Nanotechnology, Electronics and Instrument Engineering (INEP) of the SFU Academy of Engineering and Technology can find application in the production of environmentally friendly fuel and energy storage. In addition, the technology will significantly improve the efficiency of water splitting, contributing to the transition to sustainable energy.
A pressing issue in the modern world is the search for new energy technologies that will not cause damage to the climate and will be beneficial for the economy. One of the successful types of such technologies are catalysts – substances or materials that accelerate electrochemical reactions. They are used to improve hydrogen and oxygen electrolysis processes, as well as to improve the performance of fuel cells and batteries.
Today, the most effective such electrocatalysts are platinum and its derivatives. However, these materials are extremely expensive and do not provide protection against fuel oxidizing chemicals or long-term operational reliability. To solve this problem, scientists from Taganrog, under the leadership of leading researcher at the Research Laboratory of Functional Nanomaterials Technology Tatyana Myasoedova, have created a new material – copper-molybdenum sulfide (CuMoS), which will help more efficiently generate hydrogen and oxygen from water.
This work is the implementation of the idea of Rajatsing Kalisulingam, senior researcher at INEP SFU. The results of his research were published in the journal Chemistry Europe.
According to Tatyana Myasoedova, over the past few decades, various transition metal catalysts have been investigated for electrochemical applications, decomposition of pollutants, and especially water splitting. Copper ions are the main ones among these metals due to their good conductivity, high stability, availability and low cost. Research by other scientists has shown that MoS2 with 1T crystalline phase is able to achieve good catalytic performance without any oxidation at the active edges.
- Therefore, the main goal of the research was to purposefully synthesize CuMoS with higher electronic conductivity, stability, and durability,” the scientist emphasizes. “The practical significance of our results lies in the potential for the production of environmentally friendly hydrogen and energy storage. This technology could significantly improve the efficiency of water splitting, contributing to the transition to sustainable energy.
Experts also note that in the future the team faces the task of optimizing the synthesis process of CuMoS microrods, expanding the scale of production and testing the material in real conditions.
