Hydrogen energy is recognized as a key solution for clean energy due to its high energy density and zero pollution emissions. However, the current reliance on fossil fuels for hydrogen production hinders carbon neutrality efforts. To address this, researchers from Beijing University of Technology and the Chinese Academy of Sciences have developed a groundbreaking approach by fabricating PtCo/MXene catalysts for the hydrogen evolution reaction (HER). This innovative catalyst exhibits superior HER activity with minimal overpotential and exceptional durability in an acidic medium. By introducing cobalt species, the catalyst's electronic structure is optimized, enhancing the catalytic performance of platinum. The PtCo/MXene catalyst's specific surface area and charge transfer impedance further contribute to its efficiency. Additionally, Density Functional Theory (DFT) calculations confirm the catalyst's ability to promote H* desorption and facilitate the HER process. This research highlights the potential of low-load precious metals on MXene to revolutionize HER electrocatalysis, ensuring both high activity and stability in hydrogen production.
