Abstract:
To address the global sustainability challenges and ensure a better quality of life, it is essential to develop cutting-edge energy generation solutions such as water-splitting devices, fuel cells and rechargeable batteries. The success of these technologies is highly dependent upon materials that are both environmentally friendly and economically viable, but finding them is limited by the property trade-offs and multidimensional complexities. Particularly, the field of catalysis experiences hurdles from the random nature of screening numerous materials under operating conditions, a process that heavily depends on traditional trial-and-error strategies and restricts practical applications. Artificial intelligence, employing data mining and machine learning (ML) tools revolutionizes material discovery by accelerating the screening process through efficient exploration of vast chemical space1. MXenes, a class of two-dimensional (2D) materials derived from the selective etching of layered carbides, have emerged as promising candidates for development of innovative energy materials. This presentation highlights the pivotal role of ML in extracting knowledge from MXenes by using implicit data patterns and complex correlations, providing intelligent guidance for the development of advanced catalysts. I will talk about the methods to enhance catalyst performance and explore their impact on the future of sustainable energy technologies. Following this, I will present our recent research on a multistep procedure using supervised ML algorithms to build data-driven models that predict HER and CO2 activation across thousands of MXene configurations2. I will also discuss how computational and experimental integration can accelerate the discovery of efficient catalysts. To conclude, I will present future directions where ML can accelerate autonomous experimentation, quantum-based catalytic innovations and facilitate the development of multifunctional catalysts for future energy solutions.
