The ML-HTS Pipeline Explained
The review outlines an end-to-end pipeline that begins with database construction and descriptor design. Descriptors are categorized into geometric, electronic, energetic, and integrated types, each correlated with material performance metrics such as activity, selectivity, and stability.
High-throughput screening is combined with machine learning models to evaluate large chemical spaces efficiently. This approach reduces the reliance on exhaustive experimental testing by prioritizing promising candidates through data-driven predictions. The pipeline integrates both catalyst and electrolyte screening, addressing the complex interactions at electrochemical surfaces and interfaces.
Applications to Specific Material Classes
Case studies in the review cover single-atom and dual-atom catalysts, high-entropy alloys, and various electrolytes and additives. These examples demonstrate how machine learning models trained on descriptor data can predict performance across diverse material systems.
For instance, the framework supports screening for hydrogen evolution, oxygen reduction, and other key reactions central to clean energy conversion. By incorporating data realism and descriptor universality, the method improves the reliability of predictions for real-world electrochemical conditions.
