Optimizing multi-metallic alloy catalysts, composed of two or more elements, is crucial. However, traditional calculation methods have limitations in finding experimentally feasible catalysts, due to disparities between computational and experimental results. Thus, we have proposed a novel approach that combines experimental data and active learning to effectively explore the ideal composition of multi-metallic alloy catalysts. By utilizing solid-solution nanoparticles synthesize by the carbothermal shock (CTS) method and testing their hydrogen evolution reaction (HER) performance, the model was updated iteratively. This approach successfully identified a metal precursor composition with an HER overpotential of 54.2 mV, surpassing pure Pt catalysts synthesized through the same method. Thus, the model demonstrates successful operation solely based on the precursor mixture's component and composition as input data.
