Designing less noble yet high-performing multimetallic catalysts for catalytic converters using a high-throughput approach

Key Points

• The research aims to identify less noble yet high-performing multimetallic catalysts for catalytic converters.
• Conducted high-throughput screening of 140 multimetallic catalysts.
• Analyzed formulations with 40–60% precious metal group metals (PGM).
• Utilized machine learning and statistical methods to understand metal synergies.
• Identified cost-effective catalyst formulations with enhanced NO reduction performance.
• Achieved T 50 values ranging from 271 to 296 °C for NO reduction.
