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.

Abstract

High-throughput screening of 140 multimetallic catalysts identifies cost-effective formulations with 40–60% PGM achieving superior NO reduction ( T 50 = 271–296 °C). Machine learning and statistics provide insights into metal synergies and promoters.
