Abstract

   Modern three-way catalysts in catalytic converters, used to control air pollution from automobiles, are still expensive and ineffective at light-off temperatures. Bimetallic nanoparticles were deemed to be the solution to this challenge. However, their superiority remains a myth due to the lack of uniformity in their synthetical methods performed by previous works. Therefore, to elucidate this ambiguity, an informative library of bimetallic three-way catalysts was constructed using a series of high-throughput experiments, which generate a massive quantity of data faster and more consistent than traditional experiments. The information from the library proved that bimetallic catalysts, with their intrinsic alloy synergism, are generally better than their mono-metallic counterparts and thereby suggested some ideas to engineer more powerful and economic alternatives substituting for the current conventional catalysts.
