Metal-free catalysts for hydrogenation

Subjects

Ethylene feedstocks must be ultrapure for plastics production, but metal-based catalysts used for acetylene removal are limited by cost, scarcity and durability. Now, electrochemical studies demonstrate that 2-thiolimidazole exceeds the efficiency of traditional metal-based catalysts with remarkable selectivity and conversion rates.
