Abstract Chloroaluminate ionic liquids selectively transform (waste) polyolefins into gasoline-range alkanes through tandem cracking-alkylation at temperatures below 100 °C. Further improvement of this process necessitates a deep understanding of th

The open circuit potential (OCP) complicates catalytic reactions significantly. Here the authors demonstrate that the self-established OCP at the catalyst-aqueous interface is important to stabilize the cationic intermediate and transition state, and

Hydrogen binding and furfural adsorption are critical steps in Pd-catalyzed furfural hydrogenation reactions in aqueous phases. Here, the authors explore how hydronium ion at different pH values modifies the rate constant for this reaction.
