  • Hydrogenation without H2 Using a Palladium Membrane Flow Cell

    Electrocatalytic palladium membrane reactors (ePMRs) use electricity to hydrogenate organic molecules at ambient temperature and pressure. These benign reaction conditions position ePMRs as a sustainable alternative to thermochemical hydrogenation, which requires high-temperature and high-pressure reaction conditions. However, ePMRs suffer from slow reaction rates and a limited understanding of the factors that govern reaction performance in these devices. In this work, we report the design and validation of an ePMR flow cell. This flow cell increases reaction rates 15-fold and current efficiencies by 30% relative to H-cell reactors. We use this device to reveal that the hydrogen content in the palladium membrane governs the speed and selectivity of hydrogenation reactions, while the amount of hydrogen gas evolved at the palladium surface is deterministic of current efficiency. We contend that this flow cell, which enables hydrogenation without hydrogen gas, is an important step for translating ePMRs into practice.

    From cold fusion to pharmaceuticals

    Revisiting "cold fusion" led us to discover the electrolytic hydrogenation/deuteration reactor that is electrically-driven and uses water as a hydrogen/deuterium source. This technology opens new avenues for using renewable energy to make valuable chemicals, including pharmaceuticals.

  • I am happy to read another useful application of the research on LENR by the team of Pr. Berlinguette in NATURE CATALYSIS.

    Years ago, we have demonstrated that our palladium cathodes were producing atomic hydrogen. It is probably the reagent of Berlinguette team.

    In this article, we published the deuteriation of benzoquinone into hydroquinone by a palladium cathode. Our goal was not to do chemistry, but to make paper that changes color on contact with atomic hydrogen. (or in contact with atomic deuterium) (I write « palladium » by mistake instead of "deuterium" in my previous post, sorry.)
