Creaflow is pleased to share a new peer-reviewed publication in Electrochimica Acta, co-authored by Koen Van Aken with collaborators from the University of Antwerp. The article reports a reactor concept aimed at boosting mass transfer in synthetic electrosynthesis. Read more via the publisher page.

Reactor concept and scope

The study introduces an electrochemical oscillatory flow reactor that applies a controlled oscillatory flow regime over conductive pillar-array electrodes. These pillars function as both electroactive interface and turbulence promoters, enabling on-demand control of mass transfer with pulse frequency and amplitude while reducing dependence on net flow or residence time.

Performance and implications

Compared with conventional steady-state flow, the authors report up to a fourfold increase in limiting current density, indicating significantly enhanced mass transport and a clear route toward higher productivity in flow electrosynthesis. This bridges bench-scale insight with process-relevant performance for R&D and scale-up.
