Ultra‐High‐Efficiency On‐Chip CO 2 Conversion by Nanosecond Self‐Pulsing Micro‐Plasma Devices

ABSTRACT Conversion of CO 2 into carbon‐neutral fuels and chemicals remains a central challenge in sustainable chemistry and energy sectors, as conventional catalytic processes are critically limited by the thermodynamic equilibrium and low overall energy efficiency. Here, a micro‐plasma chip for CO 2 ‐to‐CO conversion is introduced that achieves ultra‐high energy efficiency and breaks the thermodynamic equilibrium limitation under ambient conditions. These micro‐plasma devices (MPDs) with sub‐10‐µm discharge gaps self‐generate nanosecond pulses directly from a DC bias without external pulsed‐power sources and drive discharges through field emission at substantially lower voltages than conventional plasma…
