In brief
The work asks how a room-temperature liquid-metal electrocatalytic system can reduce CO₂ into solid carbon, and how reactor hydrodynamics and gas–liquid mass transfer affect that electrochemical process.
01 · Scope
The research system
The research spans the coupled parts of an electrochemical reactor: the liquid-metal catalytic interface, delivery of CO₂ into the cell, the behaviour of bubbles through the working fluid, and the solid products recovered after reduction.
Reactor design
Controlled gas delivery
Reactor hardware and bubbling configurations designed to manage how CO₂ reaches the reactive interface.
Hydrodynamics
Bubble behaviour
Gas–liquid mass transfer, multiphase flow and bubble analysis, including Python-based computer vision.
Materials
Carbon characterisation
Raman spectroscopy, XPS, SEM–EDS and XRD used to examine carbon and catalyst materials.
