MIEC Hollow-Fibre Membranes in a Plasma Membrane Reactor

The article delves into the innovative use of perovskite hollow-fibre membranes in a plasma membrane reactor for the efficient separation of oxygen from CO2. By utilizing regenerative energy and a microwave plasma, the process aims to split CO2 into CO and O2, with the latter being selectively separated through the membranes. The membranes, manufactured via a wet-spinning process and sintered at high temperatures, exhibit exceptional stability and permeability, even in harsh CO2 environments. The study also showcases the rapid response time of the membranes to fluctuations in energy input, a critical feature for practical applications. The results demonstrate the potential of this approach for reducing CO2 emissions and storing regenerative energy in a chemically stable form.
