Researchers at MIT have developed a method that could significantly boost the performance of carbon capture and conversion systems that use catalytic surfaces to enhance the rates of carbon-sequestering electrochemical reactions. The movement through water is sluggish, which slows the rate of conversion of the carbon dioxide.
As water-splitting technologies improve, often using porous electrode materials to provide greater surface areas for electrochemical reactions, their efficiency is often limited by the formation of bubbles that can block or clog the reactive surfaces. As a result, there were substantial changes of the transport overpotential.
