Electrode’s ‘hot edges’ convert carbon dioxide gas into fuels and chemicals

A team of scientists has created a bowl-shaped electrode with ‘hot edges’ which can efficiently convert CO2 from gas into carbon based fuels and chemicals, helping combat the climate change threat posed by atmospheric carbon dioxide.

The research team, from the University of Bath, Fudan University, Shanghai, and the Shanghai Institute of Pollution Control and Ecological Security, hopes the catalyst design will eventually allow the use of renewable electricity to convert CO2 into fuels without creating additional atmospheric carbon – essentially acting like an electrochemical ‘leaf’ to convert carbon dioxide into sugars.

Using this reaction, known as the reduction of carbon dioxide, has exciting potential but two major obstacles are poor conversion efficiency of the reaction and a lack of detailed knowledge about the exact reaction pathway.

This new electrode addresses these challenges with higher conversion efficiency and sensitive detection of molecules created along the reaction’s progress – thanks to its innovative shape and construction. The bowl shaped electrode works six times faster than standard planar – or flat – designs.
