The process described in the paper uses both gallium and silver as catalysts. The advantage of using gallium is that it is in liquid form.
When the gallium is regenerated after catalyzing one cycle of the reaction, it mixes again with the liquid gallium. Being liquid ensures a long life for the catalyst. Solid catalysts are never recovered perfectly after taking part in the reaction and then being again deposited on their support, so they degrade much faster. The mechanism of solid catalyst degradation is similar to that which limits the life of a rechargeable battery with solid electrodes. |
