Carbon dioxide catalysis made more accessible

Many industrial processes emit carbon dioxide into the atmosphere. Unfortunately, however, current electrochemical separation methods are expensive and consume large amounts of power. They also require expensive and rare metals as catalysts. A study now describes a new aerogel electrocatalyst formed from an inexpensive metal alloy, which enables highly efficient electrochemical conversion of carbon dioxide. The main product is formic acid, which is a nontoxic basic chemical.
