A fast, green and one-step method for producing porous carbon spheres, which are a vital component for carbon capture technology and for new ways of storing renewable energy, has been developed by Swansea University researchers.<\/p>\n


\n <\/section>\n

The method produces spheres that have good capacity for carbon capture, and it works effectively at a large scale.<\/p>\n

Carbon spheres range in size from nanometers to micrometers. Over the past decade they have begun to play an important role in areas such as energy storage and conversion, catalysis, gas adsorption and storage, drug and enzyme delivery, and water treatment.<\/p>\n

They are also at the heart of carbon capture technology, which locks up carbon rather than emitting it into the atmosphere, thereby helping to tackle climate change.<\/p>\n

The problem is that existing methods of making carbon spheres have drawbacks. They can be expensive or impractical, or they produce spheres that perform poorly in capturing carbon. Some use biomass, making them more environmentally friendly, but they require a chemical to activate them.<\/p>\n

This is where the work of the Swansea team, based in the University’s Energy Safety Research Institute, represents a major advance. It points the way towards a better, cleaner and greener way of producing carbon spheres.<\/p>\n

The team adapted an existing method known as CVD\u2014chemical vapour deposition. This involves using heat to app<\/a>ly a coating to a material. Using pyromellitic acid as both carbon and oxygen source, they applied the CVD method at different temperatures, from 600-900 \u00b0C. They then studied how efficiently the spheres were capturing CO2<\/sub> at different pressures and temperatures<\/p>\n

They found that:<\/p>\n
