In the context of global warming, the carbon dioxide content in the atmosphere has risen sharply, leading to a series of unpredictable global climate problems. Reducing the amount of carbon dioxide in the atmosphere is nowadays a relatively high concern for researchers.

Scientists are not only looking for energy sources that can replace existing carbon dioxide emissions, but also looking for more new ways to consume carbon dioxide. Among them, there is a highly feasible solution that uses carbon dioxide as a cheap raw material to synthesize valuable materials. Recently, researchers at the Karlsruhe Institute of Technology (KIT) in Germany have invented a new technology that can use carbon dioxide as a raw material to prepare three-dimensional graphene.

The discovery of this new technology has positive significance for reducing carbon dioxide emissions in the atmosphere and slowing down ecological degradation. Similar to this new technology, there are ready-made examples in nature. After photosynthesis, plants produce biomass under the combined action of light, water and carbon dioxide, which closes the cycle of natural substances here. During the conversion process, an important enzyme Rubisco (ribulose-1,5-bisphosphate carboxylase) appears, which can convert free carbon dioxide in the atmosphere into energy storage molecules in organisms, such as sucrose molecules.

Inspired by this enzyme, scientists have developed a new technology. At a temperature of 1000°C, carbon dioxide and hydrogen can be converted into three-dimensional graphene on a metal surface with special catalytic activity. Carbon dioxide preparation of three-dimensional graphene The use of low-cost production raw materials to prepare three-dimensional graphene not only reduces the carbon dioxide content in the atmosphere, but also prepares three-dimensional graphene with excellent performance, which can be described as killing two birds with one stone.
