Researchers at the University of Queensland have created a breakthrough nanogenerator capable of absorbing carbon dioxide (CO₂) to produce electricity.
Dr. Zhuyuan Wang and his team developed this innovative device, which combines a polyamine gel used to absorb CO₂ with a boron nitrate skeleton that generates positive and negative ions. When placed in a hydrogel and exposed to CO₂, the device generates electrical signals, demonstrating its ability to convert CO₂ into electricity. This technology not only produces electricity but also actively consumes CO₂, making it carbon negative.
The researchers aim to further improve efficiency and reduce costs, with potential applications including portable devices like mobile phones and larger-scale integration with industrial CO₂ capture processes.
