Photocatalytic material for splitting oxides of carbon

摘要

An embodiment relates to a photocatalytic composite material comprising (a) a first component that generates a photoexcited electron and has at least a certain minimum bandgap to absorb visible light and a structure that substantially prevents the recombination of the photoexcited electron and a hole; (b) a second component that adsorbs/absorbs an oxide of carbon; and (c) a third component that splits the oxide of carbon into carbon and oxygen using the photoexcited electron.

主权项

1. A method of carbon sequestration, the method comprising:
exposing an oxide of carbon to a carbon sequestration device and splitting the oxide of carbon to form carbon black and oxygen;
wherein:the carbon sequestration device comprises a photocatalytic composite material; and the photocatalytic composite material generates a photoexcited electron; adsorbs or absorbs the oxide of carbon; and splits the oxide of carbon into the carbon black and oxygen with the photoexcited electron.
