Abstract
A carbon dioxide reducing photocatalyst is provided. The carbon dioxide reducing photocatalyst comprises: an electron receptor comprising a metal oxide; a polymer concentrator deposited on the electron receptor; and a metal catalyst deposited on the electron receptor, wherein electrons move from the polymer concentrator to the metal catalyst through the conduction band of the electron receptor if the polymer concentrator absorbs light.
Claims10
A carbon dioxide reducing photocatalyst comprising:
- an electron acceptor including a metal oxide;
- a polymer concentrator deposited on the electron acceptor;
- and
- a metal catalyst deposited on the electron acceptor, wherein
- electrons move from the polymer concentrator to the metal catalyst through the conduction band of the electron acceptor when the polymer concentrator absorbs light.
