Photocatalytic Nanodiodes for Visible‐Light Photocatalysis

Abstract

Oxidative decomposition of toxic pollutants (such as acetaldehyde and isopropyl alcohol), decomposition of water, and photocurrent generation can all be achieved with visible light. Nano-islands of p-type CaFe2O4 interfacing with bulk n-type PbBi2Nb1.9W0.1O9 (shown) form photocatalytic nanodiodes that demonstrate high stability and high activity for such applications.
