Abstract	The important challenge in photocatalysis is to find efficient and stable photocatalysts under visible light. Small Bi zero-valent clusters were synthesized on TiO2-P25 by radiolysis. Photocatalytic tests were conducted under UV, visible and solar light with rhodamine B and phenol as model pollutants. Surface modification of TiO2 with zero-valent Bi nanoclusters induces high photocatalytic activity under visible light. Very small amounts of Bi (0.5 wt%) can activate titania for photocatalytic applications under visible light. Time resolved microwave conductivity measurements indicate that under visible irradiation Bi nanoclusters inject electrons into the conduction band of TiO2. These photocatalysts are very stable with cycling.
