 · Experimental and theoretical results show that the bismuth–oxygen structure of bismuth oxides is beneficial for a higher adsorption of CO 2 and the rate-determining route switching from the initial fast pre-equilibrium of electron transfer process to the subsequent hydrogenation step, accompanied by a lower free energy of intermediate.

The results indicate that deposited titania nanoparticles on bismuth oxide surface have micro-nano structure, and this composite material exhibits porosity and increased surface hydroxyl groups. Furthermore, the as-prepared photocatalyst shows higher photocatalytic activity to the degradation of 4-chlorophenol than pure titania or P25 under sunlight.

 · Bismuth oxide on titania catalyst was prepared and characterized, and its photocatalytic activitiy was tested. Also investigated was the possibility of a sulfur-sensitive photocatalytic property of bismuth oxide on titania catalyst.
