The performance of unfunctionalised TiO 2 P-25 as a photocatalyst, with its large band gap (3.2 eV) and high rate of photogenerated charge recombination, has motivated a significant body of research aimed at optimising its photocatalytic efficiency and visible light absorp-tion. In particular, the use of metal, co-catalyst nanoparticles has been proposed to achieve these goals, and make TiO 2 a viable photocatalyst for applications range from H 2 generation and CO 2 reduction to pollution remediation. Therefore, it is important to verify that our polymer bridge-based approach to nanoparticle attachment is still viable after the surface modification of TiO 2 from its "clean", unfunctionalised commercial form using standard, wet-chemistry methods.
