Our main model material is composed of titania nanofibers decorated with nanoparticles of silver doped with Congo-red (CR@Ag/TiO 2-nf), which has been selected because of the demonstrated advantages of CR@Ag as a methanol conversion catalyst. Spherical, regular nanoparticles as small as 20 nm were obtained. We show the potential to control the nanofiber surface coverage from 0 to 100%, rationalizing the results on the basis of a detailed mechanism. This approach has been found to be general, and repeatable successfully also with ZrO 2 , Al 2 O 3 , and Li 4 Ti 5 O 12 nanofibers.
