• particle size is the SSA, which is a good measure for non-porous, untreated, and nearly spherical TiO2 particles, independent of sample dispersion. However, we advise against using average ECD or MinFeret values for such calculations. To obtain reliable and accurate results over a wide range of particle

The hydrolysis and condensation of the TBOT precursor are highly influenced

• , the particle diameter decreased to ≈340 nm and most of the particles were individually isolated without particle agglomeration (Figure 1b). When the volume ratio of EtOH/ACN was 2:2, the particle size of the spherical TiO2 particles became even smaller, reducing to ≈250 nm without apparent particle

Despite the fact that we used the same preparation procedure for the Au deposition and formation of Au NPs on the TiO2 film as on the dispersed TiO2 support, the Au
