[资源] nature chemistry最新：TiO2负载Au纳米颗粒

Metal nanoparticles that comprise a few hundred to several thousand atoms have many applications in areas such as
photonics, sensing, medicine and catalysis. Colloidal methods have proven particularly suitable for producing small
nanoparticles with controlled morphologies and excellent catalytic properties. Ligands are necessary to stabilize
nanoparticles during synthesis, but once the particles have been deposited on a substrate the presence of the ligands is
detrimental for catalytic activity. Previous methods for ligand removal have typically involved thermal and oxidative
treatments, which can affect the size or morphology of the particles, in turn altering their catalytic activity. Here, we
report a procedure to effectively remove the ligands without affecting particle morphology, which enhances the surface
exposure of the nanoparticles and their catalytic activity over a range of reactions. This may lead to developments of
nanoparticles prepared by colloidal methods for applications in fields such as environmental protection and
energy production.
