abstract
Photochemical deposition of noble metals in different supports is gaining importance because
of its simplicity and advantages. Its main advantage is the ability of spreading very effectively
the metal throughout the support, thus leading to very high dispersions, resulting in higher
molecular control, with a positive effect on both activity and selectivity. This type of catalysts
is important for industrial preparation of fine chemicals. A common synthetic route in these
processes is the selective catalytic hydrogenation of organic substrates containing unsaturated
functional groups, like steroids or α,β-unsaturated aldehydes.
