A genuine way to mimic the solar-light conditions in UV driven heterogeneous photocatalytic reactions

摘要

Reliable data on heterogeneous photocatalytic processes with colloidal titanium oxide obtained under well defined laboratory conditions and with direct implication to outdoor conditions are rather rare. Here we report a useful guide on how to balance between (and how to correlate) solely exterior experiments and precisely obtained laboratory data. If produced separately, and comparisons attempted, misleading conclusions might be drawn. For the sake of simplicity all tests are carried out with commercial titania catalyst samples, and with Acid Orange 7, as the quite common model reactant in such reactions.
