Heterogeneous photocatalysis

Heterogeneous Photocatalysis

higher secondary education

V1 Photocatalytical reduction of methylene blue with TiO₂ while nitrogen is bubbling through the solution and reoxidation using air (reversible reactions on the chromophore)
- Video of the experiment
V2 Photocatalytic oxidation of methylene blue with TiO₂ while oxygen is bubbling through the solution (irreversible destruction of the chromophore)
- Video of the experiment
V3 Complete mineralisation of tetrachloro ethylene with TiO2 using a selfmade solar reactor and detection of the reaction products CO₂(g) und HCl(aq)

V4 Photocatalytical water photolysis in two steps using CuCl and TiO₂

Technical Contents

energy band model for the function principle of a TiO₂ particle as a photocatalyst in a heterogeneous system; photocatalysis as light induced electron transfer; water splitting using light driven photocatalysis

Scope

energetics, catalysis (environmental technology, possible hydrogen production using water photolysis) (higher secondary education); Engineering: Conceptual design and construction of a solar reactor
