Cu-modified TiO2 photocatalysts for decomposition of acetic acid with simultaneous formation of C1-C3 hydrocarbons and hydrogen

- Impregnation, photodeposition or mechanical alloying were used to obtain Cu/TiO2.
- Gaseous products of CH3COOH photodecomposition were CH4, CO2, C2H6, C3H8 and H2.
- The amount of Cu and phase composition affected Cu/TiO2 photoactivity.
- Cu/TiO2 obtained by mechanical alloying was the most active.
