The utilisation of the greenhouse gas CO2 combined with H2O for the production of syngas (CO+H2) provides a sustainable means to produce industrially important chemical feedstock. The pre-treatment conditions at near-neutral pH during enzymatic PET hydrolysis enables the utilisation of the plastic monomers as a feedstock for solar-driven CO2-to-syngas production (Figure ), which is usually performed at near-neutral pH. Therefore, as a final demonstration we employ the LCC-treated PET films with a recently reported TiO2|CotpyP photocatalyst (see Experimental Section for details) for CO2-to-syngas conversion coupled to plastics oxidation. CotpyP is a Co 2+ -based molecular CO2 reduction catalyst coordinated by two terpyridine ligands bearing phosphonate groups for anchoring onto TiO2.
