The best performing TiO2|Pt photocatalyst was used to fabricate the panel (see Experimental Section for details), which was then mounted in the reactor. Since PET production and consumption is larger than that of PCL, a PET film was used for this proofof-concept demonstration using the integrated system along with LCC enzyme (see Experimental Section for details), where the monomers generated from the PET through LCCpre-treatment can be directly utilised during photoreforming using the TiO2|Pt panel.
