It was observed that with increasing enzyme-mediated hydrolysis of the PET film, the amount of H2 production was also enhanced (Figure ; Table ). After 96 h, the TPA yield was ~322 µM and the amount of H2 produced 9784 µmol mirr -2 (~5 µmol gcat -1 h -1 ). A change in the texture and transparency of the PET film caused by the enzymatic attack was observed after the experiment, as shown in Figure , which was further confirmed using field emission scanning electron microscopy (FESEM) imaging (Figure ). This further attests that the enzymes are active under the given conditions producing monomers of EG and TPA through PET hydrolysis. The EG formed from PET can be oxidised by the panel in-situ to produce organics, with the simultaneous generation of H2 from the solution. H-NMR spectroscopy of the solution after 96 h of photoreforming confirmed the presence of the oxidation product of EG, formate (5 µmol; Figure ). Control experiments with blank buffer solutions in the absence of plastics showed negligible H2 production after 96 h (Figure ; Table ).
