Bifunctional Pd-Al:SrTiO 3 photocatalyst sheet for m 2 -scale waste PET photoreforming and feasibility study

, formate, glycolate and glycolaldehyde, respectively, were produced. A comprehensive feasibility study was performed based on this prototype waste PET reforming system to identify key areas to prioritise in future research. Although photocatalytic reforming was unsurprisingly found to be premature for practical application, reactor cost and photocatalyst stability were identified as critical issues to realise a feasible large-scale system in the future. This work presents a robust bifunctional photocatalyst system and provides a systematic feasibility assessment of large-scale PET reforming.
