While PR of simple organic molecules, 9 sugars, 10,11 biomass 12,13 and even plastic 14–16 has been reported, there has been limited research on food or mixed waste. The few publications on PR of food waste all utilised a TiO 2 photocatalyst coupled with noble metal co-catalysts such as Pt. 16,17 The efficiency and real-world applicability of these systems were therefore limited by their
