Biocatalytic artificial photosynthesis integrates photocatalysis and redox biocatalysis {through|via|by means of|by way of} inspiration from plants to synthesize value-added {chemicals|chemical substances|chemical compounds} {using|utilizing|making use of|employing|working with|applying} solar {energy|power}.

A Zr-doped hematite photoanode (i) extracts electrons from hydrolyzed PET {solutions|options} obtained from post-consumer PET wastes (e.g., drinking bottles) and (ii) transfers the electrons {to the|towards the|for the} bioelectrocatalytic {site|website|web site|internet site|web-site|web page}.
