Valorisation of lignocellulose and low concentration CO₂ using a fractionation-photocatalysis-electrolysis process.

ABSTRACT: The simultaneous upcycling of all components in lignocellulosic biomass and the greenhouse gas CO₂ presents an attractive opportunity to synthesise sustainable and valuable chemicals. However, this approach is challenging to realise due to the difficulty of implementing a solution process to convert a robust and complex solid (lignocellulose) together with a barely soluble and stable gas (CO₂). Herein, we present the complete oxidative valorisation of lignocellulose coupled to the reduction of low concentration CO₂ through a three-stage fractionation-photocatalysis-electrolysis process. Lignocellulose from white birch wood was first pre-treated using an acidic solution to generate predominantly cellulosic- and lignin-based fractions. The solid cellulosic-ba
