Hydrogen production from Fraxinus mandshurica solid wood waste using FeCl3 as a non-precious metal Lewis acid catalyst: A comprehensive utilization approach

The efficient use of wood powder has become increasingly important for protecting the environment and addressing energy shortages. In this study, a proton exchange membrane electrolysis system was utilized to convert biomass into valuable industrial chemicals and hydrogen using ferric ions as redox mediators, reduced reaction costs. GC-MC analysis revealed that the degradation products are mainly consisted of aromatic carbonyl compounds, along with some alcohols, phenols, and alkanes. The degradation efficiency was found to be 55.6 %, and the Faraday's hydrogen production efficiency exceeds 92.6 %. Moreover, Fe3+/Fe2+ redox mediators was recycled in the electrolysis system, maintaining high reactivity. This research introduces a new approach for the degradation of wood powder, offering potential for sustainable industrial production and a reduction in environmental impact.
