Raw biomass electroreforming coupled to green hydrogen generation
Despite the tremendous progress of coupling organic electrooxidation with hydrogen generation in a hybrid electrolysis, electroreforming of raw biomass coupled to green hydrogen generation has not been reported yet due to the rigid polymeric structures of raw biomass. Herein, we electrooxidize th...

description |
Despite the tremendous progress of coupling organic electrooxidation with hydrogen generation
in a hybrid electrolysis, electroreforming of raw biomass coupled to green hydrogen
generation has not been reported yet due to the rigid polymeric structures of raw biomass.
Herein, we electrooxidize the most abundant natural amino biopolymer chitin to acetate with
over 90% yield in hybrid electrolysis. The overall energy consumption of electrolysis can be
reduced by 15% due to the thermodynamically and kinetically more favorable chitin oxidation
over water oxidation. In obvious contrast to small organics as the anodic reactant, the
abundance of chitin endows the new oxidation reaction excellent scalability. A solar-driven
electroreforming of chitin and chitin-containing shrimp shell waste is coupled to safe green
hydrogen production thanks to the liquid anodic product and suppression of oxygen evolution.
Our work thus demonstrates a scalable and safe process for resource upcycling and
green hydrogen production for a sustainable energy future. |
