Energy-Positive Thiosulfate Production Enabled by Coupling Waste Sulfide Oxidation with Oxygen Reduction
In the authors' words
This journal does not let us republish the full abstract. Here are the two sentences Pipette selected, quoted from it. Read the rest at the publisher.
Main result
Here we develop a galvanic electrochemical-chemical cascade strategy that couples the sulfide oxidation reaction (SOR) with the two-electron oxygen reduction reaction (ORR), enabling sulfide valorization with net positive electrical energy output.
Limitation the authors admit
Preliminary techno-economic analysis further indicates that ORR coupling reverses the electricity term from a cost penalty to an energy credit.
