In addition, the storage of coal/water slurries is commercially feasible; therefore, the electrolysis of coal/water slurries helps solve the problem of hydrogen storage. The electrolysis of coal takes place according to the following reactions: 1. C + 2H 2 O -> CO 2 + 4H + + 4e-(1) 4H + + 4e--> … Weband Fe3+ in coal has also been found to have a significant effect on the electro-oxidation process, hydrogen evolution reaction, and coal degradation reaction.30−32 The high …
