Abstract Pure hydrogen produced from electrolysis of biomass catalyzed by polyoxometalates (POMs) is promising. KIO3 is cheaper than POMs and has been utilized as a catalyst in the electrolysis of glucose to produce pure hydrogen. It is shown that the appropriate pretreatment temperature and pretreatment time are 80 ℃ and 4 h respectively. Using POMs as a catalyst, the solution was adjusted to pH 0.3 before pretreatment, and pH 3 after pretreatment. However, using KIO3 as a catalyst, it is no need to adjust the pH of the solution. As a result, the process with KIO3 as a catalyst is simpler than that with POMs. Under suitable pretreatment temperature and time, the electrolysis of glucose is stable. The amount of hydrogen is proportional to the time, and the applied potential keeps almost constant during the hydrogen production process.
