Influence of iron (II) oxide nanoparticle on biohydrogen production in thermophilic mixed fermentation
The effect of initial pH, metal oxide and concentration of nanoparticles (NP) on hydrogen production were investigated in batch assays using glucose-fed anaerobic mixed bacteria in thermophilic condition of 60 �C. Two type of metal oxide nanoparticles, iron (II) oxide and nickel oxide, were teste...

description |
The effect of initial pH, metal oxide and concentration of nanoparticles (NP) on hydrogen
production were investigated in batch assays using glucose-fed anaerobic mixed bacteria
in thermophilic condition of 60 �C. Two type of metal oxide nanoparticles, iron (II) oxide
and nickel oxide, were tested and both metal capable of increasing the hydrogen yield
about 34.38% and 5.47% higher than the control test. The experiments on the effect of
initial pH were done without adding the nanoparticles to determine the optimum pH for
maximum hydrogen production, in which at pH 5.5, the maximum hydrogen yield has
reached about 1.78 mol H2/mol glucose. However, at pH 5.5 and the optimal iron (II) oxide
concentration of 50 mg/L, the maximum hydrogen yield has reached to 1.92 mol H2/mol
glucose, and the hydrogen content was 51%. Furthermore, the analysis of metabolites has
indicated that the hydrogen production follows the acetic acid pathway. In all experiments
with metal oxide nanoparticles, the metal NP was not consumed by the microbes, and the
amount of it at the end of the fermentation was similar to the starting amount, which can
be concluded that it was acting as an enhancer to the system to improve the hydrogen
production. These results suggest that the addition of iron (II) oxide nanoparticles in the
system is the vital factor to enhance the hydrogen production. |
