Abstract:
It was the first time to study the catalytic effect of mesoporous magnetic Fe 3 O 4 nanoparticles on the biohydrogen production. The mixed culture used in this study just suffered from an alkaline shock and lost its bioactivity of hydrogen production. We use mesoporous Fe 3 O 4 nanoparticles and ferrous ions as activators to recover the bioactivity of the mixed culture. The results indicate that the improvement of biohydrogen yield by mesoporous Fe 3 O 4 was obvious larger than that by ferrous ions. The maximum yield of cumulative hydrogen production was obtained at the mesoporous Fe 3 O 4 nanoparticles of 400 mg·L -1 , which is 26% higher than that of the blank. The lag phases for hydrogen production in the tests added with mesoporous Fe 3 O 4 nanoparticles were decreased to 12 h, which are 50 h less than those of the corresponding ferrous ions and blank tests.
