It is quite popular to support bio-hydrogen production with the use of nanoparticles. There are many types of nanoparticles used in scientific research. Nickel ferrite and cobalt ferrite are the some of these nanoparticles, which are generally used in photocatalytic hydrogen production studies. However, the effect of these nanoparticles on dark fermentation has not been investigated before. This study investigated the effect of nickel ferrite (NiFe2O4) and cobalt ferrite (CoFe2O4) nanoparticles on bio-hydrogen production yield. Hydrogen production performance with pretreated sludge was evaluated using different ratios of nanoparticles. The effect of addition of nanoparticles on dark fermentative bio-hydrogen production evaluated compared to control set.
