Photocatalytic Study on Fe/Ti02 for Solar Hydrogen Generation

Hydrogen gas acts as a versatile energy carrier with potential for extensive use in
power generation, electricity and in many other applications. Hydrogen is a clean
and high energy content fuel (120 MJ/kg), which is three times higher than
hydrocarbon fuels. Heating value ( 61, 100 Btu/lb) of hydrogen is nearly three
times that of methane (23,879 Btu/lb) (Saratale et al., 2008). As shown in Figure
1.2, the energy output from the combustion of hydrogen is considerably greater
than from other sources of hydrogen-containing fuels. It can be seen that only
solar-hydrogen offers the dual capacity of hydrogen fuel with zero CO2 emissions
