Hydrogen gas (H2(g))
production is one of the major topic of the industry and energy production
fields, for the last decades. Especially it is popular with showing high energy
density. Among the other industrial methods electrolysis is the cleanest one
without any by product emissions. It has been very popular to recovery of the
discarded materials (such as batteries) as an environmentally friendly
equipments. Here the coal of a used up battery is utilized as an electrode in
the electrolysis system in order to produce (H2(g)). Then these
electrodes were modified with impregnation of Zr and Ce metals. At first, HNO3(aq) and
H2SO4(aq)
solutions were compared as electrolytes with plain electrodes and H2SO4(aq) is
defined as the optimum electrolyte medium (maximum H2(g) production
densities as 24.10xE-5 mL sec-1 and 87.22xE-5
mL sec-1,charge densities as 1137.40xE-4 C sec-1
and 2976.19xE-4 C sec-1 and current densities as 45.68xE-7
i sec-1 and 165.34xE-7 i sec-1 for 0.10 M HNO3(aq) and
H2SO4(aq)
solutions respectively). Then all of these modified electrodes were utilized to
the electrolysis system and compared in the case of H2(g) production
yield, charge and current density values. The best performances were obtained
from Ce modified electrode (maximum H2 (g) production density as
125.00xE-5 mL sec -1, charge density as 4265.24xE-4
C sec-1 and current density as 236.96xE-7 i sec-1 in 0.10 M of H2SO4(aq)
electrolyte). Hydrogen is one of the most promising, clean and sustainable
energy carrier, that can be produced effectively by the usage of Ce modified
battery coal.
