Also, there is a developing need to opt for more environmentally friendly processes to generate more efficient and cleaner bio-fuels. This study purposed to Catalysize bio-slurry degradation to bio-hydrogen and hydrocarbon fuels using an electrolytic solar cell, a 40Watt solar power panel. Design and fabrication of a modified E.B.S.C of capacity [Electrode sections; Height:13cm, diameter:4.91cm, length: 36.10cm, gas collection chamber diameter: 5.30cm, collection tube: 1.27cm] was done. A pre-experimental set-up with a 9,000mL capacity of bio-slurry and a solar energy system of 40W (current of Pmax; vmp of 1.1) was used in order to electrolyze bioslurry. Analysis of the slurry's bio-characteristics revealed presence of bacterial colonies, a total Solid concentration of 14.8mg/L (TSS=13mg/L & TDS =1.8mg/L ), pH of 8.04 (). Geo-catalyst and synthesized iron oxide catalyst were used to lower kinetic energy barrier and enhance the rate of degradation and gas volume production. The gas evolved in the set-up containing ebara electrocatalyst depicted the highest volume followed by the set-up with the iron electrocatalyst with a variation of 50mL difference for some of the days while similar gas collection levels for other days. The control experiment depicted that the two catalyst had an impact in the degradation of the bio-slurry as time went by. References 1. Ajithkumar, A., & PK, S. B. (2022).
