Abstract
Growing energy demand challenges and environmental problems due to fossil fuel consumption have raised awareness in recent decades. Currently, the worldââ¬â¢s energy needs are largely dependent on fossil fuels such as oil, coal and natural gas. World energy consumption is constantly increasing over time with social living standards and industrialization. To solve both most pressing problems; dependence on fossil fuels and climate change, the photocatalytic reduction of carbon dioxide to produce synthetic fuels can be an attractive solution to limit environmental pollution. The conversion of CO2 into value-added chemicals by visible light driven photocatalysis has a great potential. A small amount of the composite was added to the solution of sodium carbonate and then the solution was exposed to visible light to reduce it to formaldehyde. The progress of the reaction was monitored spectrophotometrically using chromotropic acid. The effect of different operating parameters on the formation of formaldehyde was evaluated.
