CO2 PHOTOREDUCTION TO PRODUCE FORMIC ACID

According to Global Carbon Project, the CO2 emission for 2018 has reached a new record of 37.1 billion metric ton. This figure is higher than those of previous years. The carbon dioxide emission has been a primary issue to address because it absorps infrared radiation and subsequently rises the a...

The carbon dioxide emission has been a primary issue to address because it absorps infrared radiation and subsequently rises the atmospheric temperature.

Although the brief mechanism of photosynthesis is reducing carbon dioxide to glucose, there exists a need to reduce carbon dioxide to formic acid first. Because such artificial photosynthesis is executed at room temperature, atmospheric pressure, and under direct sun light, this reaction requires photosensitizers to enable the solar energy to reduce carbon dioxide. Aside from reducing the carbon dioxide emission, this pathway is also able to convert it to valuable compound, which is formic acid, whose application in energy is a Liquid Organic Hydrogen Carrier (LOHC). This explorative research is aimed to photocatalytically reduce CO2 with Zn6Cr2(OH)16CO3.4H2O concocted with varied drying time. The photocatalyst has 51.3% crystalinity and is theoretically active with red to orange visible light. Literature study shows that Zn is a metal commonly found in carbonic anhydrase and Cr in formate dehydrogenase, enzymes responsible for photosynthesis and reversible conversion of carbon dioxide to formic acid, which implies that both are metals promising in photocatalytic reduction of carbon dioxide to formic acid. text
