An in situ infrared cell capable of studying reactions over heterogeneous catalysts in the temperature range 77 to 773 K has been designed. In particular, the adsorption of formic acid on a model Cu/SiO2 methanol synthesis catalyst was investigated. Exposure of a reduced copper surface to formic acid at 300 K resulted in the formation of both formic acid molecules, which were ligated to the copper catalyst, and chemisorbed bidentate copper formate species. Under temperature-programming conditions, the bidentate species displayed a maximum rate of desorption at 433 K, which correlates to a desorption activation energy of 120 kJ mol−1. In contrast, on the reoxidized catalyst, unidentate formate species were preferentially formed. These exhibited a maximum rate of desorption at a temperature of 408 K, and a desorption activation energy of 113 kJ mol−1. A mechanism was postulated to explain this behavior, and evidence was presented to show that useful kinetic data can be obtained for desorption from a catalyst in the form of a pressed disk.

Hydrogen Carrier

Photoreduction of carbon dioxide is one of the promising method to reduce green house gas emission. Carbon dioxide can be converted into organic chemical that has higher economic value by utilizing light energy. One of the favorable product is formic acid which is can be used as hydrogen-carrier. For this process, photocatalyst plays important role as it can increase the rate of reaction and as well as the selectivity as such more desirable product can be produced. The objective of present study is to develop photocatalyst which can significantly catalyze the photoreduction process of CO2 to form formic acid. Zinc titanate doped with aluminium is used as the base photocatalyst. Photoreduction process is held in room condition using three 2800 lm lamp. Qualitative analysis of the product is done by silver solid test and acidity test while quantitative analysis is done by High Performance Liquid Chromatography (HPLC) test. The silver solid test results confirm that formic acid is formed during process. Based on acidity profile data, anthocyanin as photosensitizer could increase higher acidity in the mixture than melanin. However, the concentration of formic acid in the solution is still very low so that it cannot be detected by HPLC.
