Titanium metal-organic frameworks for photocatalytic CO conversion through a cycloaddition reaction.

The elevated levels of CO in the atmosphere have been a major concern for environmental scientists. Capturing CO gas and its subsequent conversion to useful organic compounds is one of the avenues that have been extensively studied in the last decade. The photocatalytic cycloaddition of CO is a promising approach for effective CO capture and the production of value-added chemicals such as cyclic carbonates.

Hexagonal Layer Manganese Metal-Organic Framework for Photocatalytic CO Cycloaddition Reaction.

A novel manganese metal-organic framework (Mn-MOF) termed UAEU-50 assembled from a benzenedicarboxylate linker (BDC) and trinuclear manganese clusters was synthesized and fully characterized using different spectroscopic and analytic techniques (e.g., X-ray powder diffraction, UV-vis diffuse reflectance spectroscopy, thermogravimetric analysis, scanning electron microscopy, and energy-dispersive X-ray spectroscopy).
