Controlling Crystallinity and Porosity of Covalent Organic Frameworks with Hydrogen Bonding

This work reports a solvent-free solid-to-solid synthesis method for covalent organic frameworks (COFs), which is very promising from a greener and cleaner chemistry standpoint. The researchers found that hydrogen bonding within the starting material plays a key role on the porosity and crystallinity of the final COF.

Structure-Function Relationship in a Highly Efficient CO2 Reducing MOF

A structure-function relationship has been established for a cobalt containing Metal Organic Framework (MOF) that catalyzes carbon dioxide reduction very efficiently. It has been established that the hydroxyl groups coordinated to the metal co-operates to enhance the catalysis by forming H-bond network with CO2. Let’s learn how the authors performed a systematic and thorough investigation on these MOFs.

Bicarbonate Controlling the Rate of CO2 Reduction

This work shows that bicarbonate (HCO3-) is neither a general acid nor a reaction partner in the rate-limiting step of electrochemical CO2 reduction catalysis mediated by planar polycrystalline Au surfaces. Kinetic modeling studies and electrochemical experiments suggest that it acts as a proton donor in steps past the rate-limiting one and a buffer in the solution.
