Evaluation of Aliphatic Alcohols for CO2 Capture Using the Characteristic Carbonate Frequency.

Control over CO2 capture and utilization are important scientific and technological challenges. Although a variety of amine absorbents are used for capture, releasing the captured CO2 is often difficult and limits their recyclability. Therefore, it is crucial to control the strength of the CO2 bond with the absorbent.

Calibrating the Oxidative Capacity of Microdroplets.

Recently, redox chemical transformations have been reported to occur spontaneously in microdroplets. The origins of such novel reactivity are still debated, and any systematic correlation of the oxidative/reductive yield with the reactivity of the reactant is yet to be established. Towards this end, we report the simple, outer-sphere, one-electron oxidation of a series of ferrocene derivatives spanning a range of oxidation potentials from -0.

Photoinduced Carbon Dioxide Release via a Metastable Photoacid in a Nonaqueous Environment.

Capturing carbon dioxide (CO) from the atmosphere is a scientific and technological challenge. CO can be captured by forming carbamate bonds with amines, most notably monoethanolamine (MEA). Regenerating MEA by releasing captured CO requires that the carbamate solution be heated.

Inferring the Energetics of CO-Aniline Adduct Formation from Vibrational Spectroscopy.

Control of atmospheric CO is an important contemporary scientific and engineering challenge. Toward this goal, the reaction of CO with amines to form carbamate bonds is an established method for CO capture. However, controllable reversal of this reaction remains difficult and requires tuning the energetics of the carbamate bond.
