Abstract

Electrochemical reduction can capture and utilize CO2 through its conversion to small chemicals and fuels. Analytical standard operating procedures for the accurate quantification of short-chain acids, aldehydes, and alcohols by high-performance liquid chromatography (HPLC), gas chromatography-mass spectrometry (GC-MS), or NMR are not well established. Electrochemical reduction of CO2 produces the smallest conceivable organic compounds, which necessitates slow NMR quantifications due to slow T-1 relaxation toward equilibrium magnetization. It is shown that the use of paramagnetic contrast agents or cooling of water/DMSO provides T-1-optimized measurements with attractive sensitivity and speed. H-1 NMR experiments that are widely used in the study of biological mixtures are found unsuitable for quantitative analyses of T-1-optimized samples.
