Fluoride Catalysts and Organic Additives for Conversion of CO2 to Formic Acid and Methanol using Powdered Silicon as Reducing Agent
Asian Journal of Organic Chemistry（2022）
摘要
Abstract The effect of fluoride catalysts and organoboronic acid additives on the reduction of CO 2 using waste silicon wafer powder as a reducing agent was investigated. Compared to other fluorides containing monovalent cations, tetraalkylammonium fluorides show higher catalytic activity for the conversion of CO 2 to formic acid. Arylboronic acid containing electron‐withdrawing groups such as p ‐fluorophenylboronic acid facilitated methanol formation during CO 2 reduction. Electrophilic activation of formic acid by arylboronic acid may promote the reduction of formic acid to methanol.
