Description
The rising CO2 concentration in the atmosphere has sparked the need for research communities and industries to shift toward embracing technologies prioritizing CO2 conversion and utilization. This research presents the fabrication of flowerlike cobalt-inorganic phosphate-decorated Ti3C2Tx MXene-modified carbon fiber paper (Co-Pi/Ti3C2Tx/CFP) electrode for electrochemical CO2 fixation via benzyl chloride transformation to produce industrially and pharmaceutically important phenylacetic acid (PAA). The multilayered Ti3C2Tx, having a large specific surface area, functions as the nucleation centers for the deposition of Co-Pi and enhances its physical, chemical, and electron transmission attributes. The Co-Pi anchored to Ti3C2Tx in turn modifies the interlayer properties of MXene, prevents restacking of the layered MXene structure, provides additional electrocatalytic sites, and escalates the electrocatalytic efficiency. Cyclic voltammetry and potentiostatic electrolysis studies revealed a higher current response, lower reduction potential, and increased productivity at the Co-Pi/Ti3C2Tx/CFP electrode for benzyl chloride transformation with CO2 coupling, yielding the desired carboxylic acid. Under optimal conditions, potentiostatic electrolysis at ?1.6 V for 8 h yielded up to 62% PAA, following a diffusion-controlled two-electron reduction mechanism. Furthermore, the electrodes showed good repeatability, reproducibility of electrochemical responses, and excellent stability over 60 days. 2025 American Chemical Society
