CO₂ Conversion to Butene via a Tandem Photovoltaic–Electrochemical/Photothermocatalytic Process: A Co-design Approach to Coupled Microenvironments

ACS Energy Letters, Journal Year: 2024, Volume and Issue: 9(9), P. 4369 - 4377

Published: Aug. 15, 2024

We developed a tandem, unassisted, solar-driven electrochemical and photothermocatalytic process for the single-pass conversion of CO2 to butene using only simulated solar irradiation as energetic input. The two-step involves reduction (CO2R) ethylene followed by dimerization butene. assessed two unassisted setups concentrate in CO2R reactor, achieving concentrations up 5.4 vol% with 1.8% average solar-to-ethylene 5.6% CO2-to-ethylene under 1-sun illumination. When effluent gas stream was passed through oligomerization we generated 600 ppm 3-sun Through analysis this process, identified that presence H2, CO, H2O leads rapid deactivation Ni-based catalyst.
