V2C MXene modified ZIF-8 for photocatalytic CO2 conversion to Fuel

Azmat Ali KHAN, Muhammad TAHIR

Abstract. The fabrication of highly proficient photocatalysts for CO₂ reduction to fuels is important for solar-to-fuel energy conversion. ZIF-8, a Zn-based metal-organic framework (MOF), owing to large surface area, porous structure, and tunable pore environment turns it into efficient photocatalyst. However, the photocatalytic performance of ZIF-8 is hindered by charge carriers recombination, making it crucial to improve the charge carrier transfer for improved efficiency. Vanadium Carbide (V₂C) MXene, owing to high electrical conductivity, and tunable surface terminations, offer great potential as an electrons reservoir in photocatalytic systems. In this work, a V₂C/ZIF-8 hybrid photocatalyst was fabricated for photoreduction of CO₂ to fuels. The synergistic integration of V₂C with ZIF-8 improved CO₂ capture, facilitated charge separation, and promote multi-electron transfer pathways. The 15% V₂C/ZIF-8 composite achieved a CO yield of 12.23, 0.32 and 2.0 μmol·g⁻¹·h⁻¹ under simulated sunlight for CO, CH4 and H2 respectively. This enhancement is attributed to the high CO₂ adsorption of ZIF-8 coupled with the metallic conductivity in V₂C, enabling efficient the formation of efficient Schottky junction. This work highlights the promising potential of MXene/MOF hybrids for solar-driven CO₂ conversion into value-added fuels.
