Abstract

Vanadium dioxide (VO₂) is a promising material for smart windows due to its metal-insulator transition that enables dynamic solar transmittance modulation. In this study, VO₂ (M) nanoparticles were synthesized using a novel approach involving the self-supported structure of V₄C₃ MXene derived from V₄AlC₃. Through selective etching, solvothermal oxidation and annealing, VO₂ (M) nanoparticles with enhanced thermochromic properties were produced. The self-supported structure of V₄C₃ MXene significantly reduced particle agglomeration and improved crystallinity, resulting in VO₂ (M) films with a luminous transmittance (T_lum) of up to 58.3% and a solar modulation ability (ΔT_sol) of 6.3%. The study also demonstrated that film thickness and hydrogen peroxide concentration critically influence optical and thermochromic performance. This study provides a new approach for the preparation of MXene-based VO₂ thermochromic smart window materials and is expected to promote their application in the field of building energy conservation.
