Abstract
AbstractA new family of two‐dimensional (2D) materials called MXenes has gained attention recently owing to their fascinating physical and chemical properties. Herein, 2D vanadium carbide (V2C) MXene was mixed with cellulose nanocrystals (CNCs) to produce an environmentally friendly V2C/CNC composite. The V2C/CNC composite exhibited surface‐enhanced Raman scattering (SERS) activity for the methylene blue (MB) dye with an enhancement factor of ~9 × 105. Here, we have proposed that along with electromagnetic enhancement, the charge transfer process plays a vital role in the SERS enhancement. We believe that this work would open a new way to fabricate sustainable and renewable MXene and CNC composite solution‐based SERS platforms for analyte detection.
