Cellulose-based materials with raman scattering enhancement function are used in SERS sensors for detecting styrene in gases, and this material is being developed using these materials.

Abstract

The invention relates to a cellulose-based material functioning as a surface Raman scattering (SERS) enhanced sensing material for the detection of styrene in gaseous environments, and a method for the production of such material. The SERS-sensing cellulose-based material of the invention comprises a cellulose matrix, a graphene oxide (GO) layer placed on the cellulose matrix, and Au@ZIF8 nanostructures distributed on the GO layer to form an active sensing region, where the Au@ZIF8 nanostructures are core-shell nanostructures consisting of a core of gold (Au) nanoparticles and a shell of a porous ZIF-8 organometallic framework. The SERS-sensing cellulose-based material of the invention is used to detect styrene in gaseous environments via SERS measurement.
