Abstract

A hybrid film composed of reduced graphene oxide (rGO) and molybdenum disulfide (MoS₂) nanosheet-assemblies has been fabricated for high-performance formaldehyde (HCHO) detection, by a simple layer-by-layer self-assembly (LBL SA) method. The rGO/MoS₂ hybrid films not only show improved sensitivity to HCHO at room temperature compared to solely rGO or MoS₂ films, but also exhibit fast response characteristics and good reproducibility. The synergetic effects of rGO and MoS₂ on HCHO sensing enhancement of the hybrid films are attributed to the energy level matching among rGO, MoS₂ and HCHO, which lead to a two-stepped efficient electron transfer from HCHO to rGO.
