| Description |
Sensitive and non-enzymatic electrochemical hydrogen peroxide (H2O2) sensor was fabricated using molybdenum disulphide (MoS2)-Interconnected porous carbon (ICPC) heterostructure. The structural properties of
synthesized MoS2, ICPC and MoS2-ICPC materials were examined by various spectroscopy and microscopy
techniques. These results confirmed that the support matrix play a crucial role for the formation of different size
of MoS2. The structure of MoS2 altered to nanosized while growing on the support matrix. The electrochemical
H2O2 sensing characteristics of MoS2-ICPC composite material exhibited superior activity than individual MoS2
and ICPC materials. The results concluded that the interconnected porous carbon might stimulate the structural modification of MoS2 with enhance exposed active edge sites, which is responsible for higher electrochemical activity. The composite material exhibited a detection limit of 11.8 μM H2O2 with higher sensitivity, selectivity, and long-term stability. These results open a novel way to build MoS2-ICPC material for active electrochemical sensor applications
