Abstract :
We demonstrated a flexible and transparent benzene sensor using cobalt-metalloporphyrin (Co-MPP)-functionalized few-layer MoS2 as sensing material for the first time. The sensor detected benzene down to 10 ppm at room temperature. The functionalization with Co-MPP catalysts enhanced sensitivity (ΔR/R0) over 250% compared to pristine MoS2. The fabricated sensor showed good mechanical flexibility and optical transparency, which is advantageous for a wide variety of chemical sensing applications.
