Facile one-pot synthesis of Au nanoparticles decorated porous α-Fe2O3 nanorods for in situ detection of VOCs

Abstract

Porous Au/α-Fe₂O₃ NRs are one-pot synthesized, and used as gas sensors for in situ VOCs detection. The sensor shows four times higher response to C₆H₆ than a pure α-Fe₂O₃ sensor and short response/recovery time (<30 s), which may be useful to establish an effective C₆H₆ real-time monitoring system in environmental protection and oil reservoirs' prediction.
