Sensitive and selective NiFe 2 O 4 -based gas sensor for hazardous hydrogen sulfide (H 2 S) monitoring

Key Points

• To develop a highly sensitive and selective gas sensor for the detection of hydrogen sulfide (H2S).
• Synthesis of NiFe2O4 spinel nanoparticles
• Testing of gas sensing performance at 200 °C
• Measurement of detection limits for H2S gas
• Fast detection of H2S gas observed
• Low detection limit achieved
• Selective response to H2S at elevated temperatures
