Carbon modification endows WO3 with anti-humidity property and long-term stability for ultrafast H2S detection

Sensitive and selective determination of H2S has been widely reported. However, its gas sensing performance is vulnerable to some special environments such as high humidity. Especially, the sluggish response/recovery time and the unfavorable long-term stability are the main obstacles for H2S gas sensing. Herein, carbon modification on coral-like WO3 with bimodal pore distribution (mesopores and macropores) has been fabricated by one-step...
