Ultrafast, one-step laser-induced in-situ transformation of MoS2 into α-MoO3 microribbons for high-performance triethylamine gas sensing

Key Points

• Enhanced gas sensing performance is observed with alpha-MoO3 microribbons, indicating a strong response to triethylamine.
• The transformation from MoS2 to alpha-MoO3 occurs using a one-step, ultrafast laser process, optimizing efficiency.
• This process streamlines the preparation of gas sensors by directly creating high-performance microribbons from MoS2.
• Future applications in environmental monitoring may benefit from this efficient method of producing gas sensors.
