Boosting surface basicity of In2O3 aerogel for high-performance H2S sensors via an in-situ annealing strategy of carbon-composited In(OH)3

Key Points

• The enhanced surface basicity leads to a notable increase in H2S sensor performance.
• Key evidence shows an improvement of up to 50% in response time compared to untreated samples.
• Assessment used a novel annealing strategy with carbon-composited In(OH)3 as a precursor.
• These findings highlight the potential for better gas sensing applications, supporting future research directions.
