Direct electrochemical sensing of ethanol gas by utilizing air/water interface at platinum nanohole array electrode

Key Points

• Detection of ethanol gas improves using a platinum nanohole array electrode, enhancing sensitivity and response time.
• Analysis shows a significant increase in response to ethanol concentrations as low as 1 ppm, indicating high sensitivity.
• The method utilizes the air/water interface which maximizes the interaction of ethanol with the electrode surface for better detection.
• Enhancements could lead to broader applications in gas detection; however, field testing is necessary to confirm reliability.
