Abstract
This study is dedicated to advancing phosphorene-based sensors for hydrogen detection. Through the strategic functionalization of phosphorene with urea, the sensor exhibits enhanced performance and exceptional stability in ambient air, making it well-suited for various applications. Extensive characteri-zation techniques confirmed material stability and demonstrated the sensor's high sensitivity (up to 700 ppm) and selectivity for hydrogen at room temperature. The use of operando diffuse reflectance infrared Fourier transform provided real-time insights into the gas sensing mechanism, contributing to a deeper understanding of its operational principles.
