Nithiya Jeromiyas, et al., " Anti-poisoning electrode for real-time in-situ monitoring of hydrogen sulfide release" Sensor and Actuators B: Chemistry 7 (10), 2020, 128844. Electrode poisoning and interferences from complex biological environments are major challenges in the development of in-situ H 2S sensors. To circumvent these issues, herein a robust electrode based on reduced graphene oxide-molybdenum disulfide nanohybrid (RGO-MoS 2) and polymerized o-phenylenediamine (POPD) is developed. The POPD/RGO-MoS 2-modified electrode catalyzed H 2S oxidation at a minimized overpotential (+ 0.15 V
