Synthesis of nanocrystalline ZnS/TiO2 films for enhanced NO2 gas sensing

Au/ZnS/ZnO Photoelectrochemical Sensor for Sensitive and Selective Cd2+ Detection

“…The (111), ( 200) and ( 220 16 Figure 5e shows S 2P 3/2 and S 2p 1/2 peaks at 161.4 and 162.6 eV indicative of S 2− and ZnS. 17 CV is performed in 1 M KOH with Au/ZnS/ZnO as the working electrode, platinum electrode as the counter electrode, and saturated calomel as the reference electrode. Figure 6a displays the CV results of Au/ZnS/ZnO at a scanning rate of 50 mVs −1 in the voltage window of 0 − 0.8 V under different conditions: no Cd 2+ added, no ultraviolet irradiation, Cd 2+ added, ultraviolet light irradiation, as well as Cd 2+ added together with ultraviolet light illumination.…”

Synthesis, modification and application of titanium dioxide nanoparticles: a review

“…6 Thus, remarkable efforts have been directed towards searching for efficient and stable semiconductors. 152–154 However, the chemical instability in an open environment is a crucial problem, especially in highly acidic or alkaline electrolytes. Therefore, an effective protection layer is worthy of investigation.…”
