“…Two-dimensional (2D) nano-structures have been considered as chemical sensors for various chemical agents [10][11][12][13][14][15]. Metal oxide semiconductors have been widely used as gas sensing materials due to their low cost, high response value, fast response, and good selectivity.…”

The density functional B3LYP was utilized for scrutinizing the effect of Ti-doping on the sensing performance of a ZnO nano-sheet (ZnONS) in detecting phosgene. Pure ZnONS had a weak interaction with phosgene, and the sensing response (SR) was approximately 9.4. There was an increase in the energy of adsorption (Ead) for phosgene from -5.5 to -22.8 kcal/mol after the doping of a Ti atom onto the surface of ZnONS. Following the doping of Ti, there was also a dramatic increase in the SR to 84.2. The recovery time (RT) for the desorption of phosgene from the ZnONS that was doped with Ti at 298 K was 4.1 s. This suggested that Ti-doped ZnONS might be used as a phosgene sensor with a high sensitivity and a shorter RT.

Objective In order to control NOx in low‐temperature flue gases emitted from non‐power industries and to reduce the preparation cost of denitration catalysts, this study uses inexpensive blast furnace slag as raw material to prepare denitration catalysts. Methods After cooling, drying and grinding, the blast furnace slag becomes a powder with considerable fineness and meets the requirements of activity index, which is called GGBS (ground granulated blast furnace slag). Using GGBS as denitration catalyst carrier, the active components M (M = Fe, Co, Ni, Cu and Ce) are loaded on Mn‐based GGBS catalyst using an impregnation method. Conclusions The effect of different active components on the denitration performance and sulfur resistance of Mn‐based GGBS catalysts is investigated. The results show that the Mn‐Ce/GGBS catalyst has better denitration performance and sulfur resistance. The Mn‐Ce/GGBS catalyst has a significant denitration performance when load ratio is 2:1. The active component Ce improves the denitration performance of the catalyst, reduces sulfur poisoning and extends the life of the catalyst. The SO2 in the flue gas increases the acid sites on the catalyst surface and improves catalyst activity. The larger the ratios of Mn4+/Mn3+, Ce4+/Ce3+ and Oα/Oβ, the stronger the catalyst activity and the better the denitration performance. © 2022 Society of Chemical Industry (SCI).
