Controllable Chemical Vapor Deposition Growth of High-Mobility Bi₂O₂Te Nanosheets

Air-stable bismuth oxychalcogenides (Bi2O2X) have exhibited exceptional electrical properties and ultrahigh mobility in high-performance electronic devices. However, although Bi2O2Se is commonly used, there have been few reported uses of Bi2O2Te because of its challenging preparation process. This study aimed to synthesize two-dimensional Bi2O2Te nanosheets using the chemical vapor deposition method. Bi2O2Te nanosheets with different thicknesses were obtained by adjusting the growth conditions, such as temperature. The as-prepared Bi2O2Te single crystal exhibited a Hall mobility of 496 cm2 V–1 s–1 at 300 K, which reached 5000 cm2 V–1 s–1 at 2 K. The results expand the Bi2O2X family and show Bi2O2Te to be a promising candidate for use in highly efficient electronic devices

CuO Promotes the Formation of Halogenated Disinfection Byproducts during Chlorination via an Enhanced Oxidation Pathway

Previous studies showed that cupric oxide (CuO) can enhance the formation of trihalomethanes (THMs), haloacetic acids, and bromate during chlorination of bromide-containing waters. In this study, the impact of CuO on the formation kinetics and mechanisms of halogenated disinfection byproducts (DBPs) during chlorination was investigated. CuO does not enhance the formation of DBPs (i.e., 1,1,1-trichloropropanone, chloroform, and trichloroacetaldehyde (TCAL) /dichloroacetonitrile) during chlorination of acetone, 3-oxopentanedioic acid (3-OPA), and aspartic acid, respectively. This indicates that the halogen substitution pathway cannot be enhanced by CuO. Instead, CuO (0.1 g L–1) accelerates the second-order rate constants for reactions of chlorine (HOCl) with TCAL, citric acid, and oxalic acid at pH 8.0 and 21 °C from –1 s–1, respectively. Oxidation pathway predominates based on the quantification of oxidation products (e.g., a trichloroacetic acid yield of ∼100% from TCAL) and kinetic modeling. CuO can enhance the formation of DBPs (e.g., THMs, haloacetaldehydes, and haloacetonitriles) during chlorination of model compounds and dissolved organic matter, of which both halogen substitution and oxidation pathways are required. Reaction rate constants of rate-limiting steps (e.g., citric acid to 3-OPA, aromatic ring cleavage) could be enhanced by CuO via an oxidation pathway since CuO-HOCl complex is more oxidative toward a range of substrates than HOCl in water. These findings provide novel insights into the DBP formation pathway in copper-containing distribution systems
