The Bi2MoO6 nanoplates were syn‑ thesized from Bi(NO3)3·5H2O and ( NH4)6Mo7O24·4H2O via a hydrothermal method, leading to the presence of amino group on the surface of Bi2MoO6 nanoplates and thus posi‑ tively charged. The synthesized B i2MoO6 displays irregu...
Pure Bi2WO6was formed by the hydrothermal technique. To begin, 80 mL of D.W. was dissolved with 2 mmol of Bi(NO3)3.5H2O, 1 mmol of Na2WO4.2H2O, and 0.05g of [CTAB]. The final solution was stirred using a magnetic stirrer at room temperature for 30 min and adjusted to pH 7. ...

Synthesis of Bi2S3and C@Bi2S3 To develop the final C@Bi2S3, the Bi2S3was initially synthesized as described below using a modified hydrothermal method from previously reported literature28. In detail, Bi(NO3)3·5H2O (0.2 M) is dissolved in 25 mL of deionized (DI) water in a...
A typical process is as following: 0.97 g Bi(NO3)3?5H2O and 0.33 g Na2WO4?2H2O were dissolved in 40 ml ethylene alcohol, after being stirred for 6 h, the transparent solution was added into a 50 ml Teflon-lined autoclave up to 80% of the total volume. Then the autoclave was ...
