研究目的
To develop a convenient way to synthesize carbon doped WO3-x ultrathin nanosheets for photocatalytic aerobic oxidation of amines to imines under visible light irradiation at room temperature.
研究成果
The carbon doped WO3-x ultrathin nanosheets exhibit excellent photocatalytic activity and selectivity toward the aerobic oxidation of amines to corresponding imines under visible light irradiation at room temperature, attributed to rich oxygen-vacancies and carbon doping.
研究不足
The study focuses on the photocatalytic activity under visible light irradiation at room temperature, and the stability of the catalyst after multiple cycles was not extensively explored.
1：Experimental Design and Method Selection:
An acid-assisted one-pot process was developed to synthesize carbon doped WO3-x ultrathin nanosheets.
2：Sample Selection and Data Sources:
Na2WO4?2H2O was dissolved in deionized water with Span 60, followed by addition of concentrated sulfuric acid.
3：List of Experimental Equipment and Materials:
Three-necked round-bottom flask, condenser, LED lamp (λ > 400 nm,
4：5 W·cm?2), gas chromatography spectrometry (GC 9720, Fuli, China). Experimental Procedures and Operational Workflow:
The reaction mixture was heated at 160 oC for
5：0 h, then cooled, washed, and dried. Data Analysis Methods:
The resultant solution was analyzed by gas chromatography spectrometry using benzonitrile as the internal standard.
