Construction of novel hybrid Z-scheme Agx/WO3@CdS decorated g-C3N4 heterojunction as composite photocatalyst for efficient degradation of organic dyes
Novel hybrid composite of Z-scheme of Agx/WO3@CdS decorated g-C3N4 heterojunction with adjusted morphology of Ag were facilely constructed via thermal-induced self-polymerization, then followed by sol-gel coprecipitation of Agx/WO3@CdS decorated g-C3N4. The nanocomposites were characterized using instrumental characterizations, e.g., XRD, SEM, energy-dispersive X-ray (EDX), HR-TEM with elemental mapping, FT-IR, Raman spectroscopy, and UV-DRS analyses. Results revealed that g-C3N4 and g-C3N4@WO3@CdS NCs have better photocatalytic properties and stability. This observation was achieved through the addition of Ag to NCs. Under visible light irradiation, g-C3N4@1 %Ag/WO3@CdS NCs outperformed the g-C3N4 sample in terms of photocatalytic activity, degrading 98.30 % (0.08539 min−1) of Fluorescein (FS) and 95.36 % (0.0332 min−1) of Congo Red (CR) at 50 and 70 min, respectively. Under the attack of active species like O2•− and •OH, the target pollutants can be oxidized deeply to harmless inorganic compounds.
期刊介绍:
The Journal of Physics and Chemistry of Solids is a well-established international medium for publication of archival research in condensed matter and materials sciences. Areas of interest broadly include experimental and theoretical research on electronic, magnetic, spectroscopic and structural properties as well as the statistical mechanics and thermodynamics of materials. The focus is on gaining physical and chemical insight into the properties and potential applications of condensed matter systems.
Within the broad scope of the journal, beyond regular contributions, the editors have identified submissions in the following areas of physics and chemistry of solids to be of special current interest to the journal:
Low-dimensional systems
Exotic states of quantum electron matter including topological phases
Energy conversion and storage
Interfaces, nanoparticles and catalysts.
