Conclusion
The aim of this project was to assess favorable nano-photocatalysts with uniform and small size. For this reason, H2acacen was used as a capping agent to prevent agglomeration of products in the solid state process. Several parameters were compared to reach optimum size and uniformity of as-made samples. These factors include calcination time, calcination temperature, and molar ratio of H2acacen. The best size of particle is achieved when ratio of H2acacen to Nd was 2:1 and calcined at 700 °C for 2 h. The influence of different parameters such as type of dye, type of light source, pH and dye concentration on photocatalytic activity of samples were investigated. So, the prepared catalyst shows 77.98% photocatalytic efficiency in degradation of 5 ppm Eriochorome Black T under UV light at pH = 11 which can be promising material to improve the catalytic performance for contaminant. Our findings suggest that the NdVO4 nanoparticles is a potential nano-photocatalysts for dye removal from waste water. Thus, our belief is that the nanosized NdVO4 nanoparticles can be used as a promising photocatalysts in various industries.
