Simple and eco-friendly synthesis of recoverable zinc cobalt oxide-based ceramic nanostructure as high-performance photocatalyst for enhanced photocatalytic removal of organic contamination under solar light

چکیده مقاله

Organic dyes as remarkable effluents from various industries have caused unwanted environmental contamination. In this investigation, ZnCo2O4-Co3O4 nanostructure was fabricated utilizing a new and green reducer and stabilizer (Phoenix dactylifera extract), for the first time. The nanostructure was employed as a recyclable photocatalyst for degrading organic dyes such as Rhodamine B, Acid Black 1 and phenol red under visible illumination. The photocatalytic yield was highly efficient. A significant factor (dosage of Phoenix dactylifera extract) that affects the shape, dimension, and catalytic yield of ZnCo2O4-Co3O4 product was examined and its optimal quantity was determined. Different techniques were utilized to identify and check the properties of ZnCo2O4-Co3O4 product. The findings revealed that 100, 95.7 and 100% of Rhodamine B, Acid Black 1 and phenol red as target contaminants were degraded utilizing ZnCo2O4-Co3O4 product, respectively, within 75 min under visible illumination. Further, the nanoscale ZnCo2O4-Co3O4 product (produced using Phoenix dactylifera extract) possessed very good stability and recyclability without any noticeable reduction in the catalytic yield up to nine runs. These outcomes suggest that ZnCo2O4-Co3O4 product (produced via Phoenix dactylifera extract) may be an effective kind of recyclable photocatalyst to eliminate environmental contaminants.
