Snowflake-Sharped Pt Modified Cu2O Alloyed Nanoclusters for Photo-Electro Fenton Degradation of Dye Contaminant
Incorporation of the traditional Fenton catalysis technique with other advanced wastewater purification technology is a effective strategy for large-scale water pollution treatment, this potency of co-processing treatment technology on the degradation of organic pollutant effluents is more efficient and preferable. In this study, a innovation based on photothermal enhanced photo-electro Fenton tactics based on alloyed snowflake-sharped Pt modified Cu2O nanoclusters (SSPt-Cu2O NCs) were prepared by using a typical hydrothermal method. The alloying design is conducive to electron transfer to improve catalytic efficiency. Meanwhile, the SSPt-Cu2O NCs have excellent photothermal properties (over 50 oC) to increase the catalytic reaction rate under 808 nm near-infrared (NIR) laser irradiation. Then dyestuff Rhodamine B (RhB) was used as model contaminants to evaluate the degradation capacity of the as-synthesized SSPt-Cu2O NCs by simultaneously append NIR laser (808 nm, 2.0 W•cm-2, 5 min) and direct current (DC, 110 V, 50 Hz, Cv≤1 mvrms CC≤5 mARms). The degradation efficiency for reach up to could reach up to 96.13% in a 2-h treatment procedure by using the photo-electro Fenton catalyst (1.0 mg/mL of RhB, catalyst concentration at 1.0 mg•mL-1, and pH at 7.0). Moreover, the SSPt-Cu2O NCs photo-electro Fenton catalyzers show goodish reusability and outstanding atoxic nontoxicity for environment application, which designating the potential candidate for organic pollutional chemicals in wastewater management.
