Copper nanoparticles–enzyme biohybrid is a promising material for the remediation of contaminated waters, but its function is influenced by its effect on degradation organic pollutants. This study is the first investigation into the fast degradation of a high amount of Bisphenol A (BPA) in water at neutral pH and room temperature. Four different CuNPs biohybrids with different cu species and nanoparticle sizes were used as catalysts. The biohybrid CuNPs@CALB-3, which contained Cu2O nanoparticles of around 10 nm size, showed excellent catalytic performance removing >95% BPA content (45 ppm) in an aqueous solution in 20 min in the presence of hydrogen peroxide at pH 8 using 1.5 g/L of a catalyst. The catalyst showed excellent stability and recyclability at these conditions.

The almost monodisperse cobble-like CeO2 nanostructures with many pores and a diameter of 50-100 nm have been successfully synthesized by a smart hydrothermal route. XRD, SEM, XPS, BET, and in situ DRIFT were employed to characterize the samples. The results showed that the cobble-like CeO2 owned a fluorite cubic structure and there are Ce3+ ions and oxygen vacancies in surface of samples. Its catalytic activity was investigated by selective catalytic reduction of NOx with NH3. The results showed that cobble-like CeO2 nanostructures exhibit excellent catalytic performance, which can be attributed to the much larger surface areas, novel morphology and the best redox behaviour of surface oxygen on the CeO2 surface.
