| 中文摘要 | a novel strategy for simultaneous removal of cyanide anions and copper cations was proposed. firstly, tio2@yeast hybrid microspheres with raspberry-like structure were fabricated by a facile hydrolysis method using titanium tetrachloride as ti precursor. the physicochemical properties of the as-prepared samples were fully characterized. the bi-functional composites were then employed for the simultaneous removal of a typical mixture of cyanide and copper metal ions via bio-adsorption in dark and photo-catalysis under uv irradiation. the results showed that the satellitic tio2 nanoparticles within the tio2@yeast raspberry-like structure functioned as the photocatalytic active sites providing the electron/hole pairs, while the yeast cores worked as the adsorbent to capture the cyanide and copper ions onto the photocatalytic active sites. the synergistic effects of the bio-adsorption by yeast and photo-catalysis by the tio2 nanoparticles over the bi-functional composites were demonstrated. our results are expected to be of significant value for various environmental friendly applications. |
