Abstract

Abstract: W/O type Pickering emulsion stabilized by alkyl silane grafted nitrogen doped titanium dioxide (s-N-TiO₂) nanoparticles was used as micro-bioreactor for producing ammonium carbonate from carbamide by catalytic action of urease.Effect of amount of nitrogen doped on formation of the emulsion and the visible-light-responsive performance were studied.The results show that under the irradiation of visible light,surface of the s-N-TiO₂ nanoparticles changes from hydrophobic to hydrophilic and coalescence of micro drops of the emulsion as well as the enzymatic reaction in the drops can be triggered.

Key words: nitrogen doped TiO₂ nanoparticles, Pickering emulsions, visible-light responsive, enzymatic reaction
