摘要：A novel polymeric support for heterogeneous photocatalytic reactions was fabricated by using a multiple O/W/O emulsion as the template, which was an open-cell macroporous bead with photocatalyst titanium dioxide (TiO2) nanoparticles embedded in the void surface. The beads exhibited high photocatalytic efficiency, up to 99.4 % methyl orange could be degraded in 2.5 h photocatalysis in the water containing the bead of 0.46 wt%. Moreover, stable cyclic usage in wastewater treatment was proved to be feasible, and not any decrease in the photocatalytic performance was found for the use in their later 9 cycles, which make the bead material an ideal and potential photocatalyst in wastewater industry.
