Electric Field-Driven Air Purification Filter for High Efficiency Removal of PM<sub>2.5</sub> and SO<sub>2</sub>: Local Electric Field Induction and External Electric Field Enhancement
Removal rate and durability are the two most important parameters of an ideal air purification filter to remove inhalable particles and toxic gases. Here, based on the interaction of a local electric field and an external electric field, a novel coaxial core–shell CuO@NH<sub>2</sub>-MIL-...

| description | Removal rate and durability are the two most important parameters of an ideal air purification filter to remove inhalable particles and toxic gases. Here, based on the interaction of a local electric field and an external electric field, a novel coaxial core–shell CuO@NH<sub>2</sub>-MIL-53(Al) nanowire array was synthesized on a rigid copper net, which was used to remove PM<sub>2.5</sub> and SO<sub>2</sub> simultaneously. The removal rates of PM<sub>2.5</sub> by the filter with and without an external electric field can reach 98.72% and 44.41%, respectively, and the adsorption capacity of SO<sub>2</sub> can reach 4.87 mol/m<sup>2</sup>. After repeated filtration and cleaning for 10 cycles, the air pollution removal efficiency can be kept almost stable. |
