Human exposure risks to airborne pollutants, bacteria and viruses in confined spaces have attracted tremendous attention It is a challenge to degrade these harmful materials over a single device by electrical method other than conventional thermal method We fabricated an air cleaning device based on a conductive Ag-Co3O4 coating with Ag nanoparticles on a glass fibre cloth (GFC) The device possessed good flexibility and high permeability of the GFC Powered by low-voltages ( 90% were achieved The electrically treated device completely killed Escherichia coli and Staphylococcus aureus and SARS-CoV-2 pseudovirus within a few minutes at a low surface temperature of &lt; 50 °C The excellent efficiency of the devices was attributed to the confinement of electric power to the coating The device can serve as a flexible filter for air cleaners or conditioners to ensure that human health is maintained amid the pandemic
Low-voltage driven Ag-Co3O4 textile device for multifunctional air cleaning
