A versatile electrospun polylactic acid nanofiber membrane integrated with halloysite nanotubes for indoor air purification, disinfection, and photocatalytic degradation of pollutants

•A nanoclay/polymer photocatalytic electrospun nanofiber membrane was fabricated.•HNTs improve the filtration performance and lifetime for PMs by storing charges.•HNTs inhibit the aggregation of nano-Ag3PO4 and accelerate photocatalytic reaction.•The utilization of nanoclay loaded photocatalyst in air purification was realized.•Both great quality and mass production are accomplished by upgrading machine.
