Novel ultralong and photoactive BiTiO/TiO heterojunction nanofibers toward efficient textile wastewater treatment.

The elimination of dyes from textile wastewater with a lower carbon footprint is highly contingent on the design of green catalysts. Here, we innovatively developed ultralong one-dimensional BiTiO/TiO heterojunction nanofibers electrospinning so as to photocatalytically degrade dyes efficiently and sustainably through the utilisation of renewable solar irradiation. The heterostructured BiTiO/TiO nanofibers exhibited desirable activity in the visible light region through the slight shift of the absorption edge to a longer wavelength.

Flexible Hierarchical TiO2/Fe2O3 Composite Membrane with High Separation Efficiency for Surfactant-Stabilized Oil-Water Emulsions.

Globally, efficient oil-water separation for surfactant-stabilized oil-water emulsions has been in urgent demand. The current options available for separation are neither sustainable nor resistant to fouling. Herein, we introduce a hierarchically nanostructured TiO2/Fe2O3 composite membrane, which is capable of separating surfactant-stabilized oil-water emulsions with high separation efficiency.

A self-assembled superhydrophobic electrospun carbon-silica nanofiber sponge for selective removal and recovery of oils and organic solvents.

An oil spill needs timely cleanup before it spreads and poses serious environmental threat to the polluted area. This always requires the cleanup techniques to be efficient and cost-effective. In this work, a lightweight and compressible sponge made of carbon-silica nanofibers is derived from electrospinning nanotechnology that is low-cost, versatile, and readily scalable.
