Hollow Au@TiO₂ porous electrospun nanofibers for catalytic applications

Abstract

Catalytically active porous and hollow titania nanofibers encapsulating gold nanoparticles were fabricated using a combination of sol–gel chemistry and coaxial electrospinning technique.

Structural design toward functional materials by electrospinning: A review

“…et al(171) reported a kind of catalytic active porous and hollow TiO 2 nanofiber coated with gold NPs by sol-gel chemistry and coaxial electrospinning. The resultant Au@TiO 2 porous hollow nanofibers show good catalytic activity and recyclability.…”

Development of Free-Standing Titanium Dioxide Hollow Nanofibers Photocatalyst with Enhanced Recyclability

“…The small-sized photocatalysts tend to be trapped together in the effluent, which eventually reduces the number of remaining catalysts in the system. Catalysts reclamation procedures such as centrifugation [ 9 ], gravitational sedimentation [ 10 ], and filtration [ 11 ] are also required in order to collect the lost catalysts. In long-term application, this might have an impact on the operational cost and impede the overall performance as the recyclability of the photocatalysts are reduced.…”

Optical Index Matching, Flexible Electrospun Substrates for Seamless Organic Photocapacitive Sensors

“…[35][36][37] Their large specific surface makes them well-suited for diverse applications such as filters, catalysts, bioengineering, tissue engineering, and wearables. [38][39][40][41] For in vivo applications, it is reasonable to use nontoxic or low-toxic solvents for processing, such as dimethyl sulfoxide (DMSO), and polymers which can be dissolved in it. [42] An ideal candidate is polyacrylonitrile (PAN), being unambiguously spinnable from DMSO and not showing cell toxicity.…”
