Enhanced photocatalytic activity and cycle stability driven by ultrasonic vibration for ferroelectric photocatalysts

open access: yesIET Nanodielectrics, 2019
Ferroelectric materials have been applied in the photocatalytic field due to the internal electric field generated by the spontaneous polarisation. In this study, it is found that the ferroelectric BaTiO(3) catalysts exhibit the excellent photocatalytic ...

Photocatalytically active TiO2 – silicone rubber [PDF]

open access: yesAIP Conference Proceedings, 2019
Bacteria are present in all areas of everyday life and can lead to dangerous infections. Surfaces with antimicrobial properties are used to reduce the risk of infection in sanitary facilities and hospitals. Apart from the addition of biocides or antibiotic agents to synthetic materials, recent research show, that it is possible to use the semiconductor

Decoration of titania nanofibres with anatase nanoparticles as efficient photocatalysts for decomposing pesticides and phenols [PDF]

open access: yes, 2012
Using a series of partial phase transitions, an effective photocatalyst with fibril morphology was prepared. The catalytic activities of these materials were tested against phenol and herbicide in water. Both H-titanate and TiO2-(B) fibres decorated with

A simple strategy to simultaneously improve the lifetime and activity of classical iridium complex for photocatalytic water‐splitting

open access: yesAggregate, 2023
Herein, we design and synthesize a series of oligomers [Ir(ppy)2(dabpy)‐ODPA]n (D1‐n) by copolymerization of [Ir(ppy)2(dabpy)][PF6] (D2) with 4,4′‐Oxydiphthalic anhydride (ODPA), to resolve the problem of simultaneous improvement of stability and ...

Chemical vapor deposition and characterization of nitrogen doped TiO2 thin films on glass substrates [PDF]

open access: yes, 2009
Photocatalytically active, N-doped TiO2 thin films were prepared by low pressure metalorganic chemical vapor deposition (MOCVD) using titanium tetra-iso-propoxide (TTIP) as a precursor and NH3 as a reactive doping gas.

Photocatalytic activity of P-doped TiO2 photocatalyst

open access: yesPhotochemical & Photobiological Sciences, 2023
AbstractIn this study, P-doped TiO2 photocatalysts with different molar percentages (in the range 0.071–1.25 mol %) of the non-metallic element were prepared and their photocatalytic activity under visible light irradiation was tested. All achieved samples were characterized by XRD, Raman, UV–Vis DRS and SEM–EDX techniques.
