High electrocatalytic activity of Pt on porous Nb-doped TiO₂nanoparticles prepared by aerosol-assisted self-assembly

Abstract

A niobium-doped titanium dioxide electrocatalyst support for proton-exchange membrane fuel cells was prepared by an aerosol-assisted method and then loaded with platinum nanoparticles in the presence of ethylene glycol as a reducing agent.

Reactive species specific RhB assisted collective photocatalytic degradation of tetracycline antibiotics with triple-layer Aurivillius perovskites

“…S16, ESI†) observed at g = 2.0023 is attributed to bridging oxygen vacancies (Ti 4+ –O–O˙) on the surface. 74,75 The sample (catalyst dispersed in distilled water) after irradiation with light did not show any additional EPR signal. However, the intensity of the above signal decreased drastically when the sample was dispersed in RhB solution.…”
