Enhanced photocatalytic performance of anatase titania nanotubes via the synergistic effect of trace copper doping and oxygen vacancies

Abstract

In this study, trace of copper element was introduced to anatase titania nanotubes (ANTs) successfully through one-step solvothermal method, also generating more oxygen vacancies in the lattice. The spatial separation...

Photon localization effect and surface oxygen vacancy enhanced photocatalytic nitrogen fixation performance for nanocrystalline titanium dioxide films

“…As one of the most plentiful elements on the earth, nitrogen (N) exists in all living organisms and is an indispensable component of many compounds. 1–4 Although dinitrogen gas (N 2 ) makes up about 78% of the atmosphere, it cannot be directly utilized by the vast majority of animals and plants unless it is fixed. 5 As a major product of nitrogen fixation, ammonia (NH 3 ) has widespread applications in agriculture and industry.…”
