Insight into the Photocatalytical Activity of TiO2 Nanoparticles Through the Electrochemical Characterization of Carbon Paste Electrodes

Photoelectrochemical and theoretical investigation of the photocatalytic activity of TiO2 : N

In N-doping on TiO₂ nanomaterial occurs a big decrease of band-gap (1 eV); however, its photocatalysis is low. We clarify such fact from effective mass, i.e., the electron–hole recombination is more than creation of electron–hole pair.

Calcination temperature-dependent surface structure and physicochemical properties of magnesium oxide

The electrochemical performance of MgO particles is highly dependent on their crystal structures resulting from calcination at different temperatures.
