TL;DR: In this article, the photocatalytic activity for NO removal under an oxidative atmosphere has been studied over commercial TiO 2 and plasma-treated TiO2 powders, where NO 3 − was accumulated.

TL;DR: The surface area of graphitic carbon nitride (g-C3N4) obtained by heating melamine at 550 °C was only 7.7 m2 g−1, which was too small for it to be utilized as a catalyst for air purification.

TL;DR: In this paper, the authors introduced a dimensionless parameter Λ that describes the criteria for a direct interaction between nonthermal plasma and catalysts, and several lines of experimental evidences on the interaction were introduced: discharge mode, formation of metal cluster ions, and plasma-induced fluorescence from the catalyst.

TL;DR: An anatase type of TiO2 photocatalyst containing N atoms was synthesized by a new technique using a complex of Ti4+ with a nitrogen-containing ligand as a precursor as discussed by the authors.

TL;DR: Investigation of photocatalytic degradation of the three pesticides acephate, dimethoate, and glyphosate in water using UV light and TiO2 immobilized on silica gel as photocatalyst shows rapid destruction of the pesticides into harmless byproducts using the UV/TiO2 system.
