TL;DR: Results indicate that radical intermediates such as sulfate radical anion and hydroxyl radical are not majorly responsible for this persulfate-driven oxidation of organic compounds, and suggest that G-ND plays a critical role in mediating facile electron transfer from phenol to persulfates.

TL;DR: In this paper, the authors highlight the interfacial and interparticle CTs under the bandgap excitation of TiO2 particles, visible light-induced photochemical processes via either dye-sensitization or ligand-to-metal CTs at surface modified TiO 2 particles, and the applications of the photoprocesses to pollutant degradation and simultaneous hydrogen production.

TL;DR: In this paper, size controlled nanographene oxides (NGOs; <50 nm) were prepared by a two-step oxidation process and NGOs were self-assembled with TiO2 nanoparticles to form the core/shell structure.

TL;DR: This study elucidates the mechanism behind persulfate activation by exploring the role of various oxyanions in two activation systems utilizing iron nanoparticle (nFe0) as the reducing agent and single-wall carbon nanotubes (CNTs) as electron transfer mediators.

TL;DR: In this article, the CdS-TiO2-WO3 ternary hybrid was successfully synthesized and characterized for the structural, optical, and morphological properties by X-ray diffraction, diffuse reflectance UV/visible absorption spectroscopy, high-resolution transmission electron micrography, and energy-dispersive X -ray analysis.
