The Impact of pH and Irradiation Wavelength on the Production of Reactive Oxidants during Chlorine Photolysis.

Environmental Science and Technology, 2019
Chlorine photolysis is an advanced oxidation process which relies on photolytic cleavage of free available chlorine (i.e., hypochlorous acid and hypochlorite) to generate hydroxyl radical, along with ozone and a suite of halogen radicals. Little is known

Autocatalytic Decomplexation of Cu(II)-EDTA and Simultaneous Removal of Aqueous Cu(II) by UV/Chlorine.

Environmental Science and Technology, 2019
Traditional processes usually cannot enable efficient water decontamination from toxic heavy metals complexed with organic ligands. Herein, we first reported the removal of Cu(II)-EDTA by a UV/chlorine process, where the Cu(II)-EDTA degradation obeyed ...

Achieving high open-circuit voltage on planar perovskite solar cells via chlorine doped tin oxide electron transport layers.

ACS Applied Materials and Interfaces, 2019
The open-circuit voltage deficit is one of the main limiting factors for the further performance improvement in planar structured perovskite solar cells. In this work, we elaborately develop chlorine binding on the surface of tin oxide electron transport

Reactivity of Enveloped Virus Genome, Proteins, and Lipids with Free Chlorine and UV254.

Environmental Science and Technology, 2018
The survivability of viruses in natural and engineered systems impacts public health. Inactivation mechanisms in the environment have been described for nonenveloped viruses, but it remains unclear how the membrane layer of enveloped viruses influences ...

The roles of reactive species in micropollutant degradation in the UV/free chlorine system.

Environmental Science and Technology, 2014
The UV/free chlorine process forms reactive species such as hydroxyl radicals (HO(•)), chlorine atoms (Cl(•)), Cl2(•-), and O(•-). The specific roles of these reactive species in aqueous micropollutant degradation in the UV/chlorine process under ...

Hydrogen Atom Transfer Reactions via Photoredox Catalyzed Chlorine Atom Generation.

Angewandte Chemie, 2018
The selective functionalization of chemically inert C-H bonds remains to be fully realized in achieving organic transformations that are redox-neutral, waste-limiting, and atom-economical.

Synthesis of Chlorine-Substituted Graphdiyne and Applications for Lithium-Ion Storage.

Angewandte Chemie, 2017
Chlorine-substituted graphdiyne (Cl-GDY) is prepared through a Glaser-Hay coupling reaction on the copper foil. Cl-GDY is endowed with a unique π-conjugated carbon skeleton with expanded pore size in two dimensions, having graphdiyne-like sp- and sp2 ...
