Alkali-metal-oxides coated ultrasmall Pt sub-nanoparticles loading on intercalated carbon nitride: Enhanced charge interlayer transportation and suppressed backwark reaction for overall water splitting

Zhenxing Zeng, +6 more
- 01 Sep 2019 - 
TL;DR: In this article, the authors demonstrate the clever design and construction of an alkali-metal-oxides membrane coated ultrasmall Pt sub-nanoparticle that is deposited on the intercalated carbon nitride for efficient overall water splitting.
Journal ArticleDOI

C60 aminofullerene-magnetite nanocomposite designed for efficient visible light photocatalysis and magnetic recovery

Yeoseon Choi, +10 more
- 01 Apr 2014 - 
TL;DR: In this paper, a magnetically recyclable photosensitizing system for harnessing solar energy for water treatment and disinfection is reported, which comprises C60 aminofullerene as a sensitizer for singlet oxygenation and functionalized mesoporous silica (msu-f SiO2) encapsulating magnetite nanoparticles (msu-SiO2/mag) as magnetically separable host.
Journal ArticleDOI

Titania sol, method of preparing the same, and coating composition comprising the same

Sang Hyuk Im, +3 more
TL;DR: In this article, a titania sol was prepared by elevating the temperature of a reactant solution including a precursor of titania in a solvent for reaction to a reaction temperature.
Journal ArticleDOI

Nitrite-Induced Activation of Iodate into Molecular Iodine in Frozen Solution

Kitae Kim, +8 more
- 27 Mar 2019 - 
TL;DR: The freezing-induced production of I2 in the presence of IO3- and NO2- was observed under various conditions, which suggests this abiotic process for I2 production is not restricted to a specific region and occurs in many cold regions.
