Journal ArticleDOI
Heterogeneous Catalytic Oxidation of As(III) on Nonferrous Metal Oxides in the Presence of H2O2
TL;DR: In this paper, it was shown that H2O2-induced oxidation of As(III) can be markedly enhanced in the presence of nonferrous metal oxides (e.g., WO3, TiO2, ZrO2) as a heterogeneous catalyst working over a wide pH range in ambient reaction conditions.
Journal ArticleDOI
TiO2 nanodisks designed for Li-ion batteries: a novel strategy for obtaining an ultrathin and high surface area anode material at the ice interface
TL;DR: In this article, a large-scale production of ultrathin TiO2 nanodisks was achieved under mild conditions by developing a novel and simple sol-gel process occurring at the interface of an organic solvent and ice.
Journal ArticleDOI
Robust Co-catalytic Performance of Nanodiamonds Loaded on WO3 for the Decomposition of Volatile Organic Compounds under Visible Light
TL;DR: In this paper, nanodiamond (ND) was combined with WO3 (as an alternative co-catalyst for Pt) and applied for the degradation of volatile organic compounds under visible light.
Journal ArticleDOI
Role of Interparticle Charge Transfers in Agglomerated Photocatalyst Nanoparticles: Demonstration in Aqueous Suspension of Dye-Sensitized TiO2.
TL;DR: The interparticle charge transfer within the agglomerates of TiO2 nanoparticles in slurries markedly enhanced the dye-sensitized production of H2 under visible light by purposely decoupling the light absorbing part of Dye/TiO2 from the active catalytic center of Pt/Ti O2.
Journal ArticleDOI
Fabrication of Superior α-Fe2O3 Nanorod Photoanodes through ex-situ Sn-doping for Solar Water Splitting
Alagappan Annamalai,Pravin S. Shinde,Tae Hwa Jeon,Hyun Hwi Lee,Hyun-Gyu Kim,Wonyong Choi,Jum Suk Jang +6 more
TL;DR: In this article, both in-and ex-situ Sn-doped 1D hematite photoanodes have been demonstrated for photovoltaics and photoelectrochemical (PEC) systems; performance enhancements arise from both dopant incorporation and 1D nanostructures.
