Journal ArticleDOI

Development of dye-sensitized solar cells based on visible-light-responsive TiO2 thin films with a unique columnar structure

Takashi Toyao, +8 more
- 01 Jan 2013 - 
TL;DR: In this article, a visible-light-responsive TiO2 thin film (Vis-TiO2), possessing a unique columnar structure oriented perpendicular to the substrate, has been prepared by using a radiofrequency magnetron sputtering deposition method.
Journal ArticleDOI

Factors determining surface oxygen vacancy formation energy in ternary spinel structure oxides with zinc.

Yoyo Hinuma, +8 more
- 27 Oct 2021 - 
TL;DR: The surface O vacancy formation energy (EOvac) is a critical quantity for catalyst performance because the surface of metal oxide catalysts often acts as a reaction site, for example, in the Mars-van Krevelen mechanism.
Journal ArticleDOI

Lean NOx Reduction by In-Situ-Formed NH3 under Periodic Lean/Rich Conditions over Rhodium-Loaded Al-Rich Beta Zeolites

Shunsaku Yasumura, +5 more
- 01 Oct 2021 - 
Journal ArticleDOI

Greener and facile synthesis of Cu/ZnO catalysts for CO2 hydrogenation to methanol by urea hydrolysis of acetates

Nat Phongprueksathat, +4 more
- 15 Apr 2021 - 
TL;DR: In this article, the Cu/ZnO-based catalysts derived from calcination of the washed and unwashed precursors show catalytic performance comparable to the commercial CZNO/Al2O3 catalyst in CO2 hydrogenation at 240-280 °C and 331 bar.
Journal ArticleDOI

Surface activation by electron scavenger metal nanorod adsorption on TiH2, TiC, TiN, and Ti2O3

Yoyo Hinuma, +7 more
- 12 Aug 2021 - 
TL;DR: In this paper, the authors investigated the possibility of the electron scavenger effect in hydrides, carbides, nitrides, oxides, and sulfides with group 3, 4, or 5 cations.
