TLDR
In this paper, a review summarizes the results reported in the literature on the water gas shift (WGS) over gold-containing catalysts, focusing on the influence of the preparation method and the nature of the support on the gold dispersion and WGS activity.Abstract:
This review summarizes the results reported in the literature on the water gas shift (WGS) over goldcontaining catalysts. Attention is focused on the influence of the preparation method and the nature of the support on the gold dispersion and WGS activity. Special emphasis is paid to the enhanced reducibility of the metal oxide support in the presence of gold. Some aspects of the reaction mechanism of the WGS are discussed.read more

Current status of hydrogen production techniques by steam reforming of ethanol : A review
TL;DR: In this paper, the current state of the steam reforming process of ethanol, examines different catalysts, and makes a comparative analysis, and concludes that Co/ZnO, ZnO+Al2O3, Co/CeO2, Ni/La 2O3−Ni/La2O2−Al2E3, and Ni/E3−E2E2−E3 performed the best in terms of steam reforming of ethanol.

Plant-mediated synthesis of silver and gold nanoparticles and their applications
Vineet Kumar,Sudesh Kumar Yadav +1 more
TL;DR: In this article, the use of plants for synthesis of nanoparticles could be advantageous over other environmentally benign biological processes as this eliminates the elaborate process of maintaining cell cultures and can also be suitably scaled up for large-scale synthesis for nanoparticles.

Lingyan Wang,Jin Luo,Quan Fan,Masatsugu Suzuki,Itsuko S. Suzuki,Mark H. Engelhard,Yuehe Lin,Nam Kyu Kim,Jian Q. Wang,Chuan-Jian Zhong +9 more
TL;DR: Findings of an investigation of the synthesis and assembly of core-shell nanoparticles with high monodispersity are described, revealing a decrease in magnetization and blocking temperature and an increase in coercivity for Fe(3)O(4)@Au, reflecting the decreased coupling of the magnetic moments.

Onset of Catalytic Activity of Gold Clusters on Titania with the Appearance of Nonmetallic Properties
Mika Valden,X. Lai,D. W. Goodman +2 more
TL;DR: Results suggest that supported clusters, in general, may have unusual catalytic properties as one dimension of the cluster becomes smaller than three atomic spacings.

Size- and support-dependency in the catalysis of gold
TL;DR: In this article, the adsorption properties and reactivities of gold are summarized in terms of their size dependency from bulk to fine particles, clusters and atoms, and the catalytic performances of gold markedly depend on dispersion, supports, and preparation methods.

Gold catalysts prepared by coprecipitation for low-temperature oxidation of hydrogen and of carbon monoxide
TL;DR: In this paper, gold catalysts were prepared by coprecipitation from an aqueous solution of HAuCl4 and the nitrates of various transition metals, including Auα-Fe2O3, AuCo3O4, and AuNiO.

Low-Temperature Oxidation of CO over Gold Supported on TiO2, α-Fe2O3, and Co3O4
TL;DR: In this paper, the authors proposed a mechanism in which CO adsorbed on gold particles migrates toward the perimeter on support oxides and there it reacts with oxygen to form bidentate carbonate species.

The Water-Gas Shift Reaction
TL;DR: The water-gas shift is a reversible exothermic chemical reaction, usually assisted by a catalyst, and is the' reaction of steam with carbon monoxide to produce carbon dioxide and hydrogen gas as mentioned in this paper.
