The sorption of cationic dyes on hydrated tin(IV) oxide

Surface Technology, 1984
Abstract The sorption-desorption of methyl violet 6 B, phenosafranine and Janus red on freshly hydrated tin(IV) oxide, prepared under various conditions, was studied. Hydrated tin(IV) oxide (β form), prepared by the oxidation of tin metal with hot 35 wt.% HNO 3 , was subjected to chemical pretreatment with aqueous NaOH of various concentrations ...

Sulfonated polyether ether ketone and hydrated tin oxide proton conducting composites for direct methanol fuel cell applications

Journal of Power Sources, 2008
Abstract Composite membranes based on sulfonated polyether ether ketone (SPEEK) and hydrated tin oxide (SnO 2 · n H 2 O) were prepared and characterized. The formation of the composite substantially modified the properties of SPEEK in terms of durability and electrochemical performance.

The Texture and Heat Treatment of Hydrated Tin (IV) Oxides

1977
Various preparations of hydrated tin (IV) oxides are reported. These are classed as α- or β- stannic acids according to their stability in concentrated hydrochloric acid. Precipitation in the cold gives α- stannic acid, whilst preparations at high temper­ature result in β- stannic acid; the former being of smaller particles than those of the latter.

The effect of Sn(IV) on transformation of co-precipitated hydrated In(III) and Sn(IV) hydroxides to indium tin oxide (ITO) powder

Materials Letters, 2002
Multicomponent metal oxide (indium tin oxide, ITO) powders were prepared by the hydrolysis of their corresponding metal salts following co-precipitation technique. Indium tin oxide powders with relatively high content of tin were prepared by the treatment of aqueous NH4OH with the mixture of aqueous In(NO3)3 and SnCl4 solution (pH=8.4–8.7) at an ...

Tin Active Sites Confined in Zeolite Framework as a Promising Shape‐Selective Catalyst for Ethylene Oxide Hydration

Chemistry – A European Journal, 2023
AbstractShape‐selective stannosilicates have been post‐synthesized for the hydration of epoxide to diols. A simple acid treatment has been employed to remove extensively the interlayer double four ring units, converting the three‐dimensional (3D) UTL germanosilicate into a 2D layered IPC‐1P intermediate.

Heterogeneously Catalyzed Efficient Hydration of Alkynes to Ketones by Tin–Tungsten Mixed Oxides

Chemistry – A European Journal, 2010
AbstractThe Sn–W mixed oxide prepared by calcination of the Sn–W mixed hydroxide precursor with a Sn/W molar ratio of 2:1 at 800 °C (SnW2‐800) acts as an efficient heterogeneous catalyst for the hydration of alkynes. Structurally diverse terminal and internal alkynes, including aromatic, aliphatic, and double‐bond‐containing ones, can be converted into
