Journal ArticleDOI
Preparation and ion-exchange properties of a new phase of the crystalline titanium phosphate, Ti(HPO4)2·2H2O
TL;DR: In this article, a new inorganic ion-exchanger with the formula Ti(HPO4)2·2H2O and its ion exchange properties towards sodium and strontium ions was reported and discussed.
Journal ArticleDOI
Catalytic activity of zirconium phosphate and some derived phases in the dehydration of alcohols and isomerization of butenes
TL;DR: The catalytic activity of α-Zr(HPO 4 ) 2 · H 2 O prepared by different methods and of phases derived from it by heating between 200 and 1100 °C or by ion exchange with Na +, Cs +, or Ag +, has been investigated by means of different acid-catalyzed test reactions, namely, isopropanol, 1- or 2-butanol dehydration, and 1-butene isomerization.
Journal ArticleDOI
X-ray photoelectron spectroscopic evidence of interlayer complex formation between Co(II) and N-heterocycles in α-Zr(hpo4)2 · H2O
TL;DR: In this paper, the shape of the Co2 p photoelectron peak indicates that high-spin N-coordinated Co(II) is present mixed with O-coordinate Co(I) in zirconium phosphate-phen composite.
Journal ArticleDOI
The use of thermoanalytical techniques in the characterization of ancient mortars
TL;DR: In this article, a comparative investigation on calcitic and dolomitic mortars from two different Italian buildings of the 11th and 14th centuries has been performed using different techniques (TG/DTA, XRD and chemical analysis).
Journal ArticleDOI
Characterisation and electronic properties of some inorganic ion exchangers of the zirconium phosphate type containig transition-metal ions
TL;DR: A series of transition-metal-ion forms of crystalline zirconium phosphate of general formula ZrM(PO4)2·4H2O (M = ZnII, CuII, NiII, CoII, and MnII) has been characterised as mentioned in this paper.
