B. C. Dutt and S. N. Sen found that when nitric oxide is passed into a suspension of barium dioxide in water, barium nitrite, not nitrate, is formed. P. Sabatier and J. B. Senderens observed no change when nitric oxide is passed over Cuprous Oxide at 500°. H. A. Auden and G. J. Fowler observed that dry nitric oxide and Silver oxide, at ordinary temp., form silver and silver nitrate P. Sabatier and J. B. Senderens also obtained silver and silver nitrite by passing nitric oxide into water with silver oxide in suspension. C. F. Schonbein found gold oxide is reduced by moist nitric oxide, forming nitrous acid. P. Sabatier and J. B. Senderens found that titanium sesquioxide forms white titanic oxide when heated in an atm. of nitric oxide and that stannous oxide below 500° burns in an atm. of nitric oxide, forming stannic oxide. If nitric oxide be passed into water with lead dioxide in suspension, the water is coloured, and in about 3 hrs., lead nitrite and nitrate are formed, and later, rhombic crystals of a basic nitrite. B. C. Dutt and S. N. Sen said that the nitrate is formed by the action of the dioxide on the nitrite. Lead dioxide is reduced to lead oxide by nitric oxide at 315°, and H. A. Auden and G. J. Fowler found that the reaction begins at 15°, when a basic lead nitrite is... 

Mixed ethers result when alcohols and phenols are used with thoria at 390°—420° and esterification takes place when alcohol and acid interact at 350°-400°. Esterification10 is more complete in the presence of titanic oxide at 280°—300°. One molecule of acid is used with twelve molecules of alcohol, and in this way methyl, ethyl, propyl, butyl, and benzyl esters have been prepared from acetic, propionic and butyric acids.

Lithium titanate oxide Li4Ti50i2 has a crystalline structure which is isomorphic to that of the mineral MigAl204 (magnesium aluminum oxide) called spinel (central column in Figure 5.5). 

Exercise 5.4.- using Faraday s law (see section 2.3.2.2), calculate the theoretical mass capacity of lithium titanate oxide. 

Perovskite structures of rare earth titanate oxides are of considerable interest in recent years [63,64], Among different rare earth metals, lanthanum was the most investigated. In order to accommodate the excess oxygen, the replacement of divalent cations such as Ca or Sr in general perovskite materials by a tri-valent cation such as La " resulted in excess electrons and slabs of a distorted perovskite structure. With the highly donor-doped (110) perovskite, the separation of electrons and holes is more facile than other semiconductor materials because of a narrower depletion layer and a more drastic band bending. In this way the activity of the photocatalytic processes were improved. As obviously, to suppress the recombination of the generated electrons and holes is an important condition [63,64]. 

The absolute levels of the frontier x -MOs in fluorinated Zn" and Cu" phthalocyanines were experimentally determined using ultraviolet photoelectron spectroscopy (UPES) of the thin films deposited on different surfaces [8, 18, 37, 64]. As can bee seen from Fig. 4 the experimental HOMO and LUMO levels and their trends upon fluorination are in a good agreement with theoretical results. The LUMO level for perfluorinated phthalocyanine complexes is comparable with the energy level of Au (-5.1 V) and lower than for indium-titan oxide (ITO) (-4.8 eV)...
