Metal cation doping which replace Ti4+ in TiO2 with a small amount of metal cation can improve the TiO2 photocatalytic activity under visible light by adjusting its energy band structure, change the electron-hole recombination and interfacial electron transfer rate.
The structure of the films prepared through this way contained rutile and anatase, and the rutile was major.

In the case of 4H-SiC, most of the lamellae identified up to now come from a combination of Shockley and/or Frank faults which manifests either as 3C [2, 3, 6] or 8H polytype [3, 7, 8, 9] or, in some cases, even more complex polytype structures [9, 10, 11].
Formation mechanism In the Hägg notation, these structures are made of a twisted arrangement of one or more threefold (+++) and (---) 3C-like lamellae, noticed SF(m) in Fig. 3.
Assuming a simple 4H/6H/4H type II QW system and the band structure parameters listed in Table 1, we computed the fundamental transition energies of a 6H QW in a 4H matrix.
From a quantum well model, each optical signature was associated to a structure.

This layer had a finer structure, where needle-like crystals were agglomerated.
Also, the calcium silicate layer obtained in condition II had a more porous structure than that in condition I (See the Figs. 2-(b) and (a)).
It has been demonstrated that the porous structure in the silica gels can be related to the apatite nucleation [6-8].

These one-dimensional nanorods (1D) with width of 40-90 nm are closely arranged to form the sheaflike structures with lengths of 1-2 µm, which can be well demonstrated by TEM image of a sheaflike architecture (Fig.2e).
However, the crystal structure is very unstable under high energy electron beam.

Effective hydrogenation of p-chloronitrobenzene over iridium nanoparticles entrapped in aluminum oxy-hydroxide under mild conditions Guangyin Fan1,a*, Chun Zhang1,b 1 Chemical Synthesis and pollution control Key Laboratory of Sichuan Province, College of Chemistry and Chemical Engineering, China West Normal University, Nanchong 637009 afanguangyin@cwnu.edu.cn, chunzhang@163.com Keywords: Iridium catalyst, p-chloronitrobenzene; selective hydrogenation Abstract.
The aim of the research reported here was to find a way to yield chlorinated amines under mild conditions by preparing a Ir/AlO(OH) catalyst with abundant hydroxyl groups and structure water, and further investigated the acceleration effect of hydrogen bond between the hydroxyl groups on support surface and substrates that we have put forward before.
The shoulder at 1640 cm-1 is the feature of the bending mode of absorbed water.[8] These results showed that there large amount of hydroxyl groups and structure water in the catalyst of Ir/AlO(OH), however, only the weakened peaks at 3287, 1384 and 1640 cm-1 were observed over Ir/Al2O3.
Catalyst Ir/AlO(OH) has large amount of structure water and hydroxyl groups than that of catalyst Ir/Al2O3, it reasonable suggested that due to the presence of large amount of structure water, the intermediate p-CNSB was easily desorbed on the surface of the catalyst, thus a high yield of p-CNSB was obtained under identical conditions.

Desulfurization Effect of High-sulfur Weibei Coal Assisted by Microwave Irradiation and Ultrasonic Wave ZhiyuanYang1,a*,Wang Sitong1,b,Tan Chao1,c and Li yanhong1,d 1College of Chemistry and Chemical Engineering, Xi’an University of Science and Technology, Xi’an 710054, P.R.
Introduction In China, the major source of energy is coal which accounts for more than 70% in the energy structure.
The results proved microwave could strengthen the function of peraceticacidand have no influence on the structure of its organic matter.
Due to the function of swelling and cavitations of ultrasonic wave, the coal structure will become loose and the coal particle and pore size will expand.
Thus, oxidants can enter the macromolecular structure of coal more easily to react.
