Photocatalytic H2 evolution under visible-light irradiation on modified TiO2 catalysts Huirong Liang1,2,a, Liejin Guo2,b 1Xi’an Shiyou University, Xi’an, China 2State Key Laboratory of Multiphase Flow in Power Engineering, Xi’an Jiaotong University, Xi’an, China ahrliang@mail.xjtu.edu.cn, blj-guo@mail.xjtu.edu.cn Keywords: hydrogen evolution, photocatalyst, titanium dioxide.
In addition, as a simple structure and excellent stability, TiO2 is also the best model material to study photochemical and photophysical properties of the catalysts.
The reference sample of TiO2 is prepared with butyl titanate, isopropyl alcohol and concentrated nitric acid as raw materials by the sol-gel method.
The identification and molecular structure of the materials are confirmed by the Raman spectra which are performed on the Jobin Yvon LabRAM HR Spectrometer using 514.5nm irradiation from an argon ion laser at 20 mW.

Introduction The production of copper from sulphide raw materials by pyrometallurgical processing leads to the production of impure copper anodes which can not meet the requirement for purity in the most applications fields, thus, copper must be electrorefined[1].
The conventional treatment has a number of disadvantages: (i) difficult materials handling, (ii) energy consumption, (iii) possibility of forming toxic arsine gas and (iv) loss of high value copper in a low value recycle product [3].

The 3D design models of machining parts which are received by process engineer are usually transformed into two dimensional (2D) engineering drawings, which are used for guiding machining by workers.
The model based definition can express multiple product information completely with the 3D model, which also contain the information of 2D engineering drawing.
The course of process is actually the evolution that workblank is machined into design model by removing the extra materials.
