The cerium dioxide films were prepared with cerium foils as raw materials by anodization in Na2C2O4-NH3∙H2O-H2O-(CH2OH)2 electrolyte.
If the porous cerium dioxide film is prepared with cerium foils as raw materials, we may solve the above problems.
In this paper, The cerium dioxide films were prepared with cerium foils as raw materials by anodization in Na2C2O4-NH3∙H2O-H2O-(CH2OH)2 electrolyte.

Laser beam can be used to cut or perforate in many kinds of materials, weld and harden metal material, and deal with alloying, including coating, stripping, marking, cladding etc [1].
It can simulate the laser cladding processing planning based on industrial robots (Laser cladding means that by adding the cladding material in the substrate surface and using high-energy density laser beam to heat it, thin cladding material and substrate surface are melted and froze rapidly to form cladding materials in the substrate surface.)

Briefly, the starting materials 8%mol MgO was dissolved in 0.5 mol/L ZrOCl2.8H2O solutions to form mixed solution.
With the temperature increased to 800°C and 950°C, diffraction pattern of the tetragonal phase and monoclinic phase exist in the composites, As the temperature further increased to 1100°C, all of the materials mainly exhibit monoclinic phase.
The partially stabilized zirconia (MgO-PSZ) is a well-known material in modern ceramic.

However, traditional adsorption usually uses expensive activated carbon or active carbon fiber, it is very necessary to seek adsorption materials which are abundant, effective and cheap.
There are many reports about adsorption of heavy metal ions with biomass material [1-5].
