Introduction The performance of nanostructured ZnO devices strongly depends on the electrical properties of the ZnO nanostructures as well as their surface chemistry.
Wettability is governed by both the chemical composition and the geometrical structure of solid surface [1].
Our previous study [4] reported that films with ordered ZnO pore structures can be used in nanostructured ZnO/ polymer solar cells to promote the photoconductivity by increasing ZnO–polymer heterojunction area and enhancing light trapping.
Nest-like pore structures with thick and continuous edges were obtained.

The absorption wavelength at 215 nm is the structure of Benzene, and the absorption wavelength at 215 nm is the structure of Naphthalene, while the absorption wavelength at 544.2 nm is the conjugated system of Benzene, Naphthalene and -N=N-.
Changing the reaction time, the pH of Reactive Red 2BF and the dosage of potassium ferrate on the activity of Reactive Red 2BF wastewater treatment process, potassium ferrate exhibited greater oxidation activity for the deterioration of organic dye which has complex structure.

Conversion of the polar cyano groups to carboxylic groups in the polyacrylonitrile fiber is the main purpose of hydrolysis. [4]Hydrolysis of the polyacrylonitrile fiber occurres on the fiber surface, so the inner structure of the fiber does not changed seriously and minimal damage to its strength.
According to the structure of the fiber, qualitative judgment the hydrolysis effect of the polyacrylonitrile can be achieved based on the number of carboxyl groups.
It can be seen from the Fig.3a, polyacrylonitrile fiber has smooth surface of ravines and compact structure.

The superporous structure could be prepared by using a gas blowing technique that could generate an interconnected pore structure to form open channels for fast water absorption by capillary force.
Surface and inner pore structures of dried SPH samples were observed by SEM.
The superporous structure could not be formed below pH=4 and above pH=5, while the hydrogel with good pore structure could be prepared from the pH values of 4.5 and 4.75.
Pore structures of SPHs.

Characterization using XRD and FTIR indicated that the ordered structure of MCM-41 could be synthesized by ultrasonic wave.
While based on the TEM image, the material has hexagonal or a honey-comb structure.

Interestingly PPY/TTX–100 showed uniform hollow structure.
Moreover, the surface morphology of PPY synthesized in the presence of TTX–100 (figure.6b) shows hollow tubular structure with differently oriented sizes and shapes.
It shows void like structure which may play a crucial role for ascertaining the potential of these materials for sensors applications.
