The results were further confirmed using SEM image in which catalyst activation under nitrogen flow has produced abundance microcrystal structure than under air condition.
The structure and morphology of the catalyst were characterized by using scanning electron microscopy (SEM;Carl Zeiss EVO MA 10) at the accelerating voltage of 15kv.
From the Scherrer equation, the average crystal size of the catalyst is between 23 to 31nm indicates that the catalyst was in the nanocrystals structure.

Chemical structure of PLA, PBAT, and their blends was analysed using a Fourier-transform infrared spectrometer Nicolet 6700 (Thermo Fischer Scientific).

In this work it was carried out the synthesis of Bi2InTaO7 pyrochlore-type structure compound by the sol-gel method.
By X-Ray powder diffraction the sol-gel compound calcined at 600°C showed the pyrochlore-type structure phase and by scanning electron microscopy its morphology revealed the presence of particles with size lower than 1 micron.
Introduction Pyrochlore-type structure compounds prepared by solid state reaction have been showed to be excellent photocatalyst for water splitting reaction and for the organic pollutants degradation [1-7].
These compounds are showing the pyrochlore-type structure.

Nano-ceramic materials All materials were synthesized through wet chemistry processes obtaining ZnO powders in a large variety of nanoforms shaped like nano-sheets (NS), bisphenoidal nanoaggregates (BP), nano-flowers (NF), short and long acicular nanocrystals (SN and LN), nano-spindles (not considered in this work) and flower-like structures (FL).
SEM micrographs of ZnO nanocrystals: short needles (a), long needles (b), flower-like structures (c).
However, the fine structure is given by nanoparticles of about 60-70 nm sized.
The same situation is offered by the bisphenoids which z axis is about 10 µm and the fine structure is constituted by nanoparticles only slightly lower than those of the NS powders, while NF sample showed grains about 30 nm in size in a flower structure which diameter is about 1 µm.
