Synthesis of Bi2O3/Ag3PO4 Composites and their Photocatalytic Activities under Visible Light Irradiation Uyi Sulaeman1,a, Estri Yunari1, Ponco Iswanto1, Shu Yin2, Tsugio Sato2 1 Department of Chemistry, Jenderal Soedirman University, Purwokerto, 53123, Indonesia 2 Institute of Multidisciplinary Research for Advanced Materials, Tohoku University, Sendai, 980-8577, Japan auyi_sulaeman@yahoo.com Keywords: Ag3PO4, Bi2O3, composite, photocatalyst, visible light Abstract.
For example, the novel heterojunction structures of Ag3PO4/TiO2 fabricated by covering the surface of Ag3PO4 with polycrystalline TiO2 using sol–gel method showed high photocatalytic activity for the removal of gaseous 2-propanol and in evolution of CO2 [4].
The crystal structure of Bi2O3/Ag3PO4 was characterized using XRD (x-ray diffractometer).
The values of band position indicated that pure Bi2O3 and Ag3PO4 have the nested band structure before contact, which seems to be detrimental to the separation of the photogenerated carriers [11].

In the experiment, considering PG contained branched chain structure, the grinding of the putty was improved, but the liquidity of the resin was hindered.
Analysis showed that, the liquidity of the resin was hindered by the branched chain structure of PG, while the liquidity of the resin was enhanced by the ether bond of DEG.
Analysis showed that, branched chain structure was contained in PG, relative to the equimolar amounts of DEG, the double bond distance of the unit length of molecular chain was shorter, density was higher, then crosslinking point increased when the resin was cured.
Analysis showed that, with the increase of dosage of PG, branched structure within the system increased, the grinding of the putty was improved, when PG achieved appropriate amount and continued to increase, the viscosity of the resin increased, the amount of filler reduced, the grinding of the putty lowered.

The results indicated that the samples possess a single spinel-type structure.
The crystal structure parameters are shown in Table 1.
Table 1 Crystal structure parameters of MAl2O4(M=Mg，Zn，Cu).
Whether the structure of spinel is normal or inverse depends on the octahedral site preference energy (OSPE) of transition metal ions and the rules of metal ions site occupancy in the spinel structure.

Each ladle had its specific chemistry originating from the same base melt.
Although, for alloy number 4, with only Nb added to the original chemistry, only the stress values are improved with no positive effect on the TMF-life.
Further, for the longest solidification time, the results implied that the effect of alloying gets diminished by the attained coarsening of the structure.
First, all specimens are mainly pearlitic and it is noted that the dendritic structure shown in the first column, is refined for the alloyed specimens compared to the un-alloyed sample 2.
Niobium on the other hand is expected to stabilize and refine the pearlite structure [8].

These reflections can be indexed based on the gold nanoparticles face centred cubic structure.
Therefore, these could be attributed to the presence of organic compounds (phenolics, flavonoids, terpenoids, etc.) embedded within the plant extract, were said to be responsible for the capped structure developed.

The essential signal for selecting a desalination technique is genuine energy usage, regardless of whether the power is in the high-grade structure, such as electricity, steam, or low-grade, such as low-temperature waste heat or renewable energy.
The structure of these isotherms retains much knowledge about the essence of the phase of adsorption.
It has been shown that surface properties such as surface chemistry and pore size distribution (PSD) of adsorbents play a significant role in the adsorption process hence the study is conducted.
The adsorbent pore size distribution (PSD) specifies the fraction of its structure which a molecule of given size and shape can access.

The integration of materials into fibers structure can be done in several ways.
But the easiest way of integrating new material into fibers structure is by dissolving desired materials into a polymeric solution.
It was concluded that the addition of ZnO particles would not significantly affect or disrupt the structure of resultant PVA nanofibers.
Thus ZnO particle can be conveniently and safely integrated into PVA nanofibers structure for any potential applications.

This implies that the crystalline structure within LFS-isolated starch is different from those of starches isolated with other steeping liquors, and further reveals that the lactic fermentation solution may alter the crystalline structure of starch during isolation [7].
Chen et al. [9] studied the effect of ball milling on crystalline structure of mung bean starch, the crystalline structure of mung bean starch was destroyed in the process of ball milling, and the crystals were changed from polycrystalline to a more disordered structure.

The polycrystalline anatase structure is mainly confirmed by the presence of (101), (004) and (200) diffraction peaks.
XRD analyses were also performed in order to evaluate the crystalline structure of TiO2-NNPs coated ceramic samples.
Regarding the ceramic samples coated with the TiO2-NNPs based layers, it can be observed that all of them present a highly pored surface structure in which the TiO2 nanoparticles tend to aggregate, forming clusters.
