A Visible Light-Induced Fe3O4/ZnO-Cu Nanocomposite and its Photocatalytic Activities for Rhodamine B Photodegradation Yuly Pujiartia*, Suyantab, and Eko Sri Kunartic Department of Chemistry, Universitas Gadjah Mada, Sekip Utara, Yogyakarta 55281 Indonesia ayulypujiarti94@mail.ugm.ac.id, bsuyanta_mipa@ugm.ac.id, ceko_kunarti@ugm.ac.id Keywords: Fe3O4/ZnO-Cu nanocomposite, Rhodamine B photodegradation, visible light.
Meanwhile, the diffraction patterns of ZnO with the hexagonal structures could be found at 2θ 31.77°; 34.42°; 36.25°; 47.53°; 56.60°; and 62.86° which is attributed to the JCPDS ZnO #00-036-1451 with facet planes of (100), (002), (101), (102), (110), and (103) [19], respectively.
Also, the peaks except for ZnO and Fe3O4 compound (CuO and Cu2O) were not observed, suggesting that the substitution of Cu in ZnO lattice was not altering the wurtzite structure of ZnO.
The increase of band gap energy for Fe3O4/ZnO-Cu 3% might be due to the Burstein Moss effect which explains the addition of free hole charge carrier of metals into ZnO lattice structure.

As the plasticizing activity and, consequently, the mechanism of action of PFM are determined by their nature, composition and structure, in the course of the research the modifiers with various adsorption-active groups were used: S-3 liquefier and LST, containing sulfogroups SO3- as hydrophilic groups, and SP SB-3, containing hydroxyl groups and their mixtures.
To determine the composition and structure of oligomeric molecules the liquid and gas-liquid chromatography, ultraviolet and infrared spectroscopy, NMR-spectroscopy, conductometry and potentiometry were used.
The surface tension at the solution-air boundary allows implicitly evaluating the extent of additional air entrainment to cement mix, which within reasonable and regulable limits improves the pore space structure, which in its turn increases the freeze-thaw resistance of concrete [15].
