Serb. Chem. Soc. VL - 88 IS - 3 SE - Materials DO - 10.2298/JSC221102090R UR - https://shd-pub.org.rs/index.php/JSCS/article/view/12126 SP - 313–325 AB - <p>A biphasic [Mn(dipya)(H<sub>2</sub>O)<sub>4</sub>](tpht)/{[Zn(dipya)(tpht)]·H<sub>2</sub>O}<sub>n</sub> com­plex material, <strong>I</strong> (dipya = 2,2’-dipyridylamine, tpht2– = dianion of terephthalatic acid) was synthesized by ligand exchange reaction and characterized by XRPD and FTIR spectroscopy. A ZnO/ZnMn<sub>2</sub>O<sub>4</sub> composite, <strong>II</strong>, has been prepared <em>via</em> thermal decomposition of <strong>I</strong> in an air atmosphere at 450 °C. XRPD, FTIR and FESEM analyses of <strong>II </strong>revealed the simultaneous presence of spherical nano­particles of wurtzite ZnO and elongated nanoparticles of spinel ZnMn<sub>2</sub>O<sub>4</sub>. The specific surface area of <strong>II</strong> was determined by the BET method, whereas the volume and average size of the mesopores were calculated in accordance with the BJH method. The measurements of the mean size, polydispersity index and zeta potential showed colloidal instability of <strong>II</strong>. Two band gap values of 2.4 and 3.3 eV were determined using UV–Vis diffuse reflectance spectroscopy, while the measurements of photoluminescence revealed that <strong>II </strong>is active in the blue region of the visible spectrum. Testing of composite <strong>II</strong> as a pigmentary material showed that it can be used for the colouring of a ceramic glaze.</p> ER -
