Effects of solution concentration and capping agents on the properties of potassium titanyl phosphate noparticles synthesized using a co-precipitation method

Synthesis of γ-alumina (Al2O3) nanoparticles and their potential for use as an adsorbent in the removal of methylene blue dye from industrial wastewater

“…18,[22][23][24] Precipitation is an easy, simple and cost-effective method for the synthesis of nanoparticles and their composites, especially when the solvent used can be recycled. 25 The surface properties of the materials being produced can be inuenced by controlling the concentration, the solvent, and the calcination step depending on the needs of a given application. There are many nanomaterials now commercially available so that adsorbents can be tailored for a specic requirement.…”

The Effect of Polyvinyl Alcohol Concentration on the Growth Kinetics of KTiOPO4 Nanoparticles Synthesized by the Co-precipitation Method

“…The FE-SEM images of KTP nanoparticles synthesized without and with using different mole ratios of capping agent are shown in Figure 3. Poly dispersity index (PDI) [18] was calculated via Image-J software. PDI and particle size of obtained KTP powders with different mole ratios of polyvinyl alcohol are given in Table 1.…”

“…Therefore, precise control of the size and shape of nanocrystals, results in desired chemical and physical properties. Pechini [13], Sol-gel [14], mechanochemical mixing [15], combustion [16], co-precipitation [17,18], and hydrothermal [19] methods have been used to prepare KTP nanostructures. Mechano chemical, sol-gel, and pechini are primitive methods for the synthesis of KTP nanoparticles.…”

High Specific Surface Area γ-Al2O3 Nanoparticles Synthesized by Facile and Low-cost Co-precipitation Method

“…γ-alumina and α-alumina are the only types of alumina that are commercially produced until now 4,[19][20] . Also, nano alumina can be synthesized by various routes, such as hydrothermal 21 , mechanical milling 22 , co-precipitation [23][24] , vapor phase reaction 25 , arc plasma 26 , sol-gel 20 , and homogeneous precipitation 27 .The co-precipitation method (CPM) is an easy, simple, and cost-effective synthesis method, which provides the ability to control the particle crystalline size, morphology, and numerous prospects of the NPs to customize the particle surface and properties by determining the relative rates of nucleation and growth during the synthesis process, especially when removing the solvent [28][29][30] . Also, different precipitating agents like sodium carbonate, sodium bicarbonate, ammonium carbonate, ammonium bicarbonate 23 , ammonium hydroxide 31 , and hexamethylene tetramine 32 , and also different synthesis parameters have been used to synthesize high specific surface area (SSA) Al2O3 nano-powders.…”
