A simple hydrothermal preparation of TiO2 nanomaterials using concentrated hydrochloric acid

Morphological effect of TiO2 catalysts on photocatalytic degradation of methylene blue

“…Titanium dioxide nanostructures were prepared using concentrated HCl as a morphology controlling agent [11]. In a simple process, a desired volume of HCl (38%, Junsei) was drop-wise added into 15 ml of titanium n-butoxide (TBO, Ti(OBu) 4 , 98%, Acros) in a 100 ml Teflon-line stainless steel autoclave.…”

“…In addition, the structure, morphology and dimension of TiO 2 were characterized by transmission electron microscopy (TEM, Hitachi H-8100, Japan) and field-emission scanning electron microscopy (FE-SEM, JEOL, JSM-600F, Japan). Except part of HR-TEM images, all the characterization data were reported previously [11].…”

“…In our previous report [11], we introduced a simple hydrothermal preparation of TiO 2 materials using concentrated hydrochloric acid and easily tuned the morphology and structural property of the TiO 2 nanostructure by controlling the concentrated hydrochloric acid volumes in a hydrothermal process. In the present work, the fabricated TiO 2 materials with different morphologies were employed in the photocatalytic degradation of MB and the morphological effect of TiO 2 on MB photocatalytic degradation was investigated.…”

Degradation of Rhodamine B Dye by TiO2Nanotubes Photocatalyst Synthesized via Alkaline Hydrothermal Method

“…The method employed in this study is an easy and economical approach as compared to the conventional methods. The morphologies of the TiO 2 nanostructure can be controlled by changing the concentration of alkaline solution, hydrothermal reaction temperature and time [15]. TiO 2 nanotubes structure was chosen to be synthesized in this study due to its excellence properties compared to the common nanoparticles in photodegradation of organic dyes [16].…”

Synthesis of hierarchical rose bridal bouquet- and humming-top-like TiO2 nanostructures and their shape-dependent degradation efficiency of dye

“…The design of hierarchical TiO 2 superstructure constituted of nanometer-scaled building subunits has been became an attractive trend and an actual artfulness in nanosciences and nanotechnology in recent times due to their novel and unique shape-dependent features sprung from different mono-morphological nanostructures [4][5][6][7][8][9][10]. The hierarchical architecture has been found to be one of the most important factors directly influencing on the photocatalytic activity of TiO 2 -based catalyst [4,6,10].…”
