Effects of fluorination and thermal shock on the photocatalytic activity of Bi2O3 nanopowders
Bouzıanı, Asmae; Park, Jongee; Öztürk, Abdullah (2021-10-05)
© 2021 Elsevier B.V.Fluorinated Bi2O3 (F-Bi2O3) nanopowder was prepared via fluorination followed by thermal shock of α-Bi2O3 nanopowder. The XRD, FTIR, SEM, and DRS characterization techniques were employed to investigate...
Enhanced methylene blue removal efficiency of TiO2 embedded porous glass
Ertus, E. Burak; Vakifahmetoglu, Cekdar; Öztürk, Abdullah (Elsevier BV, 2021-02-01)
A porous glass (PG) embedded with titanium dioxide (TiO2) was produced via impregnation of the PG with Titanium (IV) Isopropoxide solution followed by crystallization. N-2 sorption analyses revealed that the specific surfa...
Synthesis of alpha-Fe2O3/TiO2 heterogeneous composites by the sol-gel process and their photocatalytic activity
Bouziani, Asmae; PARK, JONGEE; Öztürk, Abdullah (Elsevier BV, 2020-09-01)
alpha-Fe2O3/TiO2 heterogeneous composites were synthesized by the sol-gel process to increase the photocatalytic activity of TiO2. The structural, morphological, and optical characteristics of the composites were determine...
Preparation and photocatalytic activity of g-C3N4/TiO2 heterojunctions under solar light illumination
Gundogmus, Pelin; PARK, JONGEE; Öztürk, Abdullah (Elsevier BV, 2020-09-01)
The solar light sensitive g-C3N4/TiO2 heterojunction photocatalysts containing 20, 50, 80, and 90 wt% graphitic carbon nitride (g-C3N4) were prepared by growing Titania (TiO2) nanoparticles on the surfaces of g-C3N4 partic...
Production and properties of phase separated porous glass
Ertus, E. Burak; Vakifahmetoglu, Cekdar; Öztürk, Abdullah (Elsevier BV, 2020-03-01)
A sodium borosilicate glass (SBG) was produced by conventional melt-quenching. As cast glass was heat treated to induce phase separation (SBG-HT), followed by acid leaching with HCl to dissolve one of the separated phases;...

Erdogan, Nursev; Bouziani, Asmae; PARK, JONGEE; Micusik, Matej; Kim, Soo Young; Majkova, Eva; Omastova, Maria; Öztürk, Abdullah (Elsevier BV, 2019-05-15)
TiO2 nanoparticles of the single anatase phase, binary anatase-brookite phases, and ternary anatase-brookite-rutile phases were synthesized using an HNO3-catalyzed hydrothermal process. The types and amounts of phases vari...
Alkaline Hydrothermal Synthesis, Characterization, and Photocatalytic Activity of TiO2 Nanostructures: The Effect of Initial TiO2 Phase
Erdogan, Nursev; PARK, JONGEE; Choi, Woohyuk; Kim, Soo Young; Öztürk, Abdullah (American Scientific Publishers, 2019-03-01)
One-dimensional (1D) titanate nanostructures were synthesized by hydrothermal route, using commercially available TiO2 (P25) and anatase powders as precursor materials and strong NaOH solution as catalyzer. The prepared ti...
Production of Photocatalytically Active TiO2 – P2O5 Glasses by the Sol-gel Process
Öztürk, Yiğit Cansın; Bouzıanı, Asmae; Efe, Mert; Park, Jongee; Kalem, Volkan; Öztürk, Abdullah (null; 2018-12-25)
Bulk TiO2-P2O5 glasses containing various amounts of TiO2 were successfully prepared by the sol-gel process followed by calcination at various temperatures. Influence of processing parameters on the formation of homogeneou...
