Korean J. Met. Mater. 2024;62(3):190-203.   Published online 2024 Feb 28
DOI: https://doi.org/10.3365/KJMM.2024.62.3.190

To develop an eco-friendly titanium (Ti) production process, the calciothermic reduction of titanium dioxide (TiO2) was investigated. The mechanism involved in the reduction of TiO2 using calcium (Ca) was examined. The influence of a molten salt, calcium chloride (CaCl2), on the calciothermic reduction was investigated by conducting experiments at 1123..... More

Catalyst-Free Thermal Evaporation Synthesis of TiO<sub>2</sub> Nanostructures in Atmospheric Air
대기압의 공기 분위기에서 촉매를 사용하지 않는 열증발법을 이용하여 생성된 TiO2 나노구조
Geun-Hyoung Lee
Korean J. Met. Mater. 2020;58(5):353-356.   Published online 2020 Apr 14
DOI: https://doi.org/10.3365/KJMM.2020.58.5.353

TiO2 nanostructures were synthesized using a thermal evaporation method without a catalyst. TiO powders mixed with graphite powders were used as the source materials. The synthesis process was performed in air atmosphere at 1000 °C. When the mass ratio of TiO/graphite in the source material was 2:1, TiO2 nanowires and..... More

이소영, 박성훈, 손호상
Korean J. Met. Mater. 2019;57(3):146-153.   Published online 2019 Feb 8
DOI: https://doi.org/10.3365/KJMM.2019.57.3.146

This study on the chlorination of ilmenite ore was carried out using chlorine gas and coke as the chlorinating and reduction agents in a static bed reactor for the selective removal of iron. The effect of the amount of coke, the partial pressure of the chlorine gas and the reaction..... More

Synthesis and Characterization of ZnO/TiO<sub>2</sub> Photocatalyst Decorated with PbS QDs for the Degradation of Aniline Blue Solution
Jong-Ho Lee, Hong-Joo Ahn, Jeong-Il Youn, Young-Jig Kim, Su-Jeong Suh, Han-Jun Oh
Korean J. Met. Mater. 2018;56(12):900-909.   Published online 2018 Dec 5
DOI: https://doi.org/10.3365/KJMM.2018.56.12.900

A ZnO/TiO2 photocatalyst decorated with PbS quantum dots (QDs) was synthesized to achieve high photocatalytic efficiency for the decomposition of dye in aqueous media. A TiO2 porous layer, as a precursor photocatalyst, was fabricated using micro-arc oxidation, and exhibited irregular porous cells with anatase and rutile crystalline structures. Then, a..... More

Study of the Morphological, Structural and Photoelectrochemical Properties of TiO<sub>2</sub> Nanorods grown by Hydrothermal Method
수열합성법으로 성장시킨 TiO2 나노로드의 형태학적, 구조적, 광전기화학적 특성 연구
Hayoung Choi, Hyukhyun Ryu, Won-Jae Lee
최하영, 류혁현, 이원재
Korean J. Met. Mater. 2017;55(1):46-52.   Published online 2017 Jan 5
DOI: https://doi.org/10.3365/KJMM.2017.55.1.46

We investigated the effects of growth duration on the morphological, structural, and photoelectrochemical properties of TiO2 nanorods grown on a TiO2-buffered fluorine-doped tin oxide (FTO) substrate using the hydrothermal method. From the study, we found that the photoelectrochemical properties were mainly dependent on the nanorod length and (002) XRD peak..... More
