Enhanced Photoelectrochemical Water-Splitting through Application of Layer by Layer (LBL) and Hydrothermal (HT) Methods in TiO<sub>2</sub> and -Fe<sub>2</sub>O<sub>3</sub> Hierarchical Structures
Aryan Azad, Sun Jae Kim
Korean J. Met. Mater. 2022;60(7):517-522.   Published online 2022 Jun 3
DOI: https://doi.org/10.3365/KJMM.2022.60.7.517

Abstract
Improving solar energy conversion efficiency and reducing energy loss have become critical issues in recent decades. Photoelectrochemical (PEC) water splitting provides an ideal method for solar energy harvesting and is a key factor in decreasing the use of fossil fuels. Thus, it is extremely important to identify cost-effective, highly active,..... More

                        
A Study on Sebum Hardening Effect of ZnO Powder
Sebum경화 기능형 ZnO powder 특성 연구
Yong Min Jeon, Jin Gu Kwon, Si Hong Ryu, Yeong Cheol Lee, Seong Eui Lee
전용민, 권진구, 유시홍, 이영철, 이성의
Korean J. Met. Mater. 2021;59(3):195-200.   Published online 2021 Feb 19
DOI: https://doi.org/10.3365/KJMM.2021.59.3.195

Abstract
Zinc oxide is transparent inorganic UV absorber and widely used as a sunscreen. But sunscreen on the skin is easily erased by sebum, so zinc oxide with a sebum curing function was studied. In this study, a zinc oxide powder was prepared using zinc chloride and sodium hydroxide via a..... More

                        
Improved Ultraviolet Photoresponse Properties of ZnO Nanorods Grown by Using Hydrothermal Method Applied Rotating Precursor Solution
Dongwan Kim, Jae-Young Leem
Korean J. Met. Mater. 2021;59(3):187-194.   Published online 2021 Feb 19
DOI: https://doi.org/10.3365/KJMM.2021.59.3.187

Abstract
We grew ZnO nanorods (NRs) using a hydrothermal method while rotating the precursor solution, and report the effect of rotation on surface modification, and the optical and ultraviolet (UV) photoresponse properties of the resulting ZnO nanorods. The ZnO NRs grown in the rotating precursor solution at 100 rpm had the..... More

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

Abstract
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
