CuO Nanoparticles/Ti3C2Tx MXene Hybrid Nanocomposites for Detection of Toluene Gas
Angga Hermawan,Biao Zhang,Biao Zhang,Ardiansyah Taufik,Yusuke Asakura,Takuya Hasegawa,Jianfeng Zhu,Shi Pei,Shu Yin +8 more
TL;DR: Toluene is one of the harmful volatile organic compounds (VOCs) for both human health and environments as mentioned in this paper, thus, to prevent the hazardous effect of toluene, fast detection at an early stage is needed.
Journal ArticleDOI
SnO-SnO2 modified two-dimensional MXene Ti3C2Tx for acetone gas sensor working at room temperature
Zijing Wang,Fen Wang,Angga Hermawan,Yusuke Asakura,Takuya Hasegawa,Hiromu Kumagai,Hideki Kato,Masato Kakihana,Masato Kakihana,Jianfeng Zhu,Shu Yin +10 more
TL;DR: In this article, a nanocomposite combining SnO-SnO2 (p-n junction) and Ti3C2Tx MXene was successfully synthesized by a one-step hydrothermal method.
Journal ArticleDOI
Carbon vacancies and hydroxyls in graphitic carbon nitride: Promoted photocatalytic NO removal activity and mechanism
Zhanyong Gu,Zhitao Cui,Zijing Wang,Ken Sinkou Qin,Yusuke Asakura,Takuya Hasegawa,Satoshi Tsukuda,Kenta Hongo,Ryo Maezono,Shu Yin +9 more
TL;DR: In this article, the carbon vacancies and hydroxyls co-modified carbon nanosheets were successfully prepared using a green hydrothermal method to achieve a 2.2 times higher photocatalytic NO removal performance than that of pristine CN.
Journal ArticleDOI
Bluish-White Luminescence in Rare-Earth-Free Vanadate Garnet Phosphors: Structural Characterization of LiCa3MV3O12 (M = Zn and Mg).
TL;DR: This study successfully discovered bluish-white emitting, garnet structure-based LiCa3MV3O12 (M = Zn and Mg) phosphors with a high quantum efficiency, and the detailed crystal structure was refined by the Rietveld analysis technique.
Journal ArticleDOI
