Improved Solar-Driven Photocatalytic Activity of Hybrid Graphene Quantum Dots/ZnO Nanowires: A Direct Z-Scheme Mechanism
Mahdi Ebrahimi,Morasae Samadi,Samira Yousefzadeh,Mojtaba Soltani,Alireza Rahimi,Tsu-Chin Chou,Li-Chyong Chen,Kuei-Hsien Chen,Alireza Z. Moshfegh +8 more
TL;DR: In this article, an electrochemical technique as a cost-effective and one-step approach was utilized to fabricate graphene quantum dots (GQDs) Different amounts of GQDs (0, 02, 04, 08, and 12 wt %) were decorated uniformly on the surface of anodized ZnO nanowires (NWs) forming GQD/ZnO NWs.

Plasmonic Ag@Ag3(PO4)1−x nanoparticle photosensitized ZnO nanorod-array photoanodes for water oxidation
Yan-Gu Lin,Yan-Gu Lin,Yu-Kuei Hsu,Ying-Chu Chen,Sheng-Bo Wang,Jeffrey T. Miller,Li-Chyong Chen,Kuei-Hsien Chen,Kuei-Hsien Chen +8 more
TL;DR: In this article, a high-activity model for photocatalytic nanosystem comprising an Ag core covered with an approximately 2 nm thick nanoshell of Ag3(PO4)1−x (Ag@Ag3( PO4) 1−x ) on the ZnO NRs that are visible-light-sensitive photofunctional electrodes with strong photooxidative capabilities to evolve O2 from water.

Growth of Single-Crystalline Wurtzite Aluminum Nitride Nanotips with a Self-Selective Apex Angle†
Shih Chen Shi,Chia-Fu Chen,Surojit Chattopadhyay,Zon Huang Lan,Kuei-Hsien Chen,Li-Chyong Chen +5 more
TL;DR: In this paper, a self-selective apex angle in aluminum nitride nanotip growth is proposed, where the thickness of the gold-catalyst layer plays a critical role in controlling the size of the tip; in addition, a catalyst-free growth mode has been observed, which results in lesser control over the nanoteip morphology.
Journal ArticleDOI
Pyrolyzed Cobalt Corrole as a Potential Non‐Precious Catalyst for Fuel Cells
Hsin-Chih Huang,Hsin-Chih Huang,Hsin-Chih Huang,Indrajit Shown,Sun-Tang Chang,Hsin-Cheng Hsu,He-Yun Du,Ming-Cheng Kuo,Ken-Tsung Wong,Sea-Fu Wang,Chen-Hao Wang,Li-Chyong Chen,Kuei-Hsien Chen +12 more
TL;DR: In this paper, a new carbon-black-supported pyrolyzed Co-corrole (py-Co-Corrole/C) catalyst of the oxygen reduction reaction (ORR) in a PEFC cathode is demonstrated to have high catalytic performance.
Journal ArticleDOI
Quantum confinement effect in diamond nanocrystals studied by X-Ray-absorption spectroscopy
Y. K. Chang,H. H. Hsieh,Way-Faung Pong,M.-H. Tsai,F. Z. Chien,P. K. Tseng,L. C. Chen,T. Y. Wang,Kuei-Hsien Chen,D. M. Bhusari,J. R. Yang,S. T. Lin +11 more
TL;DR: In this paper, the x-ray-absorption spectra of a series of nanodiamond thin films with grain diameters ranging from 3.5 nm to $5\ensuremath{\mu}\mathrm{m}$ at the C $K$-edge using the sample drain current mode at room temperature were measured.
