Nitrogen-plasma treated hafnium oxyhydroxide as an efficient acid-stable electrocatalyst for hydrogen evolution and oxidation reactions
Autor: Xiaofang Yang, Fang Zhao, Yao-Wen Yeh, Rachel S. Selinsky, Zhu Chen, Nan Yao, Christopher G. Tully, Yiguang Ju, Bruce E. Koel
Publikováno v: Nature Communications, Vol 10, Iss 1, Pp 1-8 (2019)
Renewable hydrogen technologies are promising for alternative energy, but are encumbered by the kinetics of electrochemical reactions in harsh conditions. Here, authors report nitrogen-modified hafnium oxyhydroxide for electrocatalysis of hydrogen ev

Stable synthesis of few-layered boron nitride nanotubes by anodic arc discharge
Autor: Yao-Wen Yeh, Yevgeny Raitses, Bruce E. Koel, Nan Yao
Publikováno v: Scientific Reports, Vol 7, Iss 1, Pp 1-7 (2017)
Abstract Boron nitride nanotubes (BNNTs) were successfully synthesized by a dc arc discharge using a boron-rich anode as synthesis feedstock in a nitrogen gas environment at near atmospheric pressure. The synthesis was achieved independent of the cat

Mechanistic Elucidations of Highly Dispersed Metalloporphyrin Metal‐Organic Framework Catalysts for CO 2 Electroreduction
Autor: Michael R. Smith, Clare B. Martin, Sonia Arumuganainar, Ari Gilman, Bruce E. Koel, Michele L. Sarazen
Publikováno v: Angewandte Chemie. 135
Immobilization of porphyrin complexes into crystalline metal-organic frameworks (MOFs) enables high exposure of porphyrin active sites for CO2 electroreduction. Herein, well-dispersed iron-porphyrin-based MOF (PCN-222(Fe)) on carbon-based electrodes
