Iridium Single Atoms to Nanoparticles: Nurturing the Local Synergy with Cobalt‐Oxide Supported Palladium Nanoparticles for Oxygen Reduction Reaction
Autor: Dinesh Bhalothia, Che Yan, Nozomu Hiraoka, Hirofumi Ishii, Yen‑Fa Liao, Sheng Dai, Po‐Chun Chen, Tsan‐Yao Chen
Publikováno v: Advanced Science, Vol 11, Iss 33, Pp n/a-n/a (2024)
Abstract A ternary catalyst comprising Iridium (Ir) single‐atoms (SA)s decorated on the Co‐oxide supported palladium (Pd) nanoparticles (denoted as CPI‐SA) is developed in this work. The CPI‐SA with 1 wt.% of Ir exhibits unprecedented high ma

Robustness of superconductivity to external pressure in high-entropy-alloy-type metal telluride AgInSnPbBiTe5
Autor: Md. Riad Kasem, Yuki Nakahira, Hitoshi Yamaoka, Ryo Matsumoto, Aichi Yamashita, Hirofumi Ishii, Nozomu Hiraoka, Yoshihiko Takano, Yosuke Goto, Yoshikazu Mizuguchi
Publikováno v: Scientific Reports, Vol 12, Iss 1, Pp 1-9 (2022)
Abstract High-entropy-alloy (HEA) superconductors are a new class of disordered superconductors. However, commonality of superconducting characteristics of HEA materials is unclear. Here, we have investigated the crystal and electronic structure, and

Relation between Electronic Structure and Thermoelectric Properties of Heusler-Type Ru2VAl Compounds
Autor: Hidetoshi Miyazaki, Shin-ichi Kimura, Kensuke Onishi, Takehiko Hihara, Masato Yoshimura, Hirofumi Ishii, Masashi Mikami, Yoichi Nishino
Publikováno v: Crystals, Vol 12, Iss 10, p 1403 (2022)
We investigated Heusler-type Ru2VAl, a candidate material for next-generation thermoelectric conversion, by first-principle calculations of its thermoelectric conversion properties and direct experimental observations of its electronic structures, em

Atomically dispersed nickel as coke-resistant active sites for methane dry reforming
Autor: Mohcin Akri, Shu Zhao, Xiaoyu Li, Ketao Zang, Adam F. Lee, Mark A. Isaacs, Wei Xi, Yuvaraj Gangarajula, Jun Luo, Yujing Ren, Yi-Tao Cui, Lei Li, Yang Su, Xiaoli Pan, Wu Wen, Yang Pan, Karen Wilson, Lin Li, Botao Qiao, Hirofumi Ishii, Yen-Fa Liao, Aiqin Wang, Xiaodong Wang, Tao Zhang
Publikováno v: Nature Communications, Vol 10, Iss 1, Pp 1-10 (2019)
While dry reforming of methane, the reaction of CH4 and CO2 to create CO and H2, is a promising reaction for industry, coke buildup often deactivates catalysts and limits commercialization. Here, authors report single-atom nickel on Ce-doped hydroxya
