Journal ArticleDOI
On the electronic structure and hydrogen evolution reaction activity of platinum group metal-based high-entropy-alloy nanoparticles
Dongshuang Wu,Kohei Kusada,Tomokazu Yamamoto,Takaaki Toriyama,Syo Matsumura,Ibrahima Gueye,Okkyun Seo,Jaemyung Kim,Satoshi Hiroi,Osami Sakata,Shogo Kawaguchi,Yoshiki Kubota,Hiroshi Kitagawa +12 more
TL;DR: The synthesis of high-entropy-alloy (HEA) nanoparticles (NPs) consisting of five platinum group metals (Ru, Rh, Pd, Ir and Pt) through a facile one-pot polyol process is reported and the electronic structure of HEA NPs is investigated using hard X-ray photoelectron spectroscopy, which shows a broad valence band spectrum without any obvious peaks.
Journal ArticleDOI
Noble-Metal High-Entropy-Alloy Nanoparticles: Atomic-Level Insight into the Electronic Structure.
Dongshuang Wu,Kohei Kusada,Yusuke Nanba,Michihisa Koyama,Tomokazu Yamamoto,Takaaki Toriyama,Syo Matsumura,Okkyun Seo,Ibrahima Gueye,Jaemyung Kim,Loku Singgapulige Rosantha Kumara,Osami Sakata,Shogo Kawaguchi,Yoshiki Kubota,Hiroshi Kitagawa +14 more
TL;DR: The compositional space of high-entropy-alloy nanoparticles (HEA NPs) significantly expands the diversity of the materials library, which requires knowledge of the local electronic structure at an atomic level as mentioned in this paper .
Journal ArticleDOI
Chemistry of surface nanostructures in lead precursor-rich PbZr0.52Ti0.48O3 sol–gel films
TL;DR: In this paper, the chemistry of the nanostructured phase at the surface of lead zirconium titanate PbZr0.52Ti0.48O3 (PZT) films synthesized by sol-gel method was studied.
