Description

Synthese von Nanomaterialien auf Pt-Basis by Yangping Zhang Estimated delivery 3-12 business days Format Paperback Condition Brand New Description Als eine der wichtigsten Komponenten von Brennstoffzellen ist das Edelmetall Pt ein hocheffizienter Elektrokatalysator, der einen großen Einfluss auf anodische Reaktionen in Brennstoffzellen hat. Aufgrund der geringen natürlichen Reserven und des exorbitanten Preises des Edelmetalls Pt schränken diese Engpässe jedoch die praktische Entwicklung von Brennstoffzellen immer noch ein. Durch die Dotierung einiger kostengünstiger Metalle (z. B. Fe, Ni usw.) zur Herstellung von Katalysatoren auf Pt-Basis kann daher nicht nur die Nutzung von Edelmetallen verbessert, sondern auch die katalytische Leistung durch Legierungs- und Synergieeffekte gesteigert werden. Faktoren wie die oberflächliche Zusammensetzung und die Struktur der erhaltenen Katalysatoren sind für die katalytische Leistung von großer Bedeutung. Darunter befinden sich eindimensionale Materialien auf Pt-Basis mit relativ stabilem Aufbau und guter Elektronenleitfähigkeit, die das katalytische Verhalten erheblich verbessern könnten. In Anbetracht dessen würde eine effektive Entwicklung und Anpassung der Oberflächenstruktur von Pt-basierten Materialien, einschließlich der Netzwerk- oder Kern-Schale-Konstruktion, die katalytischen Eigenschaften aufgrund größerer oberflächlicher aktiver Bereiche und mehr reaktiver Stellen verbessern.

  1. Seller sent me the wrong book, but the book they sent sounded interesting enough for me to keep it. I still contacted the seller and communication was fast and professional. They apologized for sending me the wrong book and said I could return it for a refund. I told them that I liked the book they sent me and wanted to keep it. They were happy. Told them thank you and happy new year. People make mistakes, but the fact that this seller was quick and professional and apologized made a difference.

  2. The basket is perfectly what I ordered and as listed. It came in the factory packaging and was perfect upon delivery. Thank you postal service lol. The delivery took way longer than listed though, it was listed to come in a week from purchase, but took a whole month. I had some concerns at first, but communication with the company was top notch and they were very professional and answered most of my questions satisfyingly. Just prepare for a longer wait than listed, but I got what I bought lol.

  3. The two new out-of-print books I ordered were exactly as described and shipped promptly. I did ask the seller's support person (an AI chatbot, I think) to be sure to package the items carefully, and "he" said that he'd make that request of the shipping department. I knew this was hooey, and as I expected, the books were shipped in nothing but a padded paper mailer, no other protection. I got lucky, no damage, but don't bother making special requests of this seller.
