Description

Sintesi di nanomateriali a base di Pt by Yangping Zhang Estimated delivery 3-12 business days Format Paperback Condition Brand New Description Essendo uno dei componenti importanti delle celle a combustibile, il metallo prezioso Pt è un elettrocatalizzatore altamente efficiente, che ha un grande effetto sulle reazioni anodiche nelle celle a combustibile. Tuttavia, a causa delle scarse riserve naturali e del prezzo esorbitante del metallo nobile Pt, questi ostacoli limitano ancora lo sviluppo pratico delle celle a combustibile. Pertanto, il drogaggio di alcuni metalli economici (come Fe, Ni, ecc.) per formare catalizzatori a base di Pt, non solo può migliorare l'utilizzo dei metalli preziosi, ma anche aumentare le prestazioni catalitiche grazie agli effetti di lega e sinergici. Fattori come la composizione superficiale e la struttura dei catalizzatori ottenuti sono molto importanti per le prestazioni catalitiche. Tra questi, i materiali monodimensionali a base di Pt, con una struttura relativamente stabile e una buona conducibilità elettronica, potrebbero migliorare significativamente i comportamenti catalitici. Alla luce di ciò, ingegnerizzare e personalizzare efficacemente la struttura superficiale dei catalizzatori a base di Pt, compresa la costruzione a rete o a guscio, migliorerebbe le proprietà catalitiche grazie ad aree attive superficiali più ampie e a un maggior numero di siti reattivi.

  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.
