Abstract

PtCu Alloy Nanodendrites

In article number 2400272, Geoffrey I. N. Waterhouse, Jing Xu, and co-workers present an aqueous visible-light-driven system with fluorescein as the exited state photosensitizer, which upon light irradiation reduces Pt⁴⁺ and Cu²⁺ salts to generate PtCu alloy nanodendrites, resulting in in situ catalyzing hydrogen production. The PtCu alloy nanodendrites are collected in pure and used as the electrocatalyst, which exhibits impressive bifunctional electrocatalytic activity for nitrogen oxidation to nitrate and nitrite/nitrate reduction to ammonia.

用于电催化氮转化反应的铂铜合金纳米树枝状化合物的可见光驱动合成（Adv. Sustainable Syst.）

PtCu 合金纳米树突在编号为 2400272 的文章中，Geoffrey I. N. Waterhouse、Jing Xu 及其合作者介绍了一种以荧光素为出射态光敏剂的水溶液可见光驱动系统，该系统在光照射下还原 Pt4+ 和 Cu2+ 盐生成 PtCu 合金纳米树突，从而原位催化制氢。收集纯净的 PtCu 合金纳米枝晶并将其用作电催化剂，该催化剂在氮氧化成硝酸盐和亚硝酸盐/硝酸盐还原成氨的过程中表现出令人印象深刻的双功能电催化活性。
