Abstract

We present the preparation and electrochemical analysis of a novel type of positive regenerative fuel cell electrode based on commercially available Ti felts with a Pt/Ir catalyst. Anodic oxidation of the Ti felts leads to the formation of a TiO nanotube layer. The high specific surface area allows for a particularly efficient utilization of the noble metal catalyst. Its loading in the nanoporous system is controlled accurately and minimized systematically by atomic layer deposition. The electrochemical activity towards water splitting of both metals is investigated in acidic media by cyclic voltammetry and steady-state electrolysis for various catalyst loadings. An optimal oxygen evolution reaction is found for a catalyst loading of 76 μg cm resulting in a mass activity of 345 A g at =0.47 V, whereas the simultaneous presence of Pt at the surface is demonstrated by X-ray photoelectron spectroscopy and by the high activity observed for the hydrogen evolution reaction.

摘要

我们展示了一种基于带有Pt/Ir催化剂的市售钛毡的新型正再生燃料电池电极的制备及电化学分析。钛毡的阳极氧化导致形成TiO纳米管层。高比表面积使得贵金属催化剂能够得到特别有效的利用。通过原子层沉积精确控制其在纳米多孔体系中的负载量，并系统地将其降至最低。通过循环伏安法和稳态电解，在酸性介质中研究了两种金属对水分解的电化学活性，考察了不同催化剂负载量的情况。发现对于76 μg cm的催化剂负载量，析氧反应达到最佳，在 =0.47 V时质量活性为345 A g，而X射线光电子能谱以及析氢反应所观察到的高活性证明了表面同时存在Pt。
