Platinized Titanium Anode

Platinum possesses remarkable attributes such as excellent electrical conductivity, outstanding resistance against corrosion, as well as high temperatures and voltage levels. Moreover, its capacity to facilitate a variety of chemical reactions positions it as an exceptional choice for electrochemical applications. Nevertheless, the steep expense of platinum makes the production of bulk platinum anodes impractical for many manufacturers. To address this, alternatives have emerged that involve applying a fine layer of platinum over a substrate composed of a more affordable corrosion-resistant material.

A prevalent example of these formulations is based on titanium substrates, though options made from niobium, tantalum, carbon, and various alloys are also available. These platinized anodes are increasingly preferred due to their durability and functionality at high voltages, finding applications across diverse fields, including cathodic protection, electroplating, and chemical sensing.

One of the most significant recent applications has been in the domain of Proton Exchange Membrane (PEM) electrolysis, wherein porous titanium meshes or felts are coated with platinum to serve as both a catalyst and a gas diffusion layer (GDL) for hydrogen generation. This has spurred considerable investment aimed at optimizing the production process, ensuring it remains economically viable. However, the challenge arises from the thin nature of the platinum layer combined with the porous design, which complicates the quantification of the platinum amount on the substrate, hindering manufacturers in assessing their production efficiency.

X-Ray Fluorescence presents a viable solution to this issue. Bowman XRFs can accurately quantify platinized coatings down to a few nanometers due to their impressive detection sensitivity and minimal noise levels. XRF technology is adept at measuring the average deposit loading across a surface and can determine thickness at precise points, with polycapillary optics enabling spot sizes as small as 7.5µm FWHM. Furthermore, the method offers significantly faster cycle times and requires less sample preparation compared to alternative techniques like SEM, producing results within seconds.
