Graphite also is chemically inert with high temperature tolerance.\u003c\/p\u003e\n\u003cp\u003eFor these reasons, graphite is often recommended as the counter electrode when screening the electrocatalytic performance of non-precious metal materials or as an alternative counter electrode when evaluating new electrocatalysts. For example, in hydrogen evolution reaction (HER) catalyst studies, graphite is commonly employed to avoid artefacts due to platinum dissolution and redeposition.\u003c\/p\u003e\n\u003cp\u003eHowever, graphite can also be subject oxidation, carbon corrosion and particle shredding, graphite particle detachment and by-product diffusion. This can contaminate or deactivate the working electrodes. Compared to platinum, graphite has a more limited stable potential range and lower catalytic activity for certain reactions. Graphite has limited applications compared to platinum electrodes and it’s not advised for use in harsh conditions.\u003c\/p\u003e\n\u003cp\u003eFor certain applications, alternative counter electrode materials, such as stainless steel or titanium, may be used. This is particularly valubale when improved mechanical durability or compatibility with specific electrolytes is required. For example, where noble metal contamination must be avoided or where long-term stability in corrosive environments is important. However, their electrochemical behaviour should always be considered carefully, as surface oxidation, passivation, or corrosion under certain potentials may influence the overall cell performance.\u003c\/p\u003e\n\u003cfigure\u003e\u003cimg src=\"https:\/\/www.ossila.com\/cdn\/shop\/files\/platinum-coil-electrodes-comparrison.jpg?v=1770383717\" width=\"848\" loading=\"lazy\" alt=\"Coil geometries can increase the surface area of counter electrodes\"\u003e\n\u003cfigcaption\u003ePlatinum Coil Electrode\u003c\/figcaption\u003e\n\u003c\/figure\u003e\n\u003ch2 id=\"counter-electrode-shape-geometry\"\u003eCE Shape and Geometry\u003c\/h2\u003e\n\u003chr\u003e\n\u003cp\u003eSurface area is an important part of counter electrode functionality.

As a non-metal material, graphite significantly cheaper and more earth-abundant than platinum, making it a cost-effective solution for many applications, especially on large-scale uses. Graphite also is chemically inert and high-temperature tolerant, offering a wide range of electrochemical reactions at high temperatures.\u003c\/p\u003e\n\u003cp\u003eHowever, graphite is a carbon material that is subject to oxidation and corrosion which can lead to graphite particle detachment and by-product diffusion, to poison or deactivate the working electrodes.

Electrolysis\u003c\/a\u003e\n\u003cp\u003eUnlike many other electrochemical techniques, which are limited to the diffusion layer, bulk electrolysis (sometimes referred to just ‘electrolysis’) changes the composition of the bulk solution. Bulk electrolysis experiments aim to generate a quantitative conversion such that the amount of substrate consumed is directly proportional to the total consumed charge.\u003c\/p\u003e\n\u003ca href=\"https:\/\/www.ossila.com\/pages\/bulk-electrolysis\"\u003eRead more...\u003c\/a\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Ossila","offers":[{"title":"Single Electrode","offer_id":51098316144856,"sku":"C2025G1","price":60.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0823\/0287\/files\/graphite-rod-counter-electrode-product-photo.jpg?v=1770118399"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0823\/0287\/collections\/counter-electrodes-collection-featured-photo.jpg?v=1770367297","url":"https:\/\/www.ossila.com\/collections\/counter-electrodes.oembed","provider":"Ossila","version":"1.0","type":"link"}
