In addition to transition metals, which are already well studied for their catalytic properties, a wider choice of elements has now moved into the focus such as alkali metals, alkaline earth metals, rare earth metals, lean metals and metalloids. Some of these when combined with transition metal electrocatalysts can significantly improve performance and contribute to the development of next-generation high-performance electrocatalysts.
However, many of the processes that take place during electrocatalysis -when oxygen or hydrogen is formed — are still not understood in detail. In a review article, an international team of experts guides us through this exciting research field and draws a perspective, sketching the next steps catalyst research could take. “This contribution summarises the current state of knowledge on such unconventional s-, p-, and f-block metal-based materials and makes it comprehensible to a wider community of scientists,” Dr. Prashanth W. Menezes points out and adds: “Further, the essential role of such metals during water splitting electrocatalysis is described in great depth, as well as the modification strategy that should be considered when one wants to utilize them to mediate non-noble-based electrocatalysts. We hope to significantly accelerate research and development of novel, innovative catalyst materials with this review article.”
