Sustainable chemical applications need to be able to employ renewable energy sources, renewable raw materials, and earth-abundant elements. However, to date many techniques have only been possible with the use of expensive precious metals or rare earth metals, the extraction of which can have serious environmental impacts. A team of researchers has now achieved a breakthrough in the use of chromium, an abundant base metal. https://www.sciencedaily.com/releases/2022/06/220603100203.htm
