We introduce a facile strategy to upcycle lignin waste to valuable activated carbon (AC). Unlike conventional preparation processes of AC, such as high-temperature carbonization above 600 °C followed by chemical or physical activation, we synthesize

[Mo3S13]2– clusters have become known as one of the most efficient catalysts for the hydrogen evolution reaction (HER) because most of the sulfur (S) atoms in the cluster are exposed, resulting in many active sites. However, the origin of the clust
