Description
Glen Hebberd and co-authors make two rare metal sulfides by gentle chemical routes, including one never reported before, in a 2026 study. Three-metal sulfides are wanted for batteries, solar cells, and catalysts because they absorb light well and conduct charge, but they are harder to make than oxides. One new compound joins lanthanum, silver, and sulfur; the other swaps silver for copper.
The silver compound formed at low temperature through a reaction that swaps negative ions while keeping the structure frame. The copper one formed by grinding-driven chemistry. Computer work showed the energy cost of forming the new compound is small, which fits the easy synthesis. Structural study links that ease to the larger size of the silver ion compared with copper. Light tests gave both materials a band gap near two electron volts, in the range useful for light-driven uses.
