Pd-based chalcogenides for energy conversion electrocatalysis

The research and development of high-performance electrocatalysts are crucial for advancing highly efficient energy conversion technologies. Pd-based chalcogenides, an innovative class of materials, have been extensively studied as electrocatalysts due to their diverse advantages for energy conversion reactions. This review summarizes recent progress in the synthesis, modification, and application of various Pd-based chalcogenides. It begins by presenting four effective synthesis methods with typical examples, followed by strategies for increasing the active sites, adjusting the electronic structure, and optimizing the binding energy with intermediates. The review also explores the applications of representative Pd-S, Pd-Se, and Pd-Te catalysts for electrocatalytic reactions. It is anticipated that this review will inspire further research into the development of advanced Pd-based chalcogenide electrocatalysts.
