Abstract
The intensifying global demand for clean and sustainable energy solutions has accelerated the quest for high-performance electrocatalysts capable of efficiently mediating key electrochemical reactions—most notably, the oxygen evolution reaction (OER) and the oxygen reduction reaction (ORR). To overcome intrinsic drawbacks of pristine chalcogenide materials—such as limited electroactive surface area and inherently poor electrical conductivity—research efforts have increasingly focused on engineering chalcogenide-based nanocomposites via strategic incorporation with conductive matrices, heterostructured architectures, and multifunctional co-catalysts. Transition metal chalcogenides (TMCs), in particular, offer significant potential due to their versatile redox behavior, variable oxidation states, and electronically tunable layered structures. This chapter offers an in-depth exploration of recent advances in chalcogenide-based nanocomposites, which have emerged as highly promising candidates for next-generation OER and ORR electrocatalysis.
