Heterojunction catalysts for urea oxidation reaction

Year: 2025

Type: article

Abstract: The electrocatalytic urea oxidation reaction (UOR) is a promising strategy for addressing both environmental remediation and energy conversion challenges. Recently, heterojunction catalysts have gained significant attention due to their enhanced catalytic activity and stability. This review provides a comprehensive analysis of recent advancements in heterojunction catalysts for UOR. We begin by outlining the fundamental principles of UOR and key catalyst evaluation parameters. Next, we discuss the unique features of heterojunction catalysts, highlighting their structural and electronic advantages. The applications of various heterojunction architectures—including those based on transition metals, alloys, metal (hydro)oxides, chalcogenides, pnictides, and metal–organic frameworks—are then examined in detail. A particular focus is placed on structure–performance relationships and rational design strategies to optimize catalytic efficiency. This review offers valuable insights into the development of next-generation heterojunction catalysts for efficient and sustainable UOR applications.
