Doped Perovskite Oxides as Oxygen Electrocatalysts for Electrolyzers and Fuel Cells
摘要
Abstract
Electrolyzers and fuel cells,with high theoretical conversion efficiency,zero carbon emission,low noise,and other ad-vantages,are promising energy conversion devices.They play crucial roles in promoting the sustainable development of large-scale,long-term renewable energy storage and distributed power generation,and in achieving the goals of carbon peaking and carbon neutral-ity.However,the current energy efficiency is seriously limited by the lack of low-cost,highly active and stable oxygen electrocatalysts for the oxygen evolution reaction(OER,anode of electrolyzer)and the oxygen reduction reaction(ORR,cathode of fuel cell).Among various innovative catalysts,perovskite oxides possess multiple advantages,including abundant composition and structure,adjustable structure,high stability,low-cost,etc.,attracting wide attention as a generation of promising electrocatalysts.Nevertheless,their low electronic conductivity and inferior intrinsic activity seriously block the practical application.To address these issues,extensive efforts have been devoted to modifying perovskites,such as regulating the structure,physical and chemical properties,and the defect structure,toward enhancing the electronic conductivity and activity through doping engineering strategies.In this review,we summa-rize the development of doped perovskite oxides for electrocatalytic oxygen evolution and reduction toward electrolyzers and fuel cells.Firstly,advantages and challenges of perovskite oxides as oxygen electrocatalysts in electrolyzers and fuel cells were introduced.Fur-thermore,the typical design considerations of the perovskite oxide electrocatalysts were analyzed,including the high intrinsic activ-ity,high density of active sites,sufficient electron/mass transfer,long-term durability,low cost,etc.Next,various doping strategies according to the dopant positions in perovskite oxides were described.Importantly,representative doped perovskite oxides in electro-lyzers and fuel cells were introduced,highlighting the regulation role in lattice and electron structures,physical and chemical proper-ties,and the corresponding correlations with the enhancement of electrocatalytic activity.Finally,we discuss the challenges of doped perovskite oxide electrocatalysts,including precise large-scale synthesis,real active phase and the accurate relationship with catalytic performance and long-term stability for the practical application.Prospects were also offered to address these issues,providing valu-able guidance for rational design and controllable synthesis of high-performance perovskite oxide electrocatalysts.关键词
