摘要
Lead dioxide (PbO2) materials have been widely employed in various fields such as batteries, electrochemical engi-neering, and more recently environmental engineering as anode materials, due to their unique physicochemical prop-erties. Key performances of PbO2 electrodes, such as energy efficiency and space-time yield, are influenced by morphological as well as compositional factors. Micro-nano structure regulation and decoration of metal/non-metal on PbO2 is an outstanding technique to revamp its electrocatalytic activities and enhance environmental engineering efficiency. The aim of this review is to comprehensively summarize the recent research progress in the morphology control, the structure constructions, and the element doping of PbO2 materials, further with many environmental ap-plication cases evaluated. Concerning electrochemical environmental engineering, the lead dioxide employed in chemical oxygen demand detection, ozone generators, and wastewater treatment has been comprehensively reviewed. In addition, the future research perspectives, challenges and the opportunities on PbO2 materials for environmental applications are proposed.
