Deciphering the poisoning effect of sulfate on a perovskite-derived IrOxHy catalyst for water oxidation in acid by Seow, Justin Zhu Yeow, Chen,Yubo, Ge, Jingjie, Fisher, Adrian C., Xu, Jason Zhichuan

“…This phenomenon is unique to a reconstructed surface undergoing continuous cation leaching from the perovskite-oxyhydroxide interface, in which SrSO4 precipitate blocks electrolyte-accessible IrOxHy-walled channels, preventing further Sr and Co ion leaching from the interface and dehydrating the isolated portion of the blocked channels, resulting in a reduction in the number of Ir active sites and causing the catalyst to have an OER performance stability inferior to commercial IrO2…”

Degradation of carbonated reactive MgO-based concrete exposed to nitric acid by Muthu Murugan, Kumar, Sanjeev, Yang, En-Hua, Unluer, Cise

“…The use of FA led to a lower hydration and subsequent carbonation due to the lower RMC content, thereby limiting initial strength development. While the leaching of Mg-based phases into the external solution was recorded, most hydrate and carbonate phases were still present after acid exposure. …”

Simplified framework for efficient utilization of municipal solid waste incinerator bottom ash as construction material via systematic classification and characterization by Chen, Zhitao, Kumar, Dhanendra, Zhu, Weiping, Liu, Yiquan, Yang, En-Hua

“…A comprehensive characterization of chemical/mineralogical compositions of classified IBA using state-of-the-art techniques was then conducted to understand the properties of each class, which aid in determining the appropriate applications for each category of classified IBA. The leaching behavior of the classified IBA was also studied to evaluate the environmental safety of the classified IBA classes and suggested avoiding categories with high concentrations of leachable toxic elements. …”

Exceptionally active iridium evolved from a pseudo-cubic perovskite for oxygen evolution in acid by Chen, Yubo, Li, Haiyan, Wang, Jingxian, Du, Yonghua, Xi, Shibo, Sun, Yuanmiao, Sherburne, Matthew, Ager, Joel W., Fisher, Adrian C., Xu, Jason Zhichuan

“…During the electrochemical cycling, a surface reconstruction, with Sr and Co leaching, over SrCo0.9Ir0.1O3-δ occurs. Such reconstructed surface region, likely contains a high amount of structural domains with corner-shared and under-coordinated IrOx octahedrons, is responsible for the observed high activity.…”
