Iodine Redox-Mediated Electrolysis for Energy-Efficient Chlorine Regeneration from Gaseous HCl
Zhao, Yun; Gu, Shuang; Gong, Ke; Zheng, Jie; Wang, Junhua; Yan, Yushan (Electrochemical Society, Inc., 2017-05-05)Hydrogen chloride (HCl) by-product is often produced from chlorine-consuming processes. Traditional electrochemical processes for converting HCl to chlorine (Cl-2) are completed by anodic oxidation reaction coupled with ... -
Low-voltage gaseous HCl electrolysis with an iron redox-mediated cathode for chlorine regeneration
Zhao, Yun; Gu, Shuang; Gong, Ke; Zheng, Jie; Wang, Junhua; Yan, Yushan (John Wiley & Sons, Inc., 2017-08-28)Gaseous HCl as a by-product is often produced from chlorination processes using Cl-2 gas. Onsite Cl-2 regeneration from HCl is highly desirable as it eliminates the need to buy new Cl-2 and dispose HCl waste. A gaseous HCl ... -
A new alkali-stable phosphonium cation based on fundamental understanding of degradation mechanisms
Zhang, Bingzi; Kaspar, Robert B.; Gu, Shuang; Wang, Junhua; Zhuang, Zhongbin; Yan, Yushan (John Wiley & Sons, Inc., 2016-09-08)Highly alkali-stable cationic groups are a critical component of hydroxide exchange membranes (HEMs). To search for such cations, we studied the degradation kinetics and mechanisms of a series of quaternary phosphonium ... -
Relating alkaline stability to the structure of quaternary phosphonium cations
Zhang, Bingzi; Long, Hai; Kaspar, Robert B.; Wang, Junhua; Gu, Shuang; Zhuang, Zhongbin; Pivovar, Bryan; Yan, Yushan (Royal Society of Chemistry, 2018-07-25)Alkali-stable quaternary phosphonium (QP) is a type of cationic group for hydroxide exchange membranes (HEMs). To elucidate the relationship between structure and alkaline stability, we investigated the kinetics and ...
