Continuous Unsteady-State De-NO(x) System via Tandem Water-Gas Shift, NH(3) Synthesis, and NH(3)-SCR under Periodic Lean/Rich Conditions.
Zhang N, Qian Y, Toyao T, Shimizu KI. Zhang N, et al. Environ Sci Technol. 2023 Dec 5;57(48):19584-19593. doi: 10.1021/acs.est.3c06390. Epub 2023 Nov 17. Environ Sci Technol. 2023. PMID: 37976507
Herein, we report a new de-NO(x) system using cyclic feeds of rich and lean gas mixtures with PGM-free catalysts. Initial catalyst screening tests showed that Cu/CeO(2) with 5 wt % Cu loading was the most suitable for the water-gas shift reaction (WGS, CO + H …

Lean-water hydrogel electrolyte for zinc ion batteries.
Wang Y, Li Q, Hong H, Yang S, Zhang R, Wang X, Jin X, Xiong B, Bai S, Zhi C. Wang Y, et al. Nat Commun. 2023 Jul 1;14(1):3890. doi: 10.1038/s41467-023-39634-8. Nat Commun. 2023. PMID: 37393327 Free PMC article.
SPEs can enhance the stability of anodes, but they typically possess low ionic conductivities and result in high impedance. Here, we develop a lean water hydrogel electrolyte, aiming to balance ion transfer, anode stability, electrochemical stability window and resistance. …

Emission of Toxic HCN During NO(x) Removal by Ammonia SCR in the Exhaust of Lean-Burn Natural Gas Engines.
Zengel D, Koch P, Torkashvand B, Grunwaldt JD, Casapu M, Deutschmann O. Zengel D, et al. Angew Chem Int Ed Engl. 2020 Aug 17;59(34):14423-14428. doi: 10.1002/anie.202003670. Epub 2020 Jul 1. Angew Chem Int Ed Engl. 2020. PMID: 32391644 Free PMC article.
Reducing greenhouse gas and pollutant emissions is one of the most stringent priorities of our society to minimize their dramatic effects on health and environment. Natural gas (NG) engines, in particular at lean conditions, emit less CO(2) in comparison to c …
