Triggering Low-Temperature Chlorine Activation via Interfacial Ru–O–Mn Coordination Bridges for Robust Waste Incineration Flue Gas Mercury Oxidation

Hongyuan Qi, Yurui Fan, Yongpeng Ma, Mingze Jiao et autres

Municipal solid waste incineration (MSWI) is an important anthropogenic source of elemental mercury (Hg0) emissions. In MSWI flue gas treatment, achieving efficient Hg0 oxidation relies on the active participation of HCl under typical downstream operating conditions (<200 °C). However, the activation of …

Speciation Detection Deciphering C 2 H 2 /Cl-Driven Mercury Escape Mechanisms in PVC Production

Mingming Wang, Yurui Fan, Qinyuan Hong, Wenjun Huang et autres

Mercury emissions from acetylene hydrochlorination processes in polyvinyl chloride (PVC) production pose severe environmental risks yet remain poorly quantified due to methodological limitations in high-reactivity C 2 H 2 /HCl atmospheres. We reported an advanced operando mercury speciation platform named PVC-OHM, engineered …

An Engineered Au-MXene Sorption Trap Enables Dual-Channel Ultrafast and Selective Detection of Trace Gaseous Elemental Mercury

Jia Chen, Li Yang, Qinyuan Hong, Yiqi Feng et autres

Accurate detection of trace atmospheric mercury is critical for toxicological assessment and environmental protection. However, achieving parts per billion-level sensitivity with high selectivity between gaseous elemental mercury (Hg 0 ) and oxidized mercury (Hg 2+ ) remains a significant challenge. Here, we …

Low-Coordinated Polysulfide Species on Metal Sulfide Enabled Superior Gaseous Mercury Removal from Natural Gas

Qinyuan Hong, Haomiao Xu, Cancan Ling, Zhisong Liu et autres

The pursuit of efficient natural gas utilization is inherently linked to thorough purification of its contaminants. Traditional purification techniques, while adept at removing sulfur-containing acid gases (e.g., H 2 S) and hydrocarbons, have overlooked a critical aspect: the efficient management of mercury, …

Revealing the Jahn–Teller Mitigating Complexity of Se-Anchored Mn Oxides for Superior SO2 Resistance in Gaseous Molecular Oxygen Activation

Haomiao Xu, Qinyuan Hong, Jia’nan Wang, Jun Lei et autres

Manganese oxides have emerged as promising catalysts for the low-temperature activation of molecular oxygen (O 2 ), crucial for the catalytic oxidation and removal of gaseous pollutants. However, the undesired Jahn–Teller (J-T) effects associated with the Mn iv /Mn iii redox couple, …

In-situ low-temperature sulfur CVD on metal sulfides with SO2 to realize self-sustained adsorption of mercury

Qinyuan Hong, Haomiao Xu, Xiaoming Sun, Jiaxing Li et autres

Abstract Capturing gaseous mercury (Hg 0 ) from sulfur dioxide (SO 2 )-containing flue gases remains a common yet persistently challenge. Here we introduce a low-temperature sulfur chemical vapor deposition (S-CVD) technique that effectively converts SO 2 , with intermittently introduced H …
