Dynamic Active Site Evolution in Lanthanum‐Based Catalysts Dictates Ethane Chlorination Pathways

open access: yesAngewandte Chemie, EarlyView.
LaOCl‐catalyzed C2H6 chlorination offers a low‐carbon route for polyvinyl chloride synthesis, yet structural evolution occurs under Cl2 conditions. We establish structural sensitivity in La‐catalyzed chlorination, and elucidate the size‐dependent chlorophilicity of LaCl3 and the role of hydroxyl groups in overchlorination, highlighting stabilization of

Optimized Synthesis and Characterization of Janus RhSeCl with Uniform Anionic Valences, Nonlinear Optical and Optoelectronic Properties

open access: yesAdvanced Science, EarlyView.
Janus RhSeCl exhibits a facial heteroatom configuration and uniform anionic valences with Se and Cl in the −1 oxidation state, stabilizing the unique structure. The symmetry‐breaking nature enables promising nonlinear optical and optoelectronic performance, providing new insights into two–dimensional (2D) Janus materials and broadening their potential ...

Harnessing Bifunctional N‐Benzoyloxyamides for Photoredox Amidative Dual Functionalizations of Alkenes

open access: yesAngewandte Chemie, EarlyView.
A novel photocatalytic strategy is presented for intermolecular amidative dual functionalization of alkenes using N‐benzoyloxyamides as bifunctional N─O reagents. The method enables efficient olefin 1,2‐amidooxygenation and significantly extends its reactivity to encompass amidoazidation, diamination, and formal anti‐Markovnikov hydroamidation.

Peroxide‐Driven Nitrogen Fixation Reactions for Energy Storage Applications

open access: yesAdvanced Energy Materials, EarlyView.
Sustainable ammonia synthesis from air as a hydrogen energy carrier and storage medium is demonstrated via an efficient dual‐step electrochemical approach at ultralow overpotential (−0.1 V vs. RHE). Atmospheric nitrogen is first oxidized to nitrate using in situ generated peroxide, then directly converts to ammonia on the same electrode, achieving ...

Low‐Cost, High‐Efficiency Organic Solar Cells Based on Ecofriendly Processing Solvent

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
A low‐complexity, cost‐effective donor material, PTQ10, combined with the high‐efficiency acceptor materials, BTP‐eC9 and Y6, demonstrates excellent performance with the ecofriendly solvent o‐xylene (XY) instead of the traditional chloroform (CF) for the spin‐coating method.

Electrodialysis of LiPF6 in Aqueous Solution for Wastewater Treatment in Hydrometallurgical Recycling of Lithium‐Ion Batteries

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
Hydrometallurgical recycling of lithium‐ion batteries produces wastewater containing PF6− and Li+, which must be removed and recovered, respectively. This study pioneers electrodialysis using anion exchange membrane and cation exchange membrane to separate PF6− and Li+.

Chlorine‐dopant dynamically stabilizes Cu0/Cu+ active sites for selective CO2 electroreduction to multicarbon products

open access: yesAIChE Journal, EarlyView.
Abstract The electrochemical CO2 reduction reaction (CO2RR) to multicarbon (C2+) products faces significant challenges rooted in the high energy barriers of C–C coupling, which can be addressed through dopant‐mediated stabilization of Cu+ species on Cu catalysts.

Environmental Behavior, Sources, and Effects of Chlorinated Polycyclic Aromatic Hydrocarbons

open access: yesThe Scientific World Journal, 2007
The environmental sources and behaviors of chlorinated 2- to 5-ring polycyclic aromatic hydrocarbons (ClPAHs). ClPAHs are ubiquitous contaminants found in urban air, vehicle exhaust gas, snow, tap water, and sediments.
