Economic Low‐Carbon Chemical Production via Paired Electrolysis of Carbon Monoxide (CO) and 5‐hydroxymethylfurfural (HMF)

Advanced Materials, EarlyView.
Replacing CO2 with CO at the cathode and integrating a catholyte‐layer membrane electrode assembly transforms paired electrolysis into a stable platform for co‐producing ethylene and 2,5‐furandicarboxylic acid. Combined experimental and techno‐economic analyses identify carbon monoxide and 5‐hydroxymethylfurfural as the most compatible pairing ...

2H-Thiopyran-2-thione sulfine, a compound for converting H2S to HSOH/H2S2 and increasing intracellular sulfane sulfur levels

Nature Communications
Reactive sulfane sulfur species such as persulfides (RSSH) and H2S2 are important redox regulators and closely linked to H2S signaling. However, the study of these species is still challenging due to their instability, high reactivity, and the lack of ...

Targeted Modulation of d‐Band Center in MoS2 Interlayer With n‐Type Co/Fe Dopants Accelerating Sulfur Reaction Kinetics in Lithium‐Sulfur Batteries

Advanced Materials, EarlyView.
A targeted modulation of the MoS2 electronic structure is achieved via substitutional n‐type Co/Fe co‐doping. This strategy triggers S‐mediated d‐p hybridization, optimizing the binding affinity with polysulfides to establish a volcano‐shaped relationship between the d‐band center and catalytic activity.
