Proton insertion mechanism with fast reaction kinetics is attracting more and more attention for high-rate and durable aqueous Zn─MnO batteries. However, hydrated Zn insertion reaction accompanied with Jahn-Teller effect and Mn disproportionation generally leads to sluggish rate capability and irreversible structure transformation. Here, carboxyl-carbon nanotubes supported α-MnO nanoarrays (C─MnO) cathode is successfully fabricated by a convent grinding process for high-performance Zn batteries.

Electrocatalytic hydrogenation (ECH) of quinoline provides an eco-friendly and prospective route to achieve the highly value-added generation of 1,2,3,4-tetrahydroquinoline (THQ). Co element has been proven to be the efficient catalytic site for ECH of quinoline, but the rational regulation of the electronic structure of active Co site to improve the activity is still a challenge. Herein, the hierarchical core-shell structure consisting of NiCo-MOF nanosheets encapsulated Cu(OH) nanorods (Cu(OH)@CoNi-MOF) is constructed.

Lattice sulfur-impregnated nanoscale zerovalent iron (S-nFe) has been recognized as a promising groundwater remediation agent. However, little information is available on its reactivity with ubiquitous extracellular antibiotic resistance genes (eARGs) in anaerobic groundwater, and how S content and speciation affect their interactions. Here, the efficient anaerobic degradation of eARGs by S-nFe (6 log within 5 min), resulting in completely inhibited transformation is showed.

Transition metal selenides (TMSe) are promising oxygen evolution reaction (OER) electrocatalysts but act as precursors rather than the actual active phase, transforming into amorphous oxyhydroxides during OER. This transformation, along with the formation of selenium oxyanions and unstable heterointerfaces, complicates the structure-activity relationship and reduces stability. This work introduces novel "layered-hierarchical dual lattice strain engineering" to inhibit the surface reconstruction of NiSe by modulating both the nickel foam (NF) substrate with MoN nanosheets (NM) and the NiSe nanorods-nanosheets catalytic layer (NiSe-NiSe-NiO, NSN) with ultrafast interfacial bimetallic amorphous NiFeOOH coating, achieving the optimized NM/NSN/NiFeOOH configuration.

Integrating mixed electron donor (D) and electron acceptor (A) ligands into metal-organic frameworks (MOFs) is an effective yet relatively unexplored approach for improving the anode performance of hybrid lithium-ion capacitors (HLICs). In this study, using an electron donor 2,6-bis(4'-pyridyl)tetrathiafulvalene and an electron acceptor ,'-bis(5-isophthalic acid) naphthalene diimide as ligands, a new Zn-TTF/NDI MOF () is constructed as a pseudocapacitive anode of HLICs. Crystallographic characterization revealed that MOF adopts a two-dimensional (2D) coordination network.
