In promising transition metal sulfide catalysts, the extraordinary instability under air exposure and oxygen evolution reaction (OER) catalysis severely degrades their activity stability in electrochemical water splitting reaction, inhibiting practical applications. Herein, guided by a theoretical mechanism study, it is disclosed that adsorbing ability electronic interaction for molecular will be significantly weakened nickel disulfide (NiS2) constructing an electron-deficient distribution...
Spinel oxides, representing an emerging class of highly active catalysts for oxygen evolution (OER), suffer from weak covalency metal d and p orbitals their typical crystal structure, which generally proceeds the OER with adsorbate mechanism (AEM) pathway. For activating lattice in spinel oxides to bypass scaling relationship limitation AEM, we herein grow sulfate salts on octahedral sites NiFe2O4 introduce Ni4+ cations Ni vacancies sites, exhibit remarkable performance overpotential 293 mV...
The sluggish kinetics of oxygen reduction reaction (ORR) and unsatisfactory durability Pt-based catalysts are severely hindering the commercialization proton-exchange-membrane fuel cells (PEMFCs). In this work, lattice compressive strain Pt-skins imposed by intermetallic cores is tailored for highly effective ORR through confinement effect activated nitrogen-doped porous carbon (a-NPC). modulated pores a-NPC not only promote intermetallics with ultrasmall size (average <4 nm), but also...
Tuning the d-orbital electronic configuration of active sites to achieve well-optimized adsorption strength oxygen-containing intermediates toward reversible oxygen electrocatalysis is desirable for efficient rechargeable Zn-Air batteries but extremely challenging. Herein, this work proposes construct a Co@Co3 O4 core-shell structure regulate Co3 enhanced bifunctional electrocatalysis. Theoretical calculations first evidence that electron donation from Co core shell could downshift d-band...
A novel and efficient CuI-catalyzed synthesis of 2,3,5-trisubstituted furans was developed via coupling cyclization gem-difluoroalkenes with active methylene carbonyl compounds such as 1,3-dicarbonyl compounds, acetoacetonitrile, phenylsulfonylacetone the assistance a base. Commercial availability substrates or reagents, good to high isolated yields, excellent functional group compatibility make this transformation powerful tool for various furans. plausible mechanism involving allenyl...

Abstract Modulating the electronic configuration of substrate to achieve optimal chemisorption toward polysulfides (LiPSs) for boosting polysulfide conversion is a promising way efficient Li–S batteries but filled with challenges. Herein, Co/CoS 2 heterostructure elaborately built tuning d‐orbital structure CoS high‐performance electrocatalyst. Theoretical simulations first evidence that Co metal as electron donator can form built‐in electric field and downshift d‐band center, leading...
Rational tailoring of the electronic structure at defined active center reconstructed metal (oxy)hydroxides (MOOH) during oxygen evolution reaction (OER) remains a challenge. With guidance density functional theory (DFT), herein dual-site regulatory strategy is reported to tailor d-band Co site in CoOOH via controlled transfer Ru─O─Co─O─Fe bonding structure. Through bridged O
A new low-cost, high throughput method was developed for fabricating large area quantized magnetic disks (QMDs) using nanoimprint lithography (NIL), electroplating, and chemical mechanical polishing. Perpendicular QMDs with a density of 18 Gbit/in.2 good uniformity over an 4 cm×4 cm (total 45 Gbit) have been achieved, as well longitudinal 30 The NIL molds the perpendicular were fabricated double grating mold. properties both types studied by force microscopy.
Two radical-mediated cascade couplings of N-alkyl-N-methacryloylbenzamides with different ethers and arylsulfonohydrazides to generate ether- arylsulfonyl-substituted isoquinoline-1,3(2H,4H)-dione derivatives were developed. Both casccades proceeded via initially triggered functionalization the alkene functions N-alkyl-N-methacryloylbenzamides, followed by ortho radical cyclizations onto aromatic ring give in good yields. These highly functionalized drug-like molecules will be valuable drug...

The development of highly active and stable electrocatalysts toward oxygen reduction reaction (ORR) hydrogen evolution (HER) is a key for commercial application fuel cells water splitting. Here, we report Pt nanoparticles (NPs) encapsulated in ultrathin two-dimensional (2D) carbon layers derived from the 2D metal-organic framework precursor (ZIF-67). Electrochemical tests reveal that our approach not only stabilized NPs successfully but also boosted activities ORR HER. We found catalysts...
