Article Abstract

A novel three-dimensional catalytic nanodiode composed of a Pt thin film on TiO nanotubes was designed for the efficient detection of the flux of hot electrons, or chemicurrent, under hydrogen oxidation. We verify a significant increase in the chemicurrent from the fast transport of electrons across the ordered supporting oxide layer. This study demonstrates the direct detection of hot electrons on well-ordered TiO nanotubes during the catalytic reaction.

Lignin, a negatively charged, three-dimensional natural biopolymer, serves as an ideal support for metal catalysts due to its abundant functional groups and tunable chemical properties, which enable strong metal coordination and effective immobilization. Herein, we demonstrate a lignin-mediated Co/O co-doped AgS, symbolized as L-AgCoOS, bimetal oxysulfide catalyst via a facile hydrolysis method for the efficient reduction of toxic phenolic compounds (4-nitrophenol, 4-NP), organic dyes (methyl orange (MO), methylene blue (MB), rhodamine B (RhB), and heavy metal ions Cr(VI)) under dark conditions. Lignin, used to immobilize catalysts, also contributes to increasing the number of active catalytic sites and enhancing catalytic activity.

Organic nucleophile-assisted natural seawater electrolysis has emerged as a promising strategy for green hydrogen production by significantly reducing energy consumption. Among Ni-based electrocatalysts, NiMoO has drawn attention for its activity in both oxygen evolution reaction (OER) and urea oxidation reaction (UOR). However, its practical application is hindered by severe surface passivation, particularly at industrial current densities (e.

Transition metal fluorides because of the high electronegativity of fluorine may enhance the local electron density of the metal sites and promote water molecule dissociation and charge transfer. However, enhancing the intrinsic activity of fluorides to improve material stability remains a challenge. Herein, we develop an innovative four-step synthetic strategy (electrochemical deposition → co-precipitation → ligand exchange → in situ fluorination) to engineer three-dimensional porous Fe-doped CoF nanocubes vertically anchored on MXene (Fe-CoF/MXene/NF).

Electrochemical nitrogen fixation-a sustainable pathway for converting abundant N into NH using renewable energy-holds transformative potential for revolutionizing artificial nitrogen cycles. Nevertheless, even the state-of-the-art catalytic systems also suffer from inadequate N adsorption capacity, which critically limits ammonia production rates and Faradaic efficiency (FE). To overcome this bottleneck, we strategically leveraged the antiferroelectric properties of SnO to establish dipole-dipole interactions with N molecules, synergistically enhancing both N adsorption and activation kinetics.

The enantioselective construction of quaternary carbon stereocenters bearing amine functionalities represents a significant challenge in organic synthesis despite their prevalence in pharmaceutically active compounds. Herein, we report a versatile metallaphotoredox platform for the asymmetric incorporation of amine fragments onto quaternary carbons via coupling of alkene-tethered aryl bromides with readily available α-silylamines. This transformation proceeds under mild conditions without requiring organometallic reagents or stoichiometric reductants.
