Advances and Perspectives in Graphene‐Based Quantum Dots Enabled Neuromorphic Devices

Advanced Science, EarlyView.
Graphene‐based QDs are zero‐dimensional carbon nanomaterials with pronounced quantum confinement and tunable electronic structures. Herein, we summarize their synthesis strategies and functionalization methods, and highlight their functional roles and operating mechanisms in devices, as well as recent advances in neuromorphic electronics. We anticipate

Plasmonic Hafnium Nitride Nanoparticle‐Decorated Graphitic Carbon Nitride for Plasmon‐Enhanced Photocatalytic Dye Degradation

Nano Select
Photocatalytic dye degradation under visible light irradiation is restricted by the poor light absorption and the rapid recombination of photogenerated electron‐hole pairs in traditional materials, such as graphitic carbon nitride (g‐CN), hindering their

Grafting Boron Nitride Nanotubes:  From Polymers to Amorphous and Graphitic Carbon

, 2007
In this article, using an atom transfer radical polymerization approach, for the first time polystyrene (PS) and polymethyl methacrylate (PMMA) were grafted covalently on boron nitride nanotubes (BNNTs). Then, a technique was developed to fabricate novel

Ferroelectric Catalysts in the Hydrogen Evolution Reaction: A Perspective

Advanced Science, EarlyView.
This perspective summarizes recent advances in ferroelectric (FE) catalysts for the hydrogen evolution reaction (HER). It first introduces HER fundamentals and FE mechanisms, then classifies FE catalysts into single‐phase, single‐atom‐modified, heterostructured, and other engineered types, with representative examples.

Asymmetric Single‐Atom Catalysts Govern Diffusible and Non‐Diffusible Non‐Radical Pathways for Selective Degradation of Antibiotic Resistance Genes

Advanced Science, EarlyView.
Asymmetric single‐atom metal‐nitrogen‐carbon catalysts modulate the non‐radical pathway during peroxymonosulfate (PMS) activation. A fundamental contrast was revealed between diffusible singlet oxygen (1O2) and non‐diffusible electron‐transfer pathways (ETP) in antibiotic resistance gene (ARG) degradation.

Metal-functionalized single-walled graphitic carbon nitride nanotubes: a first-principles study on magnetic property

Nanoscale Research Letters, 2011
The magnetic properties of metal-functionalized graphitic carbon nitride nanotubes were investigated based on first-principles calculations. The graphitic carbon nitride nanotube can be either ferromagnetic or antiferromagnetic by functionalizing with ...

Triazine-based graphitic carbon nitride: a two-dimensional semiconductor [PDF]

, 2014
Graphitic carbon nitride has been predicted to be structurally analogous to carbon-only graphite, yet with an inherent bandgap. We have grown, for the first time, macroscopically large crystalline thin films of triazine-based, graphitic carbon nitride ...

Atomically Correlated Phosphorus–Sulfur Sites in Carbon Nitride for Efficient Hydrogen Peroxide Production

Advanced Science, EarlyView.
Atomically correlated phosphorus–sulphur sites are introduced into graphitic carbon nitride to regulate charge distribution, suppress localized trapping, and enhance oxygen activation. The resulting metal‐free photocatalyst selectively promotes the two‐electron oxygen reduction pathway, enabling efficient hydrogen peroxide production in pure water ...

Revealing the Nanoscale Morphology Changes of Polymer Electrolyte Membrane Fuel Cell Catalyst Layers due to Conditioning

Advanced Science, EarlyView.
We apply ex situ and in situ scanning transmission X‐ray microscopy to reveal the structural degradation of polymer electrolyte membrane fuel cell catalyst layers due to conditioning and thermal heating of the catalyst coated membrane. We observe a redistribution of the ionomer and carbon‐black in the catalyst layer, as well as nanoscale membrane ...
