Catalytic Decomposition of Nitrogen Oxides by Bimetallic Catalysts Synthesized by Dielectric Barrier Discharge Plasma Technology

E3S Web of Conferences, 2018
Nitrous oxide (N2O) is a common greenhouse gas and urgent need to be contained. Direct catalytic decomposition of N2O by high activity catalyst into N2 and O2 is a low-cost and harmless method.

Z‐Scheme Water Splitting Systems Based on Solid‐State Electron Conductors

Advanced Functional Materials, EarlyView.
This review examines the latest advances in Z‐scheme overall water splitting (OWS) systems for solar hydrogen production. These systems consist of suspended or immobilized hydrogen evolution photocatalysts (HEPs) and oxygen evolution photocatalysts (OEPs).

Quantifying Electron and Ion Transfers in Contact Electrification with Ionomers

Advanced Functional Materials, EarlyView.
The concurrent existence of both electron and ion transfers in solid‐ionomer contact electrification is reported. The ion transfer contributes significantly to the process of contact electrification, especially at high humidity, although only less than 2% of ions participate in the ion transfer, suggesting that there is room for further performance ...

Highly Scalable, Raspberry‐Like Microbeads with Nano‐/Micro‐Confined Hybrid Hydrogel Desiccants for Rapid Atmospheric Water Harvesting

Advanced Functional Materials, EarlyView.
A scalable nano‐/micro‐confinement strategy is developed, where polyacrylamide (PAM)‐LiCl hybrid desiccants are confined within hollow nanoparticles (HNPs) and assembled into raspberry‐like microbeads. The beads have a hydrogel‐rich core and an NP‐rich shell for fast absorption and desorption, releasing water 13.6 L kg⁻¹ day⁻¹.

Moving from Classical Ru-NHC to Neutral or Charged Rh-NHC Based Catalysts in Olefin Metathesis

Molecules, 2016
Considering the versatility of oxidation states of rhodium together with the successful background of ruthenium-N-heterocyclic carbene based catalysts in olefin metathesis, it is envisaged the exchange of the ruthenium of the latter catalysts by rhodium,

Laser‐Induced Graphene from Waste Almond Shells

Advanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Double Helical Plasmonic Antennas

Advanced Functional Materials, EarlyView.
Plasmonic double helical antennas funnel circularly polarized light to the nanoscale, offering strong chiroptical interaction and directional light emission. Extending a single helix design tool, this study combines numerical modeling with experimental validation, revealing large, broadband dissymmetry factors in the visible range.
