Femtosecond pulsed laser deposition of nanostructured TiO2 films in atmosphere

AIP Advances, 2017
Nanostructured TiO2 films were grown on a monocrystalline silicon substrate by a femtosecond pulsed laser ablating a Ti target in atmosphere without a vacuum chamber. FESEM and XPS results showed that the TiO2 nanomaterials prepared by this method have a

Removal of Steroid Hormone Micropollutants by an Electrochemical Carbon Nanotube Membrane Flow‐Through Reactor: Role of Concentration and Degradation Mechanisms

Advanced Functional Materials, EarlyView.
A flow‐through electrochemical membrane reactor equipped with a carbon nanotube membrane eliminates the mass transfer limitation, achieving removals >97.5% for steroid hormone (SH) micropollutants through electrochemical adsorption and degradation, over a broad initial concentration varying from 50 to 106 ng L−1.

Constructing a MoS2 QDs/CdS Core/Shell Flowerlike Nanosphere Hierarchical Heterostructure for the Enhanced Stability and Photocatalytic Activity

Molecules, 2016
MoS2 quantum dots (QDs)/CdS core/shell nanospheres with a hierarchical heterostructure have been prepared by a simple microwave hydrothermal method. The as-prepared samples are characterized by XRD, TEM, SEM, UV-VIS diffuse reflectance spectra (DRS) and ...

Enhancing the Photocatalytic Performance of Carbon Nitrides Through Controlled Local Structure Modification

Advanced Functional Materials, EarlyView.
This work utilizes poly(heptazine imides) as a model system to demonstrate how fine‐tuning the crystal structure influences the photocatalytic properties of layered carbon nitrides in the hydrogen evolution reaction. In particular, the nature of rotational defects and the hydration shell of cations are key contributors to enhanced hydrogen evolution ...

All‐Inorganic InP/ZnSe/ZnS Quantum Dots with Chalcogenidometallate Ligands for Biosolar Catalysis

Advanced Functional Materials, EarlyView.
Intrinsic charge transfer limitations in core/shell QDs are addressed through a ligand‐induced band offset engineering (LBOE) strategy utilizing metal chalcogenide complex (MCC) ligands. The MCC‐functionalized InP/ZnSe/ZnS QDs exhibited remarkably augmented hydrogen peroxide (H2O2) generation.

Protophilic TiOx/Ti3C2Tz Nanosheets for Hyper‐Efficient Closed‐Loop Pd Recycling

Advanced Functional Materials, EarlyView.
Protophilic TiOx/Ti3C2Tz NSs enable selective Pd(II) recovery through in situ adsorption‐reduction into Pd(0) NPs from spent catalyst leachates and industrial wastewaters. The resulting Pd/NS composites are directly upcycled as efficient HER electrocatalysts or regenerated for reuse through controlled surface regeneration.
