From Single Atoms to Nanoparticles: Pathways Toward Efficient and Durable Pt/TiO2 Photocatalysts

Advanced Functional Materials, EarlyView.
Platinum single atoms on TiO2 nanosheets evolve into clusters and nanoparticles under ethanol photoreforming and thermal treatments. By controlling deposition and post‐treatments, particle size and location on specific facets are modulated. The study reveals how stability pathways determine efficiency, guiding the design of more durable photocatalysts.

Stabilization of Miscible Aqueous Phases via Diffusion‐Controlled Multifunctional Nanoparticle‐Ligand Complexation

Advanced Functional Materials, EarlyView.
This study presents a versatile approach to harnessing miscible aqueous domains, enabling liquid‐in‐liquid compartmentalization using a barrier formed in situ rather than bulk immiscibility. The barrier forms upon the complexation of multifunctional nanoparticles and ligands at the contact boundary of aqueous phases.

Perfluorinated ion exchange membrane.

Journal of Ion Exchange, 1995
フッ素系イオン交換膜の膜素材ポリマーの特性と, 食塩電解用隔膜の膜構造について概説した。電解用隔膜には, 高い電流効率と低い電気抵抗, および高い機械的強度が要求される。これらを達成するため現状の工業用膜は, 多層の樹脂層をPTFE織布で補強した複合膜構造となっている。陰極側の樹脂層には, カルボン酸をイオン交換基とするポリマーのみが高濃度の苛性ソーダ中で高い電流効率を実現するため, カルボン酸ポリマーが用いられる。陽極側の樹脂層には, イオン導伝性の高いカルボン酸あるいはスルホン酸ポリマーが用いられている。また, より高度な複合膜設計に基づいて, 50%力性ソーダを直接電解で製造可能な膜も開発されつつある。加えて近年, 燃料電池の固体電解質としてフッ素系スルホン酸ポリマーの適用が期待されており ...

Covalent Organic Frameworks for Photocatalytic CO2 Reduction: Metal Integration Principles, Strategies and Functions

Advanced Functional Materials, EarlyView.
Covalent organic frameworks (COFs) with metals have been recognized as versatile platforms for photocatalytic CO2 reduction (CO2PRR). Herein, an overview of metal integration strategies for COFs is systematically summarized. Regulatory mechanisms and structure–activity relationships between metal integration and COF‐based CO2PRR are emphasized.
