Nanoarchitectonics of S‐Scheme Heterojunction Photocatalysts: A Nanohouse Design Improves Photocatalytic Nitrate Reduction to Ammonia Performance

Angewandte Chemie International Edition, Journal Year: 2024, Volume and Issue: 63(38)

Published: June 25, 2024

Photocatalytic nitrate reduction reaction (NitRR) is a promising route for environment remediation and sustainable ammonia synthesis. To design efficient photocatalysts, the recently emerged nanoarchitectonics approach holds great promise. Here, we report nanohouse-like S-scheme heterjunction photocatalyst with high photocatalytic NitRR performance. The nano-house has floor of plate-like metal organic framework-based (NH

Metal-organic frameworks as thermocatalysts for hydrogen peroxide generation and environmental antibacterial applications

Science Advances, Journal Year: 2025, Volume and Issue: 11(2)

Published: Jan. 8, 2025

Reactive oxygen species (ROS) are highly reactive, making them useful for environmental and health applications. Traditionally, photocatalysts piezocatalysts have been used to generate ROS, but their utilization is limited by various physical constraints. This study introduces metal-organic frameworks (MOFs) as modern thermocatalysts efficiently producing hydrogen peroxide (H 2 O ) from small temperature differences. Temperature fluctuations, abundant in daily life, offer tremendous potential practical thermocatalytic As proof of concept, MOF materials coated onto carbon fiber fabric (MOF@CFF) created a antibacterial filter. The compared three different MOFs (CuBDC, MOF-303, ZIF-8) with bismuth telluride (Bi Te 3 ), known material. ZIF-8 demonstrated superior H generation under low-temperature differences, achieving 96% activity through variation cycles. work advances thermoelectric applications MOFs, enabling real-time purification disinfection generation. findings open interdisciplinary avenues leveraging effects catalysis technologies.

Novel A–D–A Type Naphthalenediimide Supramolecule for H₂O₂ Photosynthesis with Solar‐to‐Chemical Conversion 1.03%

Advanced Energy Materials, Journal Year: 2024, Volume and Issue: 14(30)

Published: May 17, 2024

Abstract Organic supermolecules have shown great promise for photocatalytic hydrogen peroxide (H 2 O ) production. However, the limitation of intramolecular charge separation efficiency is still a crucial scientific problem. In this study, novel acceptor–donor–acceptor (A–D–A) type naphthalenediimide supramolecule (SA‐NDI) successfully designed overcoming fundamental issues in organic supermolecule. Composed one electron‐rich core (naphthalenediimide) and two electron‐poor units (aminopyridine), possesses strong transfer ability. Meanwhile, SA‐NDI has an obviously stronger internal electric field, which 2.83 times higher than that D–A supramolecule. The A–D–A efficiently accelerates separation, so electron quickly migrates to acceptor two‐electron oxygen reduction reaction. shows excellent H accumulation ability (13.7 m stable cyclic time above 120 h. catalyst exhibits superior solar‐to‐chemical conversion 1.03% under simulated solar irradiation. This work provides entirely new idea design with efficient monomer.
