Tin Oxide‐Anchored MXene Composites for Enhanced Hydrogen Evolution in Alkaline Media

Advanced Materials Interfaces, EarlyView.
The schematic illustrates a SnO2/MXene heterostructure for efficient hydrogen evolution. SnO2 nanoparticles are uniformly anchored on conductive MXene nanosheets, enhancing charge transfer and catalytic activity. The MXene substrate provides high electrical conductivity and abundant active sites, while SnO2 facilitates water adsorption and dissociation.

Copper-Modified Titania-Based Photocatalysts for the Efficient Hydrogen Production under UV and Visible Light from Aqueous Solutions of Glycerol

Nanomaterials, 2022
In this study, we have proposed titania-based photocatalysts modified with copper compounds for hydrogen evolution. Thermal pre-treatment of commercial TiO2 Degussa P25 (DTiO2) and Hombifine N (HTiO2) in the range from 600 to 800 °C was carried out ...

Photonic Time Crystals and Time‐Varying Electromagnetic Metamatter: A New Direction for Ultrafast Tunable Photonic and Microwave Materials and Devices

Advanced Science, EarlyView.
Photonic time crystals (PTCs) are systems in which electromagnetic parameters are modulated periodically in time, producing momentum bandgaps via temporal scattering rather than spatial Bragg processes. This review examines the theoretical frameworks, modeling, and computational tools for time‐varying media, and summarizes experimental demonstrations ...

Synergistic Modulation of Ru–O Bond Covalency via Ba/Fe Co‐Doping and Oxygen‐Vacancy Engineering for Efficient Wide‐pH Oxygen Evolution

Advanced Science, EarlyView.
Ba/Fe co‐doping and oxygen vacancy engineering synergistically modulate the Ru–O bond covalency in RuO2, leading to markedly enhanced OER activity across wide‐pH electrolytes. ABSTRACT Developing efficient and stable oxygen evolution reaction (OER) catalysts across a wide‐pH range is critical for practical water electrolysis.
