A perspective on field-effect in energy and environmental catalysis.

The development of catalytic technologies for sustainable energy conversion is a critical step toward addressing fossil fuel depletion and associated environmental challenges. High-efficiency catalysts are fundamental to advancing these technologies. Recently, field-effect facilitated catalytic processes have emerged as a promising approach in energy and environmental applications, including water splitting, CO reduction, nitrogen reduction, organic electrosynthesis, and biomass recycling.

Oxidation engineering triggered peroxidase-like activity of VOC for detection of dopamine and glutathione.

MXenes, two-dimensional nanomaterials, are gaining traction in catalysis and biomedicine. Yet, their oxidation instability poses significant functional constraints. Gaining insight into this oxidation dynamic is pivotal for designing MXenes with tailored functionalities.

TiC nanosheets with broad-spectrum antioxidant activity for cytoprotection against oxidative stress.

Redox regulation in biological systems represents a fascinating method for treatment and prevention of oxidative stress induced diseases. The key and difficult point is to find ideal materials with excellent antioxidant capability and good biocompatibility. To this end, ultra-thin two-dimensional MXene (TiC) nanosheets (NSs) were investigated for their antioxidant capability.
