MXene‐Based Electrocatalysts for Sustainable Nitrogen Conversion: From Ammonia Oxidation to Nitrogen and Nitrate Reduction

2D transition‐metal carbides and nitrides, known as MXenes, have emerged as promising electrocatalysts for nitrogen‐related reactions, including ammonia oxidation (AOR), nitrogen reduction (NRR), and nitrate reduction (NO3RR). Their appeal stems from a layered architecture, abundant active sites, tunable surface chemis...

Tuning Oxygen Vacancy Density in TiO2 Hosts for Stabilizing Nanoscale Pt Species and Enhancing Hydrogen Evolution

Developing efficient electrocatalysts for the hydrogen evolution reaction (HER) with improved noble‐metal utilization is essential for sustainable hydrogen production. Here, defect‐engineered TiO2−x supports were developed to stabilize dispersed Pt nanoparticles (∼5 nm) and regulate metal–support interactions. Oxygen v...
