Article Synopsis
- Ammonia is seen as a promising hydrogen carrier due to its efficiency, easier storage, and established infrastructure, allowing for on-demand hydrogen generation via electrochemical ammonia oxidation.
- The study investigates bimetallic PtRh alloy catalysts, which show improved performance in the ammonia oxidation reaction (AOR) compared to standard platinum catalysts, indicating lower energy requirements and better activity.
- X-ray photoelectron spectroscopy reveals that the Rh component modifies the electronic properties of Pt, reducing issues with catalyst poisoning, thereby enhancing the understanding of AOR mechanisms for future catalyst design.
Neuromorphic computing is an emerging area with prospects to break the energy efficiency bottleneck of artificial intelligence (AI). A crucial challenge for neuromorphic computing is understanding the working principles of artificial synaptic devices. As an emerging class of synaptic devices, organic electrochemical transistors (OECTs) have attracted significant interest due to ultralow voltage operation, analog conductance tuning, mechanical flexibility, and biocompatibility.
