Phosphorus-modified cobalt single-atom catalysts loaded on crosslinked carbon nanosheets for efficient alkaline hydrogen evolution reaction

Yucong Huang et al.

Summary: Efficient and low-cost transition metal single-atom catalysts (TMSACs) have gained significant attention for hydrogen evolution reaction (HER) due to their good catalytic activity without noble metals. However, the complex preparation process and insufficient stability have limited their practical applications. In this study, a simple top-down pyrolysis approach was introduced to obtain P-modified Co SACs loaded on the crosslinked defect-rich carbon nanosheets, which exhibited excellent catalytic activity and stability for alkaline HER.

Heteroatom-doped nanomaterials/core-shell nanostructure based electrocatalysts for the oxygen reduction reaction

Saravanan Nagappan et al.

Summary: This review highlights the significance of heteroatom doped core-shell nanostructures (HCSNs) as superior electrocatalysts for the oxygen reduction reaction (ORR), emphasizing how various heteroatom dopants contribute to enhanced ORR performance. Nitrogen doping in different forms of CSNs creates high surface area and reactive active sites for improved ORR efficiency, making them promising for practical applications in ORR electrodes. Additionally, the combination of multiple heteroatom dopants in CSNs shows potential for synthesizing highly efficient ORR electrodes.
