Single-atom catalysts are a family of heterogeneous electrocatalysts widely used in energy storage and conversion. The determination the local structure active metal sites is challenging, which limits establishment reliable structure-property relationship single-atom catalysts. A carbon black-conjugated complex can be as model catalyst to probe intrinsic activity with certain structures. In thi...

Although carbon-supported platinum (Pt/C) has been generally used as a catalyst for the oxygen reduction reaction (ORR) in fuel cells, its practical application is limited by corrosion of carbon support. Therefore, it essential to develop new self-supported catalysts ORR. Noble metal aerogels represent highly promising with large specific surface area and excellent electrocatalytic activity. Cl...

Rational design of hierarchically structured electrocatalysts is particularly important for electrocatalytic oxygen reduction reaction (ORR). Here, ZIF-67 crystals are stringed on core–shell [email protected] nanocables using a coordination-modulated process. Upon pyrolysis, strings Co nanoparticles embedded with three-dimensional porous carbon beads-on-string hierarchical structures developed....
