Defects in Carbon-Based Materials for Electrocatalysis: Synthesis, Recognition, and Advances

Yi Jia et al.

Summary: Due to climate change and over-reliance on fossil fuels, the study and development of sustainable energy is of essential importance. Rapid advances have been witnessed in various power to gas electrocatalysis technologies, but practical applications are limited by expensive electrode materials. Therefore, developing cost-effective electrocatalysts with high performance is significant for the commercialization of green hydrogen technology.

Catalysts by pyrolysis: Direct observation of transformations during re-pyrolysis of transition metal-nitrogen-carbon materials leading to state-of-the-art platinum group metal-free electrocatalyst

Yechuan Chen et al.

Summary: Transition metal-nitrogen-carbon (M-N-C) materials are promising candidates for energy technology and decarbonization. A secondary heat treatment process, called re-pyrolysis, improves the properties and stability of M-N-C materials. This process leads to the partial amorphization of the carbonaceous substrate and optimization of the material's morphology and association with transition metals.

Identification of durable and non-durable FeNx sites in Fe-N-C materials for proton exchange membrane fuel cells

Jingkun Li et al.

Summary: Fe-N-C materials show promise as an alternative to platinum in acidic polymer fuel cells, but limited understanding of their operando degradation hinders rational approaches to improved durability. Two distinct FeNx sites in the catalysts degrade differently during the oxygen reduction reaction, with one site substantially contributing after 50 hours of operation.

Vaporized-salt-induced sp3-hybridized defects on nitrogen-doped carbon surface towards oxygen reduction reaction

Yuanjie Cao et al.

Summary: A method utilizing vaporized salt to introduce abundant sp(3)-hybridized carbon defects on N-doped carbon surface has been proposed, resulting in enhanced electrocatalytic performance for oxygen reduction reaction. The increased sp(3)-hybridized carbon defects were found to be responsible for the improvement in ORR activity. This method shows universality and significance in synthesis of defect-rich carbon-based materials.
