In a study published in Nature (« Functional CeOx nanoglues for robust atomically dispersed catalysts »), a research team led by Prof. ZENG Jie from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences and international collaborators developed a novel “nanoglue” strategy to stabilize atomically dispersed metal catalysts.

The main characteristic of Spark Plasma Sintering (SPS) is that the pulsed or unpulsed DC or AC current directly passes through the graphite die, as well as the powder compact, in case of conductive samples. Joule heating has been found to play a dominant role in the densification of powder compacts, which results in achieving near theoretical density at lower sintering temperature compared to conventional sintering techniques.
