DESCRIPTION
The sintering phenomenon or thermal deactivation of supported nanoparticles results in loss of active surface area, leading to their performance degradation affecting catalysis reactions. Scientists have proposed two mechanisms for sintering nanoparticles: particle migration and coalescence and Ostwald ripening.
