Sintering of nanoparticles is one of the main causes of their catalytic deactivation. Rational design of nanocatalysts that are stable against sintering is a grand challenge in heterogenous catalysis. Hu et al . present kinetic theories for two competing sintering mechanisms, Ostwald ripening and pa...
