Abstract

We demonstrate that particle-particle interaction affects the photocatalytic efficiency of colloids. Colloid silicon carbide nanoparticles were examined by varying their size, size distribution, and surface chemistry, and we found that surface moieties show no effect on the individual particles but dramatically affect the collective photocatalytic efficiency of the system.
