Macroporous particle photocatalysts can be produced using polystyrene latex (PSL) colloidal templating (see figure), which can be used for organic waste degradation. The rate of degradation is similar to that of nanoparticles. Macroporous particles have lower mechanical mobilities than nanoparticles and can be easily collected and recovered for repeated use.
