Photodegradation of 2-chlorophenol over colloidal -FeOOH supported mesostructured silica nanoparticles: Influence of a pore expander and reaction optimization (vol 149, pg 55, 2015)

•Colloidal metal was immobilized onto different locations of a modified support.•Colloid structure of iron was retained after loading onto various silica supports.•Location of the colloidal metal on support is important for 2-chlorophenol removal.•Adsorption of the pollutant did not enhance 2-chlorophenol photodegradation.
