    Effective coupling of phenol adsorption and photodegradation at the surface of micro-and mesoporous TiO2-activated carbon materials

    Novel titania supported activated carbon catalysts were prepared by a straightforward titania coating route of a microporous activated carbon (AC) derived from shea nut shells, and investigated in phenol photo...

    Preparation, chemical modification and absorption properties of various phthalocyanines

    A series of phthalocyanines were prepared from phthalodinitrile and corresponding metal salts by means of the ‘solvent’ methods. Some experiments were also conducted in the absence of a solvent in a ‘solvent-f...
