CuO-ZnO-La2O3/activated carbon (AC) adsorbent was prepared and used for efficient adsorption removal of PH3 at various temperatures in the presence of O2. The feasibility of water and thermal regeneration of a spent CuO-ZnO-La2O3/AC adsorbent was also investigated. The influences of regeneration temperature, water concentration and calcination time were done on the spent CuO-ZnO-La2O3/AC adsorbent...
Transition metal ion (V, Fe, or Cu) doped TiO2 nanoparticles were synthesized from titanium tetraisopropoxide (TTIP) in absolute ethanol by the modified sol-gel method. The precursor of the transition metal to be doped was added to an alcoholic solution containing TTIP. This solution was loaded into a pouch type cellophane membrane and placed in a clear solution containing 1:1 (v/v) ratio of absolute...
