Abstract
A new photocatalyst for degradation of dye from waste-water using alkali-activated steel slag-based mesoporous material (ASSMM) by adding pore-forming agent was firstly prepared. The XRD results showed that there were mainly mineral phase of calcium silicate hydrate (CSH) and lawsonite, (CaAl2Si2O7(OH)2·H2O) in the ASSMM samples by adding of pore-forming agent. The result of BET specific surface area indicated that more than 85% of pore volume principally centralized on mesoporous range with the pore size diameter of 2-50nm for the sample (0.1ASSMM) by adding of 0.1 wt% pore-forming agent. The degradation rate of malachite green (MG) dye is in the order of 0.1ASSMM > 5ASSMM > 1ASSMM > ASSMM > dye of direct photolysis. The 0.1ASSMM photocatalyst exhibited the highest degradation rate under UV irradiation, and the highest degradation rate can reach 95.53%. The photodegradation belongs to the first-order reaction kinetics.
