Preparation, characterization and photocatalytic activity of novel CeO2 loaded porous alkali-activated steel slag-based binding material

Abstract In the present study, CeO 2 loaded porous alkali-activated steel slag-based photocatalyst (CeO 2 -PASSP) as a new catalyst for photocatalytic water-splitting of hydrogen production was prepared via impregnation method. The BET result showed that adding pore-forming agent changed the pore structure of the alkali-activated steel slag-based binding material and the mesoporous volume of photocatalyst carrier increased by 70%. The XRD, TEM and HRTEM results indicated that calcium silicate hydrate was mainly mineral phase in the alkali-activated steel slag-based binding material. CeO 2 nanoparticles with particle size about 10 nm were highly dispersed on the surface of photocatalyst carrier. The photocatalyst loaded 8 wt% CeO 2 showed the weakest photoluminescence intensity. 8CeO 2 -PASSP sample exhibited the highest photocatalytic hydrogen production activity (68.64 mmol/g) and hydrogen generation rate (13.73 mmol/(g⋅h)) in the simulated solar light irradiation for 5 h, and was quite stable after exposure to photocatalytic hydrogen production for a long time. The excellent activity of hydrogen production for 8CeO 2 -PASSP specimen was ascribed to the co-action of the high S BET , large mesoporous volume and the active components of the CeO 2 and FeO existed in photocatalyst carrier.
