Abstract

A series of nitrogen-doped SrMoO4 with different Sr/N mole ratio (R=0, 0.05, 0.10, 0.15, 0.20, 0.40, and 0.60) were synthesized using urea as the N source via the vapor-thermal method. The photocatalytic degradation ability of all samples was evaluated using methylene blue (MB) as a target contaminant. The band gaps of N-doped samples are all higher than that of pristine ones, which is only 3.12 eV. BET specific surface area SBET and pore volume are increased due to the N doping. And the greater increase of SBET, the faster the photodegradation speed of methylene blue on SrMoO4. More specifically, the degradation efficiency of MB is improved up to 87% in 100 min.
