Bismuth oxychloride-based materials for the removal of organic pollutants in wastewater.

Monoclinic scheelite bismuth vanadate (mBiVO4) has gradually been in the limelight in recent years because of its great potential in energy conversion and environmental remediation. However, the ra...

Dual defects and build-in electric field mediated direct Z-scheme W18O49/g-C3N4−x heterojunction for photocatalytic NO removal and organic pollutant degradation

Bi/BiOCl/Bi 2 O 2 CO 3 heterojunction was prepared via one-step hydrothermal process under the synergistic catalysis of Ni 2+ , where Bi(NO 3 ) 3 was employed as Bi source, DMF was used as carbon source and reductant, NiCl 2 was adopted as Cl source and co-catalyst. The content of Bi, BiOCl and Bi 2 O 2 CO 3 can be adjusted by changing the reaction time, temperature, content of DMF and NiCl 2 . The doping of Bi enhanced the photocatalytic activity of BiOCl/Bi 2 O 2 CO 3 under visible-light. Bi/BiOCl/Bi 2 O 2 CO 3 presented photo-degradation activity for environmental pollutants of rhodamine B, sunset yellow and tetracycline, which were 13.01, 9.40, 1.50 times and 168.38, 10.90, 4.75 times higher than BiOCl and Bi 2 O 2 CO 3 , respectively. The improved photocatalytic activity was ascribed to the sensitized effect of Bi and BiOCl, the surface plasmon resonance effect and the heterojunction structure, which inhibited the recombination of photogenerated electron-hole pairs. The degradation mechanism for rhodamine B was discussed, and the decreased toxicity of the degradation products was demonstrated. • The novel Bi/BiOCl/Bi 2 O 2 CO 3 catalyst was synthesized by one-pot hydrothermal method. • Ni 2+ can catalyze the reduction reaction of Bi 3+ by DMF. • Bi/BiOCl/Bi 2 O 2 CO 3 presents enhanced photocatalytic activity for organic pollutants degradation. • 1 O 2 ,·O 2 - and h + play important functions in the photocatalytic process. • The reduced toxicity of the degradation products was testified with culture mung bean sprouts.
