The present invention discloses a BiOCl photocatalyst with a super degradation effect. BiOCl is prepared into a special micro-nano ellipsoid structure which significantly improves catalysis efficiency under visible light. With the present invention, degradation rates with gas phase formaldehyde, Congo red solution and hexavalent chromium solution can reach above 90%. Moreover, due to a stable structure, the BiOCl photocatalyst has desired reusability which enables a lower cost of the photocatalyst and wider use in the field of environmental pollution treatment. |
