Abstract
To enhance the recyclability and operability of graphene oxide/TiO2–Bi2O3 (GO–T–B) hybrids photocatalyst in water solution, we studied its photocatalytic activity for degradation of organics pollution and removal of NO gas, respectively, by using the fabricated GO–T–B hybrid coatings. Experimental results showed that the GO–T–B hybrid coating exhibited better photocatalytic activity for RhB and MO than P25 coating, as well as an excellent photocatalytic activity for NO gas, where the removal ratio of NO gas reaches 78.5 % within 60 min. The nanoparticles coating is a simple and valid method to improve the recyclability of nanoparticles. The resultant GO–T–B hybrid coating has great potential for the applications of sewage treatment and air cleaning.
