Summary: Photocatalytic CO2 reduction is a sustainable and inexpensive method to solve the energy crisis and the greenhouse effect. A Bi@Bi2MoO6 photocatalyst with Bi nanoparticles grown on the surface of Bi2MoO6 nanosheets was fabricated, exhibiting great activity due to abundant active sites, effective carrier separation, and localized surface plasmon resonance effect. Addition of NaHCO3 significantly increased C2H5OH generation rate and product selectivity in the system, achieving high formation rates of CO, CH3OH, and C2H5OH in photocatalytic measurement.

Summary: A Bi/Bi2MoO6 nanocomposite with great photodegradation ability to tetracycline (TC) was successfully fabricated through a simple one-pot solvothermal method. The photodegradation of TC was enhanced by the surface plasmonic resonance (SPR) effect, where the light energy was absorbed by Bi-0 nanoparticles and transferred to adjacent Bi2MoO6. The formation of center dot O-2(-) through the reaction of photoelectrons with soluble O-2 and center dot OH was identified as the dominant process in the photocatalytic degradation of TC. This study proposes a highly efficient photocatalyst based on SPR effect, which holds promising application potential in environmental treatment.
