Efficient degradation of methylene blue over boron-doped g-C3N4/Zn0.8Cd0.2S photocatalysts under simulated solar irradiation

Abstract

Boron-doped g-C₃N₄/Zn_0.8Cd_0.2S (BCN/ZS) has been prepared through a facile two-pot method and acted as an efficient photocatalysis material for degradation of methylene blue (MB) exposed to the Xe lamp. Construction of the ZS solid solution and BCN graphite-like structure, boron introduction into carbon sites in CN framework and formation of the hybrid structure between BCN and ZS are fully confirmed via various physical and chemical techniques. The last two structural factors are closely related to the enhanced photocatalytic function of the hybrids. Moreover, h⁺ and ˙O₂⁻ are testified as the major reactive species in MB photodegradation. Finally, the possible reaction path was proposed.
