| Abstract | Water pollution and energy crisis are two important research subjects awaited to solution. Herein, we propose a strategy of "turning scrap into wealth" to obtain the highly-efficient photocatalyst for hydrogen evolution by recycling of heavy metal ions in wastewater. The novel mesoporous zeolite Beta (mBeta) can be used as adsorbent to remove the heavy metal ions (Le., Cd2+ and/or Zn2+) from wastewater due to its excellent adsorptive performance from the electrostatic affinity, ion-exchange ability and structural channels in zeolite. Subsequently, in-situ sulfuring of the Cd2+ or/and Zn2+ adsorbed mBeta was carried out to obtain highly-efficient photocatalysts. As expected, the sample CdS/ZnS-mBeta exhibited super photocatalytic activity and high stability wider visible light irradiation. It is believed that the synergetic effect between CdS and ZnS nanoparticles are responsible for its good visible light absorption performance and the effective separation of photoelectrons and holes. Besides, the mBeta with high specific surface area can improve the dispersibility of sulfides, which would contribute to its high stability. |
