Synthesis of WS2/Zn0.5Cd0.5S Nanoheterostructured Photocatalyst and Its Visible Light Catalytic Performance

A novel molecularly expanded covalent triazine framework heterojunction with significantly enhanced molecular oxygen activation and photocatalysis performance under visible light

“…32,33 However, as a semiconductor with narrow band gap, monomeric WS 2 has the disadvantages of a quick recombination of photogenerated carriers, weak molecular oxygen activation ability and low photodegradation efficiency. 34 Usually, WS 2 is used to build heterojunctions with other semiconductors, which can further increase the efficiency of photogenerated carrier separation and improve photocatalytic capability. In recent years, numerous of WS 2 -based photocatalysts have been designed, including g-C 3 N 4 /WS 2 , 35 WS 2 /MoS 2 , 36 WO 3 /WS 2 and other compounds.…”
