2D black phosphorus and tungsten trioxide heterojunction for enhancing photocatalytic performance in visible light
A novel, efficient and stable 2D black phosphorus and tungsten trioxide heterojunction (WO 3 -BPNs) was successfully synthesized using a combined hydrothermal, liquid phase exfoliating and co-precipitation method. The as-obtained WO 3 -BPNs composite was characterized by using XRD, SEM, XPS, UV-vis,...

| description | A novel, efficient and stable 2D black phosphorus and tungsten trioxide heterojunction (WO
3
-BPNs) was successfully synthesized using a combined hydrothermal, liquid phase exfoliating and co-precipitation method. The as-obtained WO
3
-BPNs composite was characterized by using XRD, SEM, XPS, UV-vis,
etc.
The results showed that the bandgap energy of the WO
3
-BPNs50 sample was 2.2 eV, which was lower than that of pure WO
3
. BPNs in the WO
3
-BPNs heterojunction as a co-catalyst effectively enhanced photo-generated electron-hole pairs separation. The synthesized WO
3
-BPNs sample significantly improved the photocatalytic performance in degrading rhodamine B (RhB) and metoprolol (MET) compared to pure WO
3
and BPNs under visible-light. The maximum RhB and MET removal efficiencies were 92% and 87%, respectively, in the WO
3
-BPNs50 (added 50 mL BPNs dispersion) sample within 120 minutes. The relevant photocatalysis mechanisms were discussed. In addition, the intermediate products in the MET photodegradation process were investigated by LC-MS technology, and the degradation pathway of MET was proposed.
