“…17 Commonly used photocatalysts include TiO 2 , 18 ZnO, 19 CeO 2 , 20 and MoS 2 . 21 Previous studies have demonstrated that the heterojunction of BiOBr 22 and carbon nitride (g-C 3 N 4 ) exhibits high photocatalytic activity, 23 a high vacuum level, 24 and a low electron recombination rate. To further enhance the performance of photocatalysts, piezoelectric materials are now being combined with them to construct heterojunctions.…”

The rational design of bifunctional photocatalysts with high adsorption and enrichment characteristics and excellent photocatalytic redox activity is an effective way to address environmental pollution and energy shortage crisis. In this study, cyclophosphazene‐derived porous organic polymer (PCPD) microspheres with P─N linkage are coated with graphene oxide (GO) and loaded with Ag0 nanoparticles (NPs) to prepare covalently bonded xAg‐rGO/PCPD composites. The catalyst with the highest specific surface area (denoted as 2.5Ag‐rGO/PCPD) shows excellent adsorption capacity for fluoroquinolone antibiotics, removing 96.2% of ciprofloxacin (CIP) through adsorption. By applying the catalyst with the best photocatalytic redox activity (denoted as 5Ag‐rGO/PCPD), 82.97% of refractory sulfonamide antibiotics are removed through adsorption‐degradation, and 635.3 µmol g−1 of CO and 162.3 µmol g−1 of CH4 are generated as products of CO2 photoreduction alone. Among the co‐catalytic systems, the highest CO yield of 9.16 µmol g−1 is obtained by coupling CO2 reduction with levofloxacin (LVX) degradation to harness the electron‐donating power of the pollutant molecule. This study is expected to provide useful guidance for the rational design of bifunctional photocatalysts.

Herein, various BiOBr nanostructures are successfully synthesized using a facile solvothermal method. A series of structural and morphological analyses clearly indicate that due to the nucleation protection provided by KOH and the presence of surface‐absorbed hydroxyl groups, BiOBr transforms from nanosheet microspheres to nanopillow aggregations (BNP) and finally to nanoneedle matrix. The open‐porous nanostructure of the BiOBr nanopillows (BNPs), along with their enhanced visible light absorption capacity and the presence of surface hydroxyls, enables them to adsorb nearly 100% of organic dyes, including rhodamine B (RhB), methylene blue, and methyl red. Furthermore, the BNP exhibits remarkable visible light photocatalytic activity, degrading higher concentrations of RhB in ≈20 min.
