Abstract The rational design of bifunctional photocatalysts with high adsorption and enrichment characteristics excellent photocatalytic redox activity is an effective way to address environmental pollution energy shortage crisis. In this study, cyclophosphazene‐derived porous organic polymer (PCPD) microspheres P─N linkage are coated graphene oxide (GO) loaded Ag 0 nanoparticles (NPs) prepare covalently bonded xAg‐rGO/PCPD composites. catalyst the highest specific surface area (denoted as 2.5Ag‐rGO/PCPD) shows capacity for fluoroquinolone antibiotics, removing 96.2% ciprofloxacin (CIP) through adsorption. By applying best 5Ag‐rGO/PCPD), 82.97% refractory sulfonamide antibiotics removed adsorption‐degradation, 635.3 µmol g −1 CO 162.3 CH 4 generated products 2 photoreduction alone. Among co‐catalytic systems, yield 9.16 obtained by coupling reduction levofloxacin (LVX) degradation harness electron‐donating power pollutant molecule.

Engineering a ZnO/Ag₂CO₃/Ag₂O Ternary Heterojunction: Dual Z-Scheme Photocatalytic Pathway for Enhanced Pollutants Degradation

Langmuir, Journal Year: 2025, Volume and Issue: unknown

Published: April 9, 2025

As the widespread discharge of antibiotics, pesticides, and dyes exacerbates water pollution, development efficient photocatalytic materials has become crucial for addressing this challenge. In study, a new paradigm n-p-p ternary heterojunction photocatalyst composed ZnO nanospindle, Ag2CO3, Ag2O nanoparticles was synthesized via hydrothermal coprecipitation method followed by calcination. By adjusting calcination time, phase transition from Ag2CO3 to precisely controlled, leading enhanced charge separation, transition, improved light absorption properties. The prepared ZnO/Ag2CO3/Ag2O (Z/AC/A) exhibited outstanding performance degradation typical pollutants, including 2,4-dichlorophenol (2,4-D), tetracycline (TC), malachite green (MG) under simulated sunlight irradiation. And efficiencies reached 90.8, 94.8, 97.4%, respectively, with photocatalyst, which calcined at 195 °C 12 min, abbreviated as Z/AC/A-3, demonstrating highest activity. Radical scavenging experiments electron spin resonance (ESR) tests revealed that superoxide radicals (•O2-) serve dominant active species, while holes (h+) hydroxyl (•OH) play secondary roles in process. Additionally, mechanism confirmed follow dual Z-scheme transfer pathway, effectively separation performance. also excellent structural stability reusability over five consecutive cycles. These results suggest Z/AC/A holds promising potential practical applications environmental remediation.
