In recent years, the excessive use and improper disposal of antibiotics have led to their pervasive presence in environment, resulting significant antibiotic pollution. To address this pressing issue, present study synthesized nickel–iron-layered double hydroxides (NiFe-LDHs) with varying molar ratios using a hydrothermal method, employing these LDHs as catalysts for oxidative degradation doxycycline, peroxymonosulfate (PMS) serving oxidant. X-ray diffraction analysis confirmed that NiFe-LDHs exhibited hexagonal crystal structure characteristic layered hydroxides. Experimental results demonstrated catalytic efficiency increased both dosage catalyst concentration PMS, achieving high doxycycline at 0.5 g/L. Furthermore, performance was notably effective across range pH conditions, highest being observed Ni–Fe ratio 3:1. The activation PMS by pollutants primarily occurs through singlet oxygen (1O2), superoxide radicals (O2−·), sulfate (SO4−·). also proposed three potential pathways indicating final products lower environmental toxicity. This research offers novel approaches methodologies treatment antibiotic-contaminated wastewater.

China is a significant global producer and consumer of pesticides antibiotics, with their excessive use leading to substantial water pollution that poses challenges for subsequent treatment. Photocatalytic degradation, leveraging renewable solar energy, presents an effective approach decomposing organic pollutants reducing residual contaminant levels in bodies. This represents one way addressing environmental challenges. paper classifies representative photocatalytic materials by structural design degradation principles including MOFs (Metal–Organic Frameworks), metal- nonmetal-doped, mesoporous material-loaded, carbon quantum dot-modified, floatation-based, heterojunction photocatalysts. We also discuss research on pathways reaction mechanisms antibiotics. Of particular importance are several key factors influencing efficiency, which summarized within this work. These include the separation charge transfer rate catalyst surface carriers, wide-spectrum response capabilities photocatalysts, as well persulfate activation efficiency. Furthermore, emphasis placed role played intrinsic driving forces such built-in electric fields catalytic systems. Moreover, introduces promising composite-structure technologies from both perspectives (e.g., Aerogel-based composites) composite-method molecularly imprinted synthesis method). latest development status, along future prospects, presenting valuable insights pollutant targets. work aims facilitate efficient materials, while providing theoretical references governance technologies.
