摘要	The Fenton-like process is a highly efficient and widely applied advanced oxidation technology for degrading organic pollutants under dark conditions. However, its development is limited by low H2O2 utilization, incomplete mineralization, and limited optimal pH range. We developed a CoAl-LDH/porous g-C3N4 catalyst via high-temperature thermal polymerization with NH4HCO3 as a dynamic gas template and urea as a precursor. The reaction rate constant of CoAl-LDH/porous g-C3N4-H2O2 system for degradation of Rhodamine B is 0.0199 min-1, which is about 1.58 times that of the CoAl-LDH-H2O2 system. Moreover, the catalyst sustained performance over four cycles and maintained high activity in degrading three different substrates. The high catalytic activity is attributed to the rich porous structure of g-C3N4, the presence of abundant active sites, and the synergistic interaction between the CoAl-LDH and g-C3N4, which promotes the generation of center dot OH, 1O2, center dot O2-, facilitating pollutant degradation. This study highlights the potential of this CoAl-LDH/porous g-C3N4-based Fenton-like system for applications in dye wastewater treatment.
