Novel S-scheme heterojunction interface composite (MnMgPO4@C3N4) of bimetallic phosphate MnMgPO4 and C3N4 with different proportions was successfully constructed in this work. The nanosheet surface structure the integration two materials endowed heterojunctions superior visible light absorption improved photogenerated carrier transfer, boosting photocatalytic hydrogen production degradation performance. (5C5MMP) optimal mass ratio (MnMgPO4/C3N4 = 5/5) achieved strongest potency. evolution rate about 3.595 mmol·g−1·h−1, pollutants methylene blue (MB), oxytetracycline (OTC), tetracycline (TE) were almost entirely degraded within 40 min. rates approximately 97.1% 95.4% 99.7% (TE). Notably, displayed exceptional stability structural durability. mechanism revealed that 5C5MMP exhibited photocurrent response, least electron transfer resistance, lowest recombination rate, resulting Furthermore, both MgMnPO4 identified as n-type semiconductors. optimized band photocatalyst enhanced charge separation enabled system to generate more reactive electrons for reduction holes oxidation, significantly accelerating pollutant degradation. By proposing an composite, research offers innovative strategy designing efficient photocatalysts underscores feasibility using composites enhance removal.
