A terephthalic acid functionalized g − C₃N₄ (TACN) was newly developed and utilized in the development of visible–light–driven magnetically recyclable TACN/TiO₂/Fe₃O₄@SiO₂ (TTFS) Z–scheme heterojunction nanophotocatalyst. The characterization was performed by BET surface area analyzer, TEM, UV–vis DRS, VSM, XRD, and XPS. To ensure its practical applicability, the experiments were also performed for real sewage effluent spiked with pharmaceuticals and personal care products (PPCPs) in which degradation of 97% of the 2 mg L^-1 of ibuprofen in 120 min, 94% of the 2 mg L^-1 of benzophenone–3 in 150 min, and 94% of the 2 mg L^-1 of carbamazepine in 240 min was achieved upon 330 W m^-2 of integrated visible light irradiance. The recycling of the TTFS nanophotocatalyst was achieved without adopting calcination or heating within a short contact time (5 h), maintaining a photocatalytic efficiency of over 83% after 5 cycles, which proves its potential for real practical applications.

对苯二甲酸功能化的g-C ₃ N ₄（TACN）是新开发的，并用于可见光驱动的可磁循环利用的TACN / TiO ₂ / Fe ₃ O ₄ @SiO ₂（TTFS）Z方案异质结纳米光催化剂的开发中。通过BET表面积分析仪，TEM，UV-vis DRS，VSM，XRD和XPS进行表征。为确保其实际适用性，还对掺有药品和个人护理产品（PPCP）的实际污水进行了实验，其中120 mg的布洛芬2 mg L ^-1降解97％，2 mg的94％降解在150分钟内产生L ^-1的二苯甲酮–3，以及2 mg L中的94％330 W m ^-2的集成可见光辐照度在240分钟内达到^-1的卡马西平。TTFS纳米光催化剂的回收利用在短时间内（5小时）内无需进行煅烧或加热，而在5个循环后仍保持了83％以上的光催化效率，这证明了其在实际应用中的潜力。
