Antibiotic and bacteria pollutions widely exist in aquatic environment, and pose a great threat to human health. The effective removal of antibiotic and microbial contamination from water is of great importance in global public health. In this study, black melamine-based sponge (AMS) was prepared by calcination method. Tetracycline (TC) and Salmonella were picked as models to investigate the antibiotic degradation and antibacterial property of AMS, and the possible reaction mechanism of AMS photocatalyst in the removal of tetracycline and Salmonella was also investigated. Compared with conventional method for fabricating photocatalyst materials, the current strategy for fabricating AMS is low-cost, rapid, low energy input, easy to operate and does not involve any additional additives. The results indicated that AMS possessed porous structure and obvious visible-light absorption, and exhibited excellent photocatalytic activity with the rate constant of 0.2059 min^-1 for the removal of tetracycline and 98.1% inactivation rate of Salmonella under visible-light irradiation. Moreover, the analysis of various experiment results indicated that the degradation of TC by AMS was mainly attributed to photo-generated radicals, while the destruction of Salmonella was due chiefly to the photothermal conversion performance of AMS. This kind of low-cost and high-efficiency melamine-derived sponge has great potential to degrade antibiotics and destroy bacteria, verifying AMS is a promising water purification photocatalyst.

抗生素和细菌污染广泛存在于水生环境中，对人类健康构成巨大威胁。从水中有效去除抗生素和微生物污染对全球公共卫生至关重要。在这项研究中，通过煅烧方法制备了黑色三聚氰胺基海绵（AMS）。以四环素和沙门氏菌为模型研究AMS的抗生素降解和抗菌性能，以及AMS光催化剂在去除四环素和沙门氏菌中可能的反应机理。还进行了调查。与制造光催化剂材料的传统方法相比，当前制造AMS的策略是低成本，快速，低能量输入，易于操作且不包含任何其他添加剂。结果表明，AMS具有多孔结构，可见光吸收明显，具有良好的光催化活性，可见光下四环素的去除速率常数为0.2059 min ^-1，沙门氏菌灭活率为98.1％。此外，对各种实验结果的分析表明，AMS对TC的降解主要归因于光生自由基，而沙门氏菌的破坏主要是由于AMS的光热转换性能。这种低成本，高效率的三聚氰胺衍生海绵具有降解抗生素和消灭细菌的巨大潜力，证明AMS是一种有前途的净水光催化剂。
