Designing a cost-effective, high potential and recyclable catalyst remains a challenge. In the present work, a monolithic PAM-GO-Ag hydrogel is prepared by a facile, eco-friendly method using gamma-ray irradiation. The formation of GO-Ag composite by gamma radiation is also investigated and it is authenticated by XRD, FTIR, Raman, XPS and TEM analysis. The PAM-GO-Ag hydrogel exhibits excellent catalytic activity to different catalysant like methylene blue, Rhodamine-B, and pharmaceutical compound ciprofloxacin. The high catalyst carrying capacity and rapid electron shuttling ability of GO plays a significant role in the high performance of PAM-GO-Ag hydrogel. The PAM-GO-Ag hydrogel also exhibits excellent antibacterial activity. The damaged cell membrane, protein leakage, and increased ROS level contribute to the antibacterial activity of PAM-GO-Ag. The monolithic structure of PAM-GO-Ag hydrogel makes it easy to handle, recover, and reuse for several runs without significant loss of catalytic and antibacterial activity. All these results showed the possible application of PAM-GO-Ag hydrogel as a promising catalyst for the reduction of different pollutants and antibacterial agents on a large scale with good reusability.

设计具有成本效益，高潜力和可回收利用的催化剂仍然是一个挑战。在目前的工作中，通过使用伽马射线辐射的简便，环保的方法制备了整体式PAM-GO-Ag水凝胶。还研究了由γ辐射形成的GO-Ag复合物，并通过XRD，FTIR，拉曼，XPS和TEM分析对其进行了鉴定。PAM-GO-Ag水凝胶对不同的催化剂（如亚甲基蓝，若丹明-B和药物化合物环丙沙星）表现出出色的催化活性。GO的高催化剂承载能力和快速的电子穿梭能力在PAM-GO-Ag水凝胶的高性能中起着重要作用。PAM-GO-Ag水凝胶还具有出色的抗菌活性。细胞膜受损，蛋白质泄漏，ROS水平的升高有助于PAM-GO-Ag的抗菌活性。PAM-GO-Ag水凝胶的整体结构使其易于处理，回收和重复使用多次，而不会显着降低催化和抗菌活性。所有这些结果表明，PAM-GO-Ag水凝胶有可能作为一种有前途的催化剂用于大规模减少各种污染物和抗菌剂，并具有良好的可重复使用性。
