An enormous number of specific case studies have been reported that deal with the removal methodologies customarily employed for the reduction of common aqua-soluble pollutants [particularly nitrophenols (NPs) and nitroaniline (NAs)]. However, reviews that not only organize the literature in some presentable form but also work as a guideline for new scholars looking to exploit the field of nanocatalysis are surprisingly non-existent. Here in, an attempt has been made to comprehensively summarize the basic issues along with an insight to specific contributions devoted to NAs and NPs removal by utilizing the nanomaterial of silver. Furthermore, keeping in mind the significance of the surface functionalization of nanomaterial in catalysis, advantages/disadvantages of several entrapment mediums generally adopted for preventing the aggregation of nanomaterial are also summarized. A generalized overview of the various commonly employed removal practices along with its comparison to the catalytic reductive technique is also presented in the study. Finally, remaining unaddressed problems associated with this field and future directions for engineering cost-efficient and effective nanocatalyst assemblies are discussed in the end.

用于使银纳米材料对苯胺和酚类污染物失效的各种支持介质的批判性分析：综述

大量的具体案例研究已经报道，涉及通常用于减少常见水溶性污染物 [特别是硝基苯酚 (NPs) 和硝基苯胺 (NAs)] 的去除方法。然而，令人惊讶的是，那些不仅以某种可展示的形式组织文献，而且还为寻求利用纳米催化领域的新学者提供指导的评论却令人惊讶地不存在。在此，尝试全面总结基本问题，并深入了解通过利用银纳米材料去除 NAs 和 NPs 的具体贡献。此外，牢记纳米材料表面功能化在催化中的重要性，还总结了通常用于防止纳米材料聚集的几种截留介质的优缺点。研究中还介绍了各种常用去除方法的概括概述及其与催化还原技术的比较。最后，最后讨论了与该领域相关的未解决的问题以及设计具有成本效益和有效的纳米催化剂组件的未来方向。
