There is a need for methods that make it possible to identify compound structures based on their MS and MS/MS information and quantify them without analytical standards. Method refinements that utilize machine learning algorithms and chemical descriptors to estimate the instrument response of particular compounds have made progress in recent years. This narrative review seeks to summarize the current state of the field of NTA toward quantification of unknowns without the use of analytical standards.

In this regard, synthesising these catalysts from waste material could be a judicious alternative with multiple environmental and economic benefits. Already in H-EF systems, nitrogen-containing porous biochar has exhibited exceptional H<sub>2</sub>O<sub>2</sub> selectivity replacing conventional carbon catalysts, while metallic scraps have been efficiently repurposed to substitute the virgin metal components of heterogenous catalysts. In addition, life cycle assessments have affirmed that repurposed waste catalysts can substantially lower the adverse environmental impacts of H-EF systems.

Their persistence, bioaccumulation, and toxicity, even at low concentrations, represent a major environmental and human health concern. So far, diverse degradation treatment processes have been explored; enzyme-assisted methodologies have been recognized as greener, safer, less expensive, and eco-friendly alternatives. However, the limited reusability and instability of natural enzymes under typical harsh environmental conditions significantly hinder applicability. Thus, different strategies have emerged, such as the design of engineered modified enzymes, the immobilization of enzymes on nanomaterials, and the development of artificial enzymes. Nanomaterials with enzyme-like activities have emerged as artificial enzymatic tools that catalytically degrade toxic pollutants. Recent studies have reported excellent performances of enzymes in the removal of emerging contaminants. This review thoroughly examines the most recent developments in the use of nanozymes for the remediation of various aquatic matrices.
