A critical review of industry 5.0-enabled nano-catalysts for synergistic air, water, and soil pollution abatement toward environmental sustainability
AI summary Read the abstract
This review summarizes existing research on tiny nanocatalysts used to clean up pollution in air, water and soil, including microplastics, heavy metals and pharmaceutical residues. It covers 138 studies from 2020 to 2026 and describes new technologies like AI-assisted systems and sensors, while proposing a new method called SMMRI to compare how well different nanocatalysts work, and noting unresolved challenges like scaling up and lifecycle regulations.
Environmental remediation has started to take advantage of all the advantages of Industry 5.0: sustainabililty, resilience and human-centric techologies. The role of nanocatalysts has a privileged part on it, as they allow the remediation of numerous pollutants present in atmosphere, water or soils. On this review we analyze this variety through an extensive list of environmental targets, covering from heavy metals and organic species until microplastics, pharmaceutical residues, and various recalcitrant pollutants. After a PRISMA 2020 guideline-compliant search strategy, on a total database of 1,928 records we detected 196 selected articles and 138 reporting data from 01/2020 till 03/2026, we include a study on single atom and bi-metallic catalysts, on the application of MOF based framework materials, stimuli responsive and hybrid nanocatalysts and analyze innovative application involving artificial intelligence, digital twins, Internet of Things integrated sensors and adaptive process control while identify what has been tested on the lab and what remain as only the “smart idea”. To provide a general approach of the comparison between the performance of class of nanocatalyst toward a determined class of polluter within a determined matrix, we propose the SMMRI (Synergistic Multi-Matrix Remediation Index); a method currently undergoing for further developing that help on understanding existing challenges such as stability of nanocatalysts, ability for scaling-up, generation of secondary particles or issues relating the lifecycle and the regulations.

AI summary Read the abstract
This review pulls together nearly 200 studies on tiny engineered particles called nanocatalysts, which can break down harmful pollutants like heavy metals, microplastics, and drug residues in air, water, and soil. While promising, the technology is still mostly tested in labs, and researchers still need to solve issues like durability and safety before it can clean up real-world environments at scale.

AI summary Read the abstract
This review pulls together nearly 140 studies on tiny engineered particles called nanocatalysts, which can be used to break down harmful pollutants in air, water, and soil, including microplastics and drug residues that regular water treatment often misses. While the technology shows promise in lab settings, the researchers note that big questions remain about whether it's safe and practical at scale, including whether these nanocatalysts might break down into new particles that could pose their own risks. In other words, this cleanup technology could eventually help reduce our exposure to pollutants like microplastics, but it's not ready for real-world use yet.
