From Waste to Wealth: Covalent Organic Frameworks for Gold Detection and Recovery from Secondary Sources.
Review in ACS applied materials & interfaces, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Gold is a precious element, renowned for its diverse applications in catalysis, biomedicine, and electronics, largely due to its remarkable stability and superior conductivity. However, the escalating global demand and intensive mining activities have prompted a shift toward exploring gold recovery from alternative and secondary sources. Traditional gold recovery techniques, such as hydrometallurgy and cyanidation, are efficient yet notorious for their toxic byproducts, necessitating the pursuit of more sustainable methods. This review explores the potential of covalent organic frameworks (COFs) as cutting-edge materials for gold detection and adsorption. COFs are distinguished by their precise architecture, inherent porosity, and customizable functionalities, rendering them exceptionally suited for the selective capture of gold. First, we present an overview of the fundamental COF gold adsorption mechanisms, including coordination chemistry, hydrogen bonding, electrostatic interactions, and reduction processes. This is followed by examining COF synthesis methods, functionalization techniques, and composite engineering strategies that optimize their stability and adsorption efficiency. The review further highlights recent advancements in the utilization of COFs for gold sensing, recovery from electronic waste, and adsorption at trace concentrations. Finally, we address the current challenges in the application of COFs in this domain and propose future research directions. This comprehensive review serves as an invaluable resource for advancing gold extraction through COF-based materials, ultimately contributing to innovative and sustainable gold recovery practices.
