In situ ligand-modulated activation of inert Ce(III/IV) into ozonation catalyst for efficient water treatment.

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
As a classic strategy to maximize catalytic activity, modulation of the electronic structure of central metal using organic ligands encounters great challenge in radical reactions exemplified by advanced oxidation processes (AOPs) due to operando destruction of employed ligands. Herein, we provide a paradigm achieving in situ ligand-modulated activation of the originally inert Ce(III/IV) for catalytic ozonation as a representative AOP widely applied in full-scale water treatment. Among the small-molecule carboxylates typically produced from pollutant degradation during ozonation, we find oxalate (OA) is a potent ligand to activate Ce(III/IV), inducing 11.5- and 5.8-fold elevation in rate constants of O
