Visualizing Composition and Functionality of Porous Catalysts Using Dual-Emissive Fluorescent Nanoprobes.
Article in ACS central science, 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
The performance of heterogeneous catalyst bodies is closely related to the accessibility and properties of their catalytically most active regions. Visualizing and understanding the composition and functionality of these multicomponent hierarchically structured materials is often time-consuming and expensive. To overcome these challenges, fluorescent nanoprobes have been employed to visualize heterogeneous, complex material composition. So far, fluorescence microscopy approaches are limited to the measurement of spatial heterogeneities of only one propertysuch as accessibility or acidityin a single measurement. In this work, we introduce a dual-emissive solution containing carbon dots and porphyrin nanoprobes to simultaneously map different material domains and properties within heterogeneous catalyst particles. We investigated catalyst components (oxides and supports), spray-dried cracking catalysts, and extruded catalysts. The selective adsorption as well as the aggregation of the probes affect their fluorescence emission characteristics, allowing us to identify regions with similar properties and composition. Our multiprobe staining method is a facile approach for high-throughput composition and property mapping of porous materials, including solid catalysts and adsorbents.
