Hybrid Carbon Nitride/Cobalt Phthalocyanine Nanocomposites for Efficient Photocatalytic Hydrogen Generation.
Article in ACS applied energy materials, 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 photocatalytic production of hydrogen stands out as a promising strategy to convert and store solar energy as chemical energy in the form of a sustainable energy carrier. In the present study, a hybrid photocatalyst based on cobalt phthalocyanine (CoPc) coupled with polymeric carbon nitride (CN) is synthesized using a simple, cost-effective, and upscalable method. Both components are held together in the hybrid nanocomposite via π-π interactions, as shown by detailed structural and optical characterization. The synergistic interaction between both components, CN, a metal-free semiconductor, valued for its stability and tunable electronic properties, and CoPc, known for its excellent light absorption and electronic properties, is evidenced in a proof-of-concept photocatalytic reaction: the photo-oxidation of benzyl alcohol (BzOH) to benzaldehyde (BzO). Chemical trapping reagents were employed to elucidate the reaction mechanism, showing favorable recombination dynamics of the hybrid photocatalyst (CoPc/CN) compared to the individual components. Furthermore, photocatalytic hydrogen production was conducted in an aqueous solution using triethanolamine (TEOA) as an electron donor, with the optimized CoPc/CN nanocomposite producing 1136.5 μmol h
