Precise synthesis of targeted noble metal-based high-entropy alloy nanomaterials.
Article in Science advances, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Noble metal-based high-entropy alloys (NM-HEAs) are promising catalysts because of their diverse compositions and complex surface structures, although understanding their formation and achieving precise atomic control remain challenging. Our team introduces a cost-effective synthesis method combining spray drying and thermal decomposition-reduction to produce HEA three-dimensional nanoframeworks (HEA-3DNFs) from quinary to octonary compositions, including Pt-, Ir-, Ru-, and PtRu-based HEAs. Mild heating in H2 facilitates simultaneous reduction of multiple elements, forming single-phase solid solution alloys. The PtNiCoCuRuIr HEA-3DNF exhibits superior methanol oxidation reaction performance (2637 milliamperes per milligram Pt), 15 times higher than commercial Pt black. Noble metals (Pt, Ru, and Ir) lower activation energy for reducing transition metals (Ni, Co, Cu, and Fe). In situ scanning transmission electron microscopy and density function theory calculations reveal phase transformation from a Pt-based face-centered cubic to Ru-based hexagonal close-packed structure, with control over phase composition by adjusting reduction temperatures and Pt-to-Ru ratios. These findings offer insights for developing high-performance and tunable NM-HEA catalysts.
