Insights into catalytic activity and selectivity of 5-Hydroxymethylfurfural oxidation on gold single-crystal electrodes.
Article in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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 selective electrochemical oxidation of 5-hydroxymethylfurfural (HMF) to 2,5-furandicarboxylic acid (FDCA) holds transformative potential for advancing sustainable, bio-based polymer production. In this study, we unveil the pivotal role of gold single-crystal electrode surface orientation in directing HMF oxidation pathways under alkaline conditions. Using cyclic voltammetry, we systematically evaluate the oxidation behavior on Au(111), Au(100), Au(110), Au(311), Au(331), and Au(210) surfaces. Our findings reveal that Au(111) and Au(100) surfaces exhibit superior catalytic activity for the complete oxidation to FDCA, while Au(110) promotes the selective formation of 5-hydroxymethyl-2-furancarboxylic acid (HMFCA). These differences in activity are closely linked to the crystallographic structure, influencing adsorption energies and reaction intermediates. In situ infrared reflection absorption spectroscopy (IRRAS) and attenuated total reflectance (ATR) spectroscopy provide direct molecular insights, identifying distinct vibrational signatures of intermediates and products. This study highlights the critical role of electrode surface structure in tuning reaction efficiency and selectivity, contributing to the development of more efficient catalytic processes in green chemistry.
