Cu/Fe co-doped Sphagnum palustre-derived biochar for the synergistic adsorption and photocatalytic removal of tetracycline hydrochloride.
Article in Journal of advanced research, 2026. 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
introductionThe widespread presence of antibiotic pollutants, such as tetracycline hydrochloride (TCH), causes significant environmental and public health concerns. Biochar-based photocatalysts derived from renewable biomass have attracted increasing attention due to their low cost, structural tunability, and environmental sustainability. However, their photocatalytic performance is often limited by poor charge separation and a lack of active sites.
objectivesThis study aims to construct a visible-light-responsive Cu/Fe co-doped biochar composite using Sphagnum palustre as a biomass precursor for the synergistic adsorption and photocatalytic removal of TCH from aqueous environments.
methodsThe Cu/Fe co-doped photocatalyst (CFO/S) was synthesized via a hydrothermal method by integrating Cu-Fe oxides with Sphagnum-derived biochar. The composite was comprehensively characterized, and its visible-light performance was evaluated. The photocatalytic mechanism was elucidated through radical trapping experiments and DFT+U simulations.
resultsThe CFO/S-10 composite achieved a TCH removal efficiency of 94.56% within 60 min under visible-light irradiation. Adsorption was identified as the primary removal mechanism, while photocatalysis contributed to the degradation of adsorbed molecules. A layered FeO/CuFe
conclusionThe Cu/Fe co-doped biochar composite exhibited excellent removal performance through a synergistic adsorption-photocatalysis mechanism. Photogenerated electrons were the dominant reactive species, supported by •OH, •O
