Surface activated natural wood biomass electrode for efficient microbial electrocatalysis: Performance and mechanism
Bibliographic record
Abstract
Microbial electrocatalysis showed great potential for waste energy harvesting and CO2 upgrading. The conventional electrodes with three-dimensional (3D) architectures hold promise for efficient microbial electrocatalysis, but they were designed as macroporous structure with microfibers in all three dimensions, which could not concurrently improve the mass transfer and microbes penetration. In this study, a high-performance 3D electrode assembled from bulk two-dimensional (2D) structures derived from natural wood was fabricated by hydrothermal treatment for surface activation and followed by pyrolysis. This 2D/3D hybrid structure guaranteed high surface area and multi-transportation-pathways, which endowed the wood electrode attracted more bacterial cells, facilitated the interfacial electron transfer between cells and electrode. As a result, the wood electrode delivered 8.3 times higher power output (483 vs 52 mW/m2) and 3.1 times higher formic acid production (3.3 vs 0.8 mM) than conventional carbon cloth electrode in microbial electrocatalysis system. This work provided new strategy for high-performance wood electrode fabrication and unveiled the mechanism of microbial electrocatalysis with natural biomass electrode.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
