Abstract

fetched live from OpenAlex

Abstract A complex nanoarchitecture composed of TiO 2 nanobelts, graphite‐like carbon, and Au nanoparticles (NPs) is developed using an in situ surface polymeric encapsulation technique. The precise arrangement of the carbon layer and Au NPs on a TiO 2 surface can be programmed to form three different core@shell structures by simply varying the addition sequence of materials during the encapsulation process. The photocatalytic activity of the three nanoarchitectures is assessed in H 2 generation, degradation of dye molecules as well as photoelectrochemical cells under solar and visible light irradiation. In the reaction of H 2 generation, no activity can be detected for all samples under visible‐light, while under solar light the sample with Au on the surface of carbon layers wrapped on TiO 2 shows the highest activity. By stark contrast, in the photodegradation test, significant difference in activity under visible light is observed, where the sample with Au NPs sandwiched between carbon layers demonstrates the highest activity. All the results indicate that the synergistic effect of carbon‐layers and Au NPs is essential for the catalytic activity enhancement. Moreover, the activity of the photocatalysts is not only highly dependent on the architecture of the catalyst, but also on the type of reaction investigated.

Not 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.
