Abstract

fetched live from OpenAlex

Heterogeneous supported metal nanoparticles (NPs) are extensively applied in a variety of chemical and energy conversion processes. Traditionally, these catalysts are prepared by deposition methods. However, they usually show wide ranging size distributions and are easily subject to poisoning and coarsening or agglomeration during the reactions. Alternatively, the time and cost-effective in situ exsolution strategy has successfully addressed the above drawbacks and is able to produce finer and more evenly distributed metal NPs even at relatively low metal loading. Endowed by their socketed nature, the exsolved metal NPs possess excellent operational stabilities as well as great catalytic activities. Moreover, these exsolved metal NPs are smart and can be regenerated upon redox treatments, further extending the lifetime of catalysts. This review presents a general idea in facilitating the degree of exsolution from various oxide substrates by summarizing the recent advances in the exsolution related studies and research outputs with a special emphasis on the understanding of the thermodynamical roles of different experimental parameters.

Teacher imitation

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.
