Abstract

fetched live from OpenAlex

The global energy crisis and environmental challenges necessitate the development of sustainable chemical processes powered by renewable energy sources. In this regard, semiconductor‐based heterogeneous photocatalysis presents a promising strategy to achieving chemical transformation in a greener and more sustainable manner. This review examines the fundamental characteristics and evolving roles of semiconductor‐based heterogeneous photocatalysts, with a particular focus on gallium nitride. Gallium nitride has attracted significant attention due to its intrinsic properties, such as a wide band gap, high electron mobility, and robust stability, which make it particularly suitable for catalytic applications. This review first provides a comprehensive overview of the fundamental principles and key design strategies in semiconductor photocatalysis. It then critically discusses recent advances in gallium nitride‐based photocatalysts. Together, these insights underscore the critical design considerations inherent to semiconductor photocatalysis and illustrate why gallium nitride‐based materials are increasingly viewed as pivotal tools in enabling environmentally friendly and sustainable chemical reactions.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
