Abstract
Abstract The critical challenges of the energy crisis and environmental degradation promote innovative approaches for energy conversion. Semiconductor‐based photocatalytic technology, which transforms solar energy into chemical energy, emerges as a promising solution. However, the practical application of this technology faces several challenges, such as the rapid recombination of photogenerated electrons and holes, significantly limiting photocatalytic efficiency. In this review, we provide a detailed discussion, an insightful perspective, and a critical evaluation of recent advances, challenges, and opportunities in the field of photocatalysis using polar materials. We present a comprehensive examination of the photocatalytic mechanisms, activity, and diverse applications of photocatalysts based on polar materials. We also briefly discuss the engineering design of polar photocatalysis in experiments and its scalability in the industry. This review outlines future trends and potential breakthroughs in the photocatalytic field using polar materials, projecting their transformative impact on environmental chemistry and energy engineering.
