TL;DR: Experimental data reveal that the incorporation of carbonyl groups into polymer matrix can significantly enhance singlet oxygen generation and suppress production of other reactive oxygen species.

TL;DR: By taking heptazine-based melon as an example, it is verified that enhanced hot-carrier generation could be obtained in semicrystalline polymeric photocatalysts, which is ascribed to the accelerated exciton dissociation at the abundant order-disorder interfaces.

TL;DR: Benefiting from the enhanced charge separation and transfer processes, the In2S3 nanosheets with S vacancies could simultaneously activate O2 into superoxide radicals via electron transfer under visible-light irradiation to display outstanding activity for the selective oxidation of alcohols to aldehydes with high conversion and selectivity.

TL;DR: This study provides an excitonic prospective on photocatalytic processes, and paves a new approach for pursuing systems with giant electron-hole interactions, by taking bismuth oxyhalide as examples.

TL;DR: It is demonstrated that ultrathin black phosphorus nanosheets exhibit an exotic, excitation-energy-dependent, optical switching effect in photocatalytic reactive oxygen species (ROS) generation, and establishes an in-depth understanding on the influence of many-body effects on photocatalysis.
