“…CeO 2 nanosheets have a large specific surface area, which is conducive to the loading of semiconductors with matching conduction band and valence band positions on the surface of CeO 2 , so as to construct heterojunction and improve the catalytic performance of CeO 2 . [ 34 ] The morphology of Co 9 S 8 is shown in Figure 2b, from which it can be seen that Co 9 S 8 is a nanoparticle. Co 9 S 8 nanoparticles are heavily clustered, which is unfavorable for photoelectron‐hole separation, so the photocatalytic hydrogen evolution performance of a single Co 9 S 8 is not ideal.…”

Enriching the active sites of catalysts and artificially regulating the directional migration of photogenerated carriers are effective means to improve the catalytic activity of photocatalysts. In this work, CeO2 nanosheets are prepared by calcination at high temperatures, and the S‐scheme heterojunction photocatalyst CeO2@Co9S8 is prepared by coupling the Co9S8 nanoparticles prepared by hydrothermal method on CeO2 nanosheets. The large specific surface area of CeO2 nanosheets provides sufficient loading sites for Co9S8 and Co9S8 nanoparticles can effectively disperse with the help of CeO2 nanosheet structure, which effectively inhibits the agglomeration of nanoparticles. The high photosensitivity of Co9S8 increases the utilization of CeO2@Co9S8 S‐scheme heterojunction to visible light. The construction of S‐scheme heterojunction improves the separation efficiency of photogenerated carriers, prolongs the service life of photogenerated charges, retains the photogenerated electrons and holes with strong reduction and oxidation ability in the catalyst system, and improves the performance of photocatalytic hydrogen production. The hydrogen yield of 15 wt% Co9S8 supported CeO2@Co9S8 can reach 15.7 times CeO2 and 2.5 times Co9S8, and the composite catalyst has good stability. This work provides a new way for adjusting the surface structure and carrier behavior of photocatalysts.

Background: Neuroinflammation is a typical feature of many neurodegenerative diseases, including Alzheimer’s disease and Parkinson’s disease. Microglia, the resident immune cells of the brain, readily become activated in response to infection or injury. Uncontrolled and overactivated microglia can release pro-inflammatory and cytotoxic factors and are the major culprit in neuroinflammation. Hence, research into novel neuroinflammatory inhibitors is of paramount importance for the treatment of neurodegenerative diseases. Bacterial lipopolysaccharide, widely used in studies of brain inflammation, initiates several major cellular activities that critically contribute to the pathogenesis of neuroinflammation. Objective: This review will highlight the progress on terpenoids, an important and structurally diverse group of natural compounds, as neuroinflammatory inhibitors in lipopolysaccharide-stimulated BV-2 microglial cells over the last 20 years.
