“…Among them, constructing heterojunctions can effectively improve catalytic performance due to the enhanced light absorption ability and effective charge transfer rate. And the increasing number of heterojunctions such as C 3 N 4 /CeO 2 12 , BiOI/CeO 2 13 , AgI/CeO 2 14 and Co 3 O 4 /CeO 2 15 , are reported to apply for photocatalytic degradation of TC. Although the photocatalytic activity of binary composite has a great improvement, it is still some distance from practical application.…”

In this work, CeO2 nanosheets decorated with Ag2O and AgBr are successfully fabricated via a simple sediment-precipitation method. The as-prepared ternary Ag2O/AgBr–CeO2 composite with double Z-scheme construction was analyzed by various analytical techniques. Ag nanoparticles (NPs) used as the electron medium could reduce the recombination of photoelectrons and holes, thus leading to the improvement of photocatalytic performance of these catalysts. Due to the unique structure and composite advantages, the optimal Ag2O/AgBr–CeO2 photocatalysts exhibit the superior tetracycline (TC) degradation efficiency of 93.23% and favorable stability with near-initial capacity under visible light irradiation. This ternary Z-scheme structure materials will be the well-promising photocatalysts or the purification of antibiotic wastewater.

“…The separation effect of charges in p-n heterojunctions is higher than other heterojunctions leading to superior photocatalytic antibacterial activity. [240][241][242][243][244][245] CuS is a p-type semiconductor and is the material of choice for photocatalysis due to its narrow band gap and excellent physicochemical stability. [246][247][248][249] Ding et al synthesized CuS/g-C 3 N 4 heterojunction using a hydrothermal approach harnessing electrostatic adhesion.…”

The photocatalytic hydrogen evolution reaction is one of the important ways to convert solar energy into renewable hydrogen. In this work, the Co 9 S 8 hollow polyhedron was formed after sulfidation and calcination with the metalorganic framework ZIF-67. The hollow polyhedron Co 9 S 8 provides abundant support sites for Mn 0.05 Cd 0.95 S and effectively reduces the agglomeration degree of Mn 0.05 Cd 0.95 S. The Co 9 S 8 hollow polyhedron as the reaction site has a large specific surface area and a mesoporous structure, which is beneficial to the progress of the photocatalytic reaction. A series of tests showed that the introduction of Co 9 S 8 hollow polyhedron significantly improved the lighttrapping ability and exposed more reaction sites. Co 9 S 8 hollow polyhedrons are used as electron capture sites, which can effectively collect electrons and induce the interface charge transfer of Mn 0.05 Cd 0.95 S to Co 9 S 8 . Because the Co 9 S 8 -Mn 0.05 Cd 0.95 S composite catalyst had a strong light-trapping ability, abundant reaction sites and Co 9 S 8 -Mn 0.05 Cd 0.95 S heterojunction accelerate the separation and transfer of charges. Therefore, the hydrogen evolution rate of the 10%Co 9 S 8 -Mn 0.05 Cd 0.95 S composite catalyst was relatively high, which was 13.369 mmol g −1 h −1 . In addition, the 10%Co 9 S 8 -Mn 0.05 Cd 0.95 S composite catalyst still has good hydrogen evolution stability after four cycles. This research may supply a new idea for the preparation of high-efficiency photocatalysts with hollow structures.Novelty Statement: The Co 9 S 8 hollow polyhedron provides abundant support sites for M 0.05 C 0.95 S particles, which effectively reduces the degree of agglomeration. The Co 9 S 8 -M 0.05 C 0.95 S heterojunction catalyst not only accelerates the migration and transfer of electrons, but also provides abundant reaction sites. Therefore, the Co 9 S 8 -M 0.05 C 0.95 S composite catalyst has good catalytic activity.
