“…After 3 h of simulated solar exposure, the yields of CO and CH 4 were 30.5 and 34.0 μmol g −1 , respectively, while the selectivity of CH 4 was 52.7%. Foghani et al, 178 through a simple wet impregnation and calcination process, codoped phosphorus and copper on g-C 3 N 4 , coupled with different amounts of TiO 2 (P25), and successfully obtained the codoped g-C 3 N 4 /TiO 2 heterostructure. Because of the codoping of phosphorus and copper, the light absorption region is extended to visible light, the band gap energy is reduced, the carrier recombination rate is inhibited, and the surface area is increased.…”

Carbon dioxide (CO 2 ) is one of the main causes of global warming. Scientists have found that the photocatalytic conversion of CO 2 using visible light can not only reduce CO 2 emissions and thus mitigate the rise of CO 2 concentration in the atmosphere but also produce high-value compounds and fuels, such as CH 4 , CO, HCOOH, and CH 3 OH. TiO 2 -based modified photocatalytic materials have the advantages of high performance and good chemical stability, so they have broad application potential in the field of CO 2 photocatalysis. So far, a lot of research has been done on the way of photocatalytic reaction and the development of materials, but these achievements still have a long way to go for practical engineering applications, and the modification of TiO 2 groups may be one of the ways to promote its engineering application ability. For this reason, this paper reviews the modification measures of defect engineering, photosensitization, heterojunctions, and so on, hoping to be helpful in follow-up research work in the fields of improving the performance of devices, improving the utilization of visible light, reducing the carrier recombination rate, and changing the efficiency of photocatalytic reduction. Among various modification methods, defect engineering and photosensitization have been applied, but heterojunction construction is still the most effective way to improve the reduction rate. Therefore, in this review, we mainly focus on the construction of heterojunctions to improve the reduction rate, especially on the progress of charge transfer mechanism of different heterojunctions. By summarizing the current research status, the future development of heterojunctions is reasonably considered and speculated.

“…Furthermore, the Cu/P co‐doping combined with Z‑scheme heterojunction was proved to be effective to enhance the photocatalytic performance of g‐C 3 N 4 by Mohammad's et al, although the doping mode was not explored in this work. [ 164 ] The Cu/P co‐doping was demonstrated to extend the light adsorption to visible region, increase the specific surface area, and suppress the recombination rate. An outstanding photocatalytic performance of 85.9 µmol g −1 h −1 from CO 2 to CH 3 OH was then obtained by the Cu/P co‐doped g‐C 3 N 4 /TiO 2 heterostructures after coupled with TiO 2 .…”

Effective photocatalytic carbon dioxide (CO2) reduction into high‐value‐added chemicals is promising to mitigate current energy crisis and global warming issues. Finding effective photocatalysts is crucial for photocatalytic CO2 reduction. Currently, metal‐based semiconductors for photocatalytic CO2 reduction have been well reviewed, while review of nonmetal‐based semiconductors is almost limited to carbon nitrides. Phosphorus is a promising nonmetal photocatalysts with various allotropes and tunable band gaps, which has been demonstrated to be promising non‐metallic photocatalysts. However, no systematic review about phosphorus structures for photocatalytic CO2 reduction reactions has been reported. Herein, the progresses of phosphorus structures as photocatalysts for CO2 reduction are reviewed. The fundamentals of photocatalytic CO2 reduction, corresponding properties of phosphorus allotropes, photocatalysts with phosphorus doping or phosphorus‐containing ligands, research progress of phosphorus allotropes as photocatalysts for CO2 reduction have been reviewed in this paper. The future research and perspective of phosphorus structures for photocatalytic CO2 reduction are also presented.

Antibiotics cause negative impacts on the ecosystem and people‘s health, and it is imperative to reduce antibiotic residuum in a green and sustainable way. There has been a broad application of photocatalytic technology in the sewage treatment field. Compared with metal oxides, graphite carbon nitride, as an n‐type non‐metallic semiconducting polymer, has an applicable energy gap, simple preparation and easily accessible. Yet the g‐C3N4 of simple preparation tends to have some crucial weaknesses like rapid charge carrier recombination, underutilization of the visible spectrum and incomplete mineralization, which severely confine its farther application. Element doping modification enormously improves the separation of g‐C3N4 photogenic hole‐charge, which is applied to the removal of antibiotics in wastewater. The doping modification of g‐C3N4‐based semiconductor photocatalysts and research progress in the photocatalytic degradation of various antibiotics (sulfonamides, β‐lactam, quinolones, tetracycline) in water are reviewed in this paper, and the preparation of g‐C3N4, the sorts and principles of elemental doping are investigated, with emphasis on the application of g‐C3N4 towards the photocatalytic degradation of antibiotics, and the existing problems and challenges in this field are put forward.
