1Two-dimensional polymeric carbon nitride: structural engineering for optimizing photocatalysis显示文摘As a two-dimensional(2D) material, polymeric carbon nitride(g-C_3N_4) nanosheet holds great potentials in environmental purification and solar energy conversion. In this review, we summarized latest progress in the optimization of photocatalytic performance in 2D g-C_3N_4. Some of the latest structural engineering methods were summed up, where the relevant influences on the behaviors of photoinduced species were emphasized. Furthermore, the construction strategies for band structure modulation and charge separation promotion were then discussed in detail. A brief discussion on the opportunity and challenge of 2D g-C_3N_4-based photocatalysis are presented as the conclusion of this review.Wenjun Jiang Hui Wang Xiaodong Zhang Yongfa Zhu Yi Xie 2018Science China Chemistry2018,61,10:7
2Photocatalytic activity enhanced via surface hybridization显示文摘Surface hybrid inorganic semiconductors photocatalysts withπconjugated structure have recently been widely used in the field of photocatalytic environmental remediation and energy conversion.Surface hybridization is considered to be an efficient way to significantly enhance the photocatalytic activity by several times,completely inhibit photocorrosion of inorganic photocatalysts and expand the spectral response range of photocatalysts.This review provides a comprehensive overview of the surface hybridization definition,the principle of enhancing photocatalytic performance and the control factors of surface hybridization to promote photoactivity.Summarize the preparation and structural identification method of the surface hybrid photocatalyst.Special emphasis is placed on the various photocatalytic system construction of surface hybridization.The development of surface hybrid photocatalysts for pollutant degradation and energy conversion are further presented.Finally,the challenges and future development prospects of surface hybridization in photocatalysis are discussed.We hope this critical review can provide a clear picture of the state-of-the-art achievements and facilitate the applications of surface hybrid photocatalysts in environmental remediation and energy conversion.Yan Guo Huarui Li Wei Ma Wenxin Shi Yongfa Zhu Wonyong Choi 2020Carbon Energy2020,2,3:5
3Significant photocatalytic enhancement in methylene blue degradation of Bi2WO6 photocatalysts via graphene hybridization显示文摘The hybridization of graphene with Bi_(2)WO_(6)photocatalysts was employed to enhance the photocatalytic activity.The photocatalytic activity enhancements were dependent on the amount of graphene and it was found that the optimal hybridized amount of graphene was about 1.5 wt%,which was close to the monolayer dispersing of graphene on Bi_(2)WO_(6)surface.Up to four times of the photocatalytic activity was enhanced by the hybridization of graphene,compared with that of pristine Bi_(2)WO_(6).The enhancement mechanism of the photocatalytic activity was attributed to the higher separation efficiency and the inhibition of recombination of photoinduced electron-hole pairs.The electronic interaction was verified by the photoelectrochemical measurements.Feng ZHOU Yongfa ZHU 2012Journal of Advanced Ceramics2012,1,1:5
4Large dipole moment induced efficient bismuth chromate photocatalysts for wide-spectrum driven water oxidation and complete mineralization of pollutants显示文摘Herein,a wide-spectrum(~678 nm)responsive Bi8(CrO4)O11 photocatalyst with a theoretical solar spectrum efficiency of 42.0%was successfully constructed.Bi8(CrO4)O11 showed highly efficient and stable photocatalytic water oxidation activity with a notable apparent quantum efficiency of 2.87%(420 nm),superior to many reported wide-spectrum driven photocatalysts.Most remarkably,its strong oxidation ability also enables the simultaneous degradation and complete mineralization for phenol,and its excellent performance is about 23.0 and 2.9 times higher than CdS and P25-TiO2,respectively.Its high activity is ascribed to the giant internal electric field induced by its large crystal dipole,which accelerates the rapid separation of photogenerated electron-hole pairs.Briefly,the discovery of wide-spectrum bismuth chromate and the mechanism of exponentially enhanced photocatalytic performance by increasing the crystal dipole throw light on improving solar energy conversion.Xianjie Chen Yuan Xu Xinguo Ma Yongfa Zhu 2020National Science Review2020,7,3:4
5Highly efficient visible photocatalytic disinfection and degradation performances of microtubular nanoporous g-C3N4 via hierarchical construction and defects engineering显示文摘Herein,microtubular nanoporous g-C3N4(TPCN)with hierarchical structure and nitrogen defects was prepared via a facile self-templating approach.On one hand,the hexagonal tubular structure can facilitate the light reflection/scattering,provide internal/external active sites,and endow the electron with oriented transfer channels.The well-developed nanoporosity can result in large specific surface area and abundant accessible channels for charge migration.On the other hand,the existence of nitrogen vacancies can improve the light harvesting(>450 nm)and prompt charge separation by acting as the shallow charge traps.More NHxgroups in g-C3N4 framework can promote the interlayer charge transport by generating hydrogen-bonding interaction between C3N4 layers.Therefore,TPCN possessed highly efficient visible photocatalytic performances to effectively inactivate Escherichia coli(E.coli)cells and thoroughly mineralize organic pollutants.TPCN with the optimum bactericidal efficiency can completely inactivated5×10^6 cfu mL^-1 of E.coli cells after 4 h of irradiation treatment,while about 74.4%of E.coli cells were killed by bulk g-C3N4(BCN).Meanwhile,the photodegradation rate of TPCN towards methylene blue,amaranth,and bisphenol A were almost 3.1,2.5 and 1.6 times as fast as those of BCN.Furthermore,h^+and·O2^- were the reactive species in the photocatalytic process of TPCN system.Jing Xu Zhouping Wang Yongfa Zhu 2020Journal of Materials Science & Technology2020,47,14:3

7Enhancement of the degradation ability for organic pollutants via the synergistic effect of photoelectrocatalysis on a self-assembled perylene diimide (SA-PDI) thin film显示文摘A self-assembled perylene diimide(SA-PDI)film was prepared on an indium-tin-oxide(ITO)substrate and acted as a photoanode for the photoelectrocatalytic(PEC)degradation of some emerging contaminants under visible light irradiation(λ>420 nm)and applied voltage.Due to the synergistic effect,the photocatalytic degradation rate by the SA-PDI film under visible light irradiation and an applied voltage of 2.1 V was 2.72 times and 14.5 times those of the PC and EC processes,respectively.The visible light irradiation not only generated a promoting effect on electrocatalytic(EC)oxidation at potentials above1.2 V but also generated many more h+ for promoting the electrocatalytic oxidation of phenol.Furthermore,an applied voltage above 1.2 V could effectively improve the separation rate of electrons from the SA-PDI electrodes to the Pt electrodes,and then,much more ·O2-and ·OH could be generated for improving the photocatalytic(PC)oxidation efficiency.Therefore,the h+,·OH and ·O2-could improve the synergistic effect of phenol oxidation during the PEC process.Moreover,the SA-PDI film appeared to have satisfactory stability in the PEC process.The SA-PDI film was also proven to be effective for two other contaminants,namely,2,4-dichlorophenol,and ciprofloxacin.Hong Miao Jun Yang Guilong Peng Huiquan Li Yongfa Zhu 2019Science Bulletin2019,64,13:2
