Introduction to Photocatalytic Enhancement

What is/are Photocatalytic Enhancement?

Photocatalytic Enhancement - The achieved progress demonstrates that the photocatalytic enhancement of zeolite-based composites is predominantly dependent on the enhanced adsorption performance, as well as the high separation and transfer efficiency of photogenerated charge carriers. ^[1] The photocatalytic enhancement of the sol catalyst was considered as a result of the band gap narrowing and the synergistic effects of band attachment in the nanocomposite. ^[2] Besides, the introduced Fe2+ on ZnO surface seems more beneficial for the photocatalytic enhancement. ^[3] In this review, the fundamental characteristics of graphene composites for photocatalytic enhancement, different preparation methods, its application in the treatment of recalcitrant organic compounds under UV and visible spectrum and the speculated mechanisms are discussed. ^[4] It appears that the SPR effect and internal electron transfer ability of Au NPs, depending on their sizes, play a synergistic effect on the photocatalytic enhancement. ^[5] Our study reveals that the photocatalytic enhancement by the LEF effect is superior to that by the traditional heterojunction effect based on polar supporting materials. ^[6] Photocatalytic enhancements in TiO2-NAA-μQVs are identified by monitoring the photodegradation of model organics with absorbance bands at specific positions within the visible spectral region. ^[7] The MT clay assisted in producing higher hydroxyl radicals and improving the solid-state oxidation of CS within the adsorbent sub-layer for the photocatalytic enhancement of TiO2/CS-MT than its counterpart TiO2/CS. ^[8] Finally, possible mechanism for the photocatalytic enhancement of the composite were put forward. ^[9] Under UV irradiation, the photocatalytic enhancement is mainly ascribed to the efficient separation of photogenerated electron/hole pairs caused by the smaller-sized Ag NPs, whereas the photocatalytic enhancement under visible light irradiation is dominantly due to the LSPR effects of the larger-sized Au NPs. ^[10] The photocatalytic activity suggest that an intimate interface contact, extended visible light absorption and effective photo generated charge carrier separation contributed to the photocatalytic enhancement of the CdS@MoS2 core shell. ^[11] The photocatalytic enhancement was attributed to the high separation efficiency of photogenerated electron–hole pairs based on the formation of heterojunction structures between the WO3/Nb2O5 and ZnO. ^[12] The photocatalytic enhancement is not only due to the increased number of active sites (larger surface area) of the porous particles but also due to the synergistic effects of the different alloying elements. ^[13] The photocatalytic enhancement of flower-like ZnO was ascribed to its unique architecture, good crystallinity and superior optical properties. ^[14] The photocatalytic enhancement was due to the strong adsorption and the higher charge separation efficiency of as-prepared g-C3N4/Na-bentonite composites. ^[15] Notably, density functional theory (DFT) calculations were employed to further understand the mechanism of the photocatalytic enhancement with regard to the optical absorption property at atomic level. ^[16] The fast adsorption kinetics of this composite film resulted in photocatalytic enhancement. ^[17]

A possible photocatalytic enhancement mechanism of Pd-BiFeO3 composite was stated. ^[1] The possible photocatalytic enhancement mechanism of the synthesized composite was proposed as well. ^[2] To gain better insights, a possible photocatalytic enhancement mechanism was also proposed. ^[3] Finally, the possible photocatalytic enhancement mechanism was proposed. ^[4]

Obviou Photocatalytic Enhancement

8S hollow heterojunction exhibits an obvious photocatalytic enhancement to about ~5822. ^[1] ZnO-g-C3N4@PET composite has been prepared by hydrothermal method, photoluminescence results indicated that ZnO-g-C3N4@PET has a low photo-generated charge recombination rate, while g-C3N4 improves the visible light response of the composite and exhibits an obvious photocatalytic enhancement effect. ^[2]

photocatalytic enhancement mechanism

The photocatalytic enhancement mechanisms can be attributed to multiple strategies, such as the large specific surface area, the enhanced conductivity, the generation of self-doped defects in Z-scheme m-TiO2/TiO2-x/CeO2-x heterojunction, which are beneficial for providing more active sites, extending the absorption range of solar light, and suppressing the recombination of photo-excited carriers. ^[1] In addition, the photocatalytic enhancement mechanism of BN/SW heterojunction was proposed. ^[2] The results of charge transfer dynamics and DFT calculation reveal that the photocatalytic enhancement mechanism is primarily attributed to the synergistic effects of crystallization of CN, excellent conductivity of Ti3C2 and well-constructed Schottky heterojunction. ^[3] In addition, the photocatalytic enhancement mechanism of the catalyst was studied. ^[4] A possible photocatalytic enhancement mechanism of Pd-BiFeO3 composite was stated. ^[5] The possible photocatalytic enhancement mechanism of the synthesized composite was proposed as well. ^[6] Finally, the photocatalytic enhancement mechanism for the TiO2/SnO heterojunction was proposed based on band alignments calculation and the active species trapping experiments. ^[7] In view of all the obtained experimental results, a photocatalytic enhancement mechanism for the MWCNTs/BiOCl composite is presented. ^[8] To gain better insights, a possible photocatalytic enhancement mechanism was also proposed. ^[9] Finally, the photocatalytic enhancement mechanism over p-Ag2S/n-BiVO4 was discussed. ^[10] Finally, the possible photocatalytic enhancement mechanism was proposed. ^[11] Furthermore, density functional theory calculations were applied to further understand the photocatalytic enhancement mechanism of the optical absorption properties at the atomic level after Co- or Mo-doping. ^[12] Based on experiment results, the photocatalytic enhancement mechanism for organic pollutants degradation and E. ^[13] • Photocatalytic enhancement mechanism of Cu3P/g-C3N4 composite was proposed. ^[14] The photocatalytic enhancement mechanism was elucidated by experimental means and theoretical calculations. ^[15]
