Novel S-scheme 2D/2D BiOBr/g-C3N4 heterojunctions with enhanced photocatalytic activity

“…Among them, g-C3N4 with its typical 2D structure has become a research hotspot owing to its unique features, such as appropriate energy band, non-toxicity, abundant raw materials, simple synthesis, and good thermal-chemical stability [18][19][20]. g-C3N4 has been widely used for H2 evolution [21,22], CO2 reduction [23], NOx removal [24], organic pollutant degradation, and bacteria inactivation [25][26][27][28].…”

1D/2D Heterostructured Photocatalysts: From Design and Unique Properties to Their Environmental Applications

“…[16,[37][38][39][40] To fully integrate the above-mentioned merits and mitigate the drawbacks of the single units, such as the low surface area of 1D nanowires and the tendency of 2D nanosheets toward restacking, the epitaxial growth of dissimilar dimensional materials is proposed as a route to synthesize dimensional heterogeneous photocatalysts. [6,[41][42][43][44] The designed synthesis and application of dimensional heterostructures with multifunctional materials use the synergism or the summation effects from different dimensional materials, and those newly developed materials may realize the unique dimensionalitydependent advantages and mitigate the disadvantages in using for different photocatalytic reactions as shown in Table 1. [17,[45][46][47][48][49][50][51] In this table, we summarized the performances of different 1D/2D heterogeneous photocatalysts used in various photocatalytic reactions, such as hydrogen production, pollutants removal, Table 1.…”

“…Nowadays, the top objectives of human development policy are to achieve sustainable production of clean energy and protect the ecological environment. [1][2][3][4][5][6] In the past few years, 1D nanowires/ nanotubes and 2D nanosheets have been extensively investigated as photocatalysts in the field of environmental protection and sustainable energy development due to their interesting…”

Surface Engineering of 2D Carbon Nitride with Cobalt Sulfide Cocatalyst for Enhanced Photocatalytic Hydrogen Evolution

“…[16] In recent years, g-C 3 N 4 has been widely used in the design of catalysts, especially different surface strategies. [17][18][19][20][21][22] Because of its shortened electron transport path, high specific surface area, and flexible surface, 2D g-C 3 N 4 can provide a good platform for the loading of surface-functionalized components. [23] It is being applied more and more to research in various fields and is considered a promising catalyst modified by different methods.…”

“…For example, Ren et al used an ultrasound-assisted method to prepare a novel S-scheme Sb 2 WO 6 /g-C 3 N 4 nanocomposite for photocatalytic part per billion (ppb)-level NO removal. [18] Wang et al constructed a 2D/2D La 2 Ti 2 O 7 /g-C 3 N 4 nanojunction as an efficient visible light-driven bifunctional photocatalyst for H 2 evolution and CO 2 reduction reactions. [19] However, there is a problem that g-C 3 N 4 has inherent defects of weak charge transfer efficiency and surface activation ability to limit the application.…”
