“…Despite the fact that the reported efficiencies for both reactions were very low, this study exhibited the potential ability of H-containing antibiotics as a source of H 2 production. Levofloxacin (LEV) is another antibiotic, which was used as a sacrificial agent for H 2 generation . The photocatalytic degradation of LEV was researched over Z-scheme Ag/g-C 3 N 4 -Ag-Ag 3 PO 4 (110) photocatalyst.…”

Heterogeneous photocatalytic reactions have experienced many efforts in developing new materials to tackle environmental and energy crises through utilizing appropriate photocatalysts in wastewater treatment, H2 generation, organic transformations, CO2 reduction, N2 photofixation, and biomass conversion. While these processes are addressed in the literature separately, a recent innovative viewpoint is to employ a photocatalytic system to achieve simultaneously two or more functions. The challenging point is that the combination of two functions in one photocatalytic system requires a novel design and engineering of an appropriate semiconductor photocatalyst with special characteristics for each application in a particular environment. Recently, graphitic carbon nitride (g-C3N4) with its unique physicochemical properties has gained tremendous attention among researchers due to its great potential for utilization as a dual-functional photocatalyst. In this study, the role of morphological engineering and band gap manipulation in heterojunction formation of g-C3N4 will be considered. These newly applied strategies are useful to improve the photocatalytic activity of g-C3N4 in different simultaneous reactions. Furthermore, detailed information on the application of g-C3N4-based materials in dual-functional simultaneous processes will be discussed in different reactions: namely, (i) photocatalytic H2 generation combined with oxidation of organic pollutants, (ii) photocatalytic mineralization of organic pollutants and reduction of the obtained CO2, (iii) photocatalytic removal of a mixture of organic pollutants and heavy metals, (iv) H+ and CO2 reduction, (v) photocatalytic H2 generation in conjunction with oxidation of organic substrates/biomass to value-added products, and (vi) simultaneous H2 and H2O2 production. These combined approaches could provide efficient and sustainable strategies for simultaneous reactions involved in both energy and environmental issues.

“…Thus, novel systems like the Cu 2 O‐RGO/BiVO 4 Z‐scheme nanocomposite has been constructed to achieve the simultaneous solar‐driven CO 2 reduction and benzyl alcohol oxidation, producing value‐added C‐fuels and benzaldehyde that would require high energy requirements with the conventional synthesis route 353 . Although carbon nitride‐based systems have yet to be utilized in simultaneous reactions with CO 2 reduction, novel systems such as the Ag/g‐C 3 N 4 ‐Ag‐Ag 3 PO 4 (110) Z‐scheme heterojunction, 354 CQD implanted g‐C 3 N 4 , 355 and ultrathin porous g‐C 3 N 4 bundles 356 have been constructed for simultaneous photocatalytic waste water treatment and water splitting reaction, indicating its potential for further development toward CO 2 RR in the near future.…”

CO2 capture and conversion has been prospected as an auspicious technology to simultaneously tackle the rise in global CO2 emission and produce value‐added fuels with the goal of accomplishing carbon neutrality. A sustainable route to achieve this is via the utilization of solar energy, thereby harnessing the abundant and nonexhaustive resource to shift our reliance away from rapidly depleting fossil fuels. Graphitic carbon nitride (g‐C3N4) and its allotrope have earned its rank as a fascinating metal‐free photocatalyst due to its superior stability, high surface‐area‐to‐volume ratio, and tunable surface engineering. By leveraging these properties, robust carbon nitride‐based nanostructures are engineered for photocatalytic CO2 conversion to energy‐rich C1C2 product, which is indispensable in the chemical industry. Thus, this review presents the latest panorama of experimental and computational research on tuning the local electronic, surface chemical coordination environment, charge dynamics and optical properties of low‐dimensional carbon nitride and its allotropes toward highly selective and efficient CO2 photoconversion. To name a few, structural engineering, point‐defect engineering, heterojunction construction, and cocatalyst loading. To advance this frontier, critical insights are elucidated to establish the structure‐performance relationship and unravel primary factors dictating the selectivity of C1C2 molecules from CO2 reduction. External‐field assisted photocatalysis such as with electric (photoelectro‐) and heat (photothermal) is discussed to uncover the synergistic contributions that drive the development in photochemistry. Last, future challenges and prospects are outlined for the potential application of solar‐driven CO2 conversion, along with the scale‐up strategy from the economic viewpoint toward the rational development of high‐efficiency carbon nitride catalysts.

“…However, the poor absorption of broadband light and high recombination rate of photoinduced e À -h + pairs hinder the further application of g-C 3 N 4 . [98] Hence, a mass of measures have been taken to boost the photocatalytic efficiency of g-C 3 N 4 , such as doping, [99][100][101] dye sensitization, [102] constructing heterojunctions, [103][104][105] and loading co-catalysts. [103][104][105] In this part, various TMPs are used as classification criteria to clearly illustrate their effects on the photocatalytic performance of g-C 3 N 4 .…”

Photocatalytic hydrogen evolution can effectively alleviate the troublesome global energy crisis by converting solar energy into the chemical energy of hydrogen. In order to realize efficient hydrogen generation, a variety of semiconductor materials have been extensively investigated, including TiO2, CdS, g‐C3N4, metal‐organic frameworks (MOFs), and others. In recent years, to achieve higher photocatalytic performance and reach the level of large‐scale industrial applications, photocatalysts decorated with transition metal phosphides (TMPs) have shone brightly because of their low cost, stable physical and chemical properties, and substitution for precious metals of TMPs. This Review highlights the preparation methods and properties associated with photocatalysis of TMPs. Moreover, the H2 generation efficiency of photocatalysts loaded with TMPs and the roles of TMPs in catalytic systems are also studied systematically. Apart from being co‐catalysts, several TMPs can also serve as host catalysts to boost the activity of photocatalytic composites. Finally, the development prospects and challenges of TMPs are put forward, which is valuable for future researchers to expand the application of TMPs in photocatalytic directions and to develop more active photocatalytic systems.
