“…Several research groups have attempted to correlate the UC PL properties of CQDs with their surface nitrogen doping and oxygen‐containing functional groups. It has been reported that the introduction of N‐CDs has significant potential to enhance photocatalytic efficiency compared to that of N‐free CDs/semiconductor composites, mainly attributed to N‐doping, which can effectively induce charge delocalization and reduce the work function of CDs [95] . Based on this study, Tang et al.…”

“…It has been reported that the introduction of N-CDs has significant potential to enhance photocatalytic efficiency compared to that of N-free CDs/semiconductor composites, mainly attributed to N-doping, which can effectively induce charge delocalization and reduce the work function of CDs. [95] Based on this study, Tang et al revealed that N-CDs/CdS have superior photocatalytic H 2 production activity under NIR irradiation. [96] As shown in Figure 6c, the absorption curve exhibited an obvious red-shift and extended the light absorption range up to approximately 800nm owing to the broad solar spectrum UC emission.…”

The ability to use the full solar spectrum energy in photocatalytic processes for environmental remediation and energy production has attracted worldwide attention. Efficient harvesting of near‐infrared (NIR) photons, especially in the wavelength range beyond 800 nm, is one of the main driving forces in photocatalytic research. The design of appropriate photocatalytic systems for wide‐range light‐harvesting from the UV to NIR regions is a promising method of maximizing the efficiency of solar energy utilization. This review comprehensively summarizes the recent progress in full‐solar‐light‐driven photocatalytic systems, including several strategies to harness NIR light and thermal energy. The corresponding photocatalytic mechanisms and design of binary or ternary heterogeneous systems are discussed in detail. Moreover, future perspectives and challenges are presented to inspire the development of further innovations in full‐solar‐light‐driven photocatalysis.

“…Many recent studies have also proposed multiple advantages of doping and mixedphase BiVO 4 systems over single-phase BiVO 4 photocatalysts [78][79][80]. This resulted in the extended light absorption capability, carrier mobility, and higher efficiency of BiVO 4 -based systems for photochemical reactions.…”

BiVO4 As a Sustainable and Emerging Photocatalyst: Synthesis Methodologies, Engineering Properties, and Its Volatile Organic Compounds Degradation Efficiency

Bismuth vanadate (BiVO4) is one of the best bismuth-based semiconducting materials because of its narrow band gap energy, good visible light absorption, unique physical and chemical characteristics, and non-toxic nature. In addition, BiVO4 with different morphologies has been synthesized and exhibited excellent visible light photocatalytic efficiency in the degradation of various organic pollutants, including volatile organic compounds (VOCs). Nevertheless, the commercial scale utilization of BiVO4 is significantly limited because of the poor separation (faster recombination rate) and transport ability of photogenerated electron–hole pairs. So, engineering/modifications of BiVO4 materials are performed to enhance their structural, electronic, and morphological properties. Thus, this review article aims to provide a critical overview of advanced oxidation processes (AOPs), various semiconducting nanomaterials, BiVO4 synthesis methodologies, engineering of BiVO4 properties through making binary and ternary nanocomposites, and coupling with metals/non-metals and metal nanoparticles and the development of Z-scheme type nanocomposites, etc., and their visible light photocatalytic efficiency in VOCs degradation. In addition, future challenges and the way forward for improving the commercial-scale application of BiVO4-based semiconducting nanomaterials are also discussed. Thus, we hope that this review is a valuable resource for designing BiVO4-based nanocomposites with superior visible-light-driven photocatalytic efficiency in VOCs degradation.
