TiO2Single-atom catalystPhotocatalysisDensity functional theoryHydrogen is a kind of sustainable clean energy. Sunlight-driven hydrogen evolution reaction(HER) from water splitting assisted by photocatalysts is very crucial for developing clean energy technologies. Single-atom catalysts, such as atomically ...
a high hydrogen evolution rate of 163 mmol h–1 m–2can be achieved using Pt/TiO2cryoaerogel, even without forced convection. When fabricated in an area of 1 m2and incorporated with economically feasible single-atom Cu/TiO2photocatalysts, the nanocomposites produce 79.2 ml of hydrogen...
Further, the photocatalytic performance of TiO2 is being severely limited by inefficient utilization of light source and rapid recombination of photogenerated electron–hole pairs (Dong et al., 2021; Li et al., 2021; Ma and Lang, 2020). Single-atom metal catalysts (SACs) have been of great ...

TiO2 based photocatalysts are effective antimicrobial/antiviral agents under ambient conditions with potential to be used even in indoor environment for inactivation of bacteria/viruses. Interestingly, recent studies highlight the effective disinfection of SARS-CoV-2 using TiO2 photocatalysts. Here, scope ...
Fine-tuning the coordination number of single-atom W has been achieved by anchoring single-atom incorporated onto Graphite carbon nitride (g-C3 N4 ) frameworks, which has been found to be essential for efficient photocatalytic CO2 reduction. The WN4 sample, with a moderate coordination number of...
whereas the same for the triply charged interstitial titanium atom is around 9.11–9.24 eV/interstitial titanium.82,114,115 Due to the low value of carrier mobility in rutile TiO2, the transport phenomenon is assumed to follow either small polaron (an electron or hole self-trapped by the...
Photocatalysis using semiconductors, principally TiO2, is an important research field whose basic phenomena and main results have been reported in recent reviews (see, e.g., Refs. (1–6)). By contrast, its commercialized applications are still not widespread. The most developed application is self...
As a traditional photocatalyst, UV-responsive TiO2 has been widely favored, but its light energy utilization is lower than that of g-C3N4 with a visible light response. However, the photogenerated carriers of g-C3N4 have a low separation efficiency. In this study, SiO2 was utilized as a carri...
