Sub-10 nm rutile titanium dioxide nanoparticles for efficient visible-light-driven photocatalytic hydrogen production

Recent Progress in Energy‐Driven Water Splitting

“…Reduced TiO 2 : Optical absorption of TiO 2 from ultraviolet to visible spectral region can also be improved by introducing surface defects, which are dominated by Ti 3+ defects together with oxygen vacancies 38. Self‐doping with Ti 3+ avoids the introduction of unfavorable carrier recombination centers as well as thermal instability associated with the dopants.…”

Engineering oxygen vacancy on rutile TiO2 for efficient electron-hole separation and high solar-driven photocatalytic hydrogen evolution

“…Rutile TiO 2 is suitable for photocatalytic water splitting due to its appropriate band energy position. The photocatalytic activity of rutile TiO 2 is usually low mainly due to the less surface active sites and the high recombination rate of photogenerated electron-hole pairs [19][20][21], although some researchers obtained rutile TiO 2 with excellent photocatalytic performance by designing and controlling suitable structure [19,20]. Moreover, rutile TiO 2 absorbs only ultraviolet light due to the wide bandgap (~3.0 eV), which represents a small fraction of solar energy and limits the efficiency of solar-driven photocatalysis greatly [22].…”

Nanocarbons with Different Dimensions as Noble-Metal-Free Co-Catalysts for Photocatalysts

“…TiO 2 , as one of the most researched photocatalytic materials, has attracted much attention [3,27,28] due to its advantages of nontoxicity, low cost, and high photocatalytic activity [29,30]. Oh et al [31] employed an improved oxidation method to synthesize the fullerene/TiO 2 composites.…”
