“…44 A series of studies have been conducted following that, and TiO 2 has become one of the most effective semiconductor photocatalysts. [45][46][47][48][49][50][51][52][53][54][55][56][57][58][59][60][61][62] However, the electronic band gap in the ultraviolet (UV) wavelength regime of TiO 2 has largely limited the overall photocatalytic efficiency. Narrowing the band gap of TiO 2 is vital to achieve efficient absorption of sunlight and high efficiency for solar hydrogen production.…”

Over the past decades, there have been many projections on the future depletion of the fossil fuel reserves on earth as well as the rapid increase in green-house gas emissions. There is clearly an urgent need for the development of renewable energy technologies. On a different frontier, growth and manipulation of materials on the nanometer scale have progressed at a fast pace. Selected recent and significant advances in the development of nanomaterials for renewable energy applications are reviewed here, and special emphases are given to the studies of solar-driven photocatalytic hydrogen production, electricity generation with dye-sensitized solar cells, solidstate hydrogen storage, and electric energy storage with lithium ion rechargeable batteries.

“…There has been a large number of research works focusing on the doping of TiO2 by various dopants: including anions (B [9], C [10], N [11][12][13][14][15][16], chalcogen [17], and halogen atoms [11,[18][19][20][21][22][23]) as well as cations [11,[18][19][20][21][22][23][24][25][26][27][28][29]. Most of initial attempts were focused only on narrowing the band gap of TiO2.…”

In the present study, photocatalytic hydrogen production from water/methanol solution was investigated over cerium and nonmetal (B/C/N/S) co-doped titanium dioxide catalyst under visible light irradiation. The cerium and nonmetal co-doped titania photocatalysts were prepared by co-precipitation and characterized by surface area and pore size analysis, X-ray diffraction analysis, diffuse reflectance UV-Vis spectroscopy analysis, and photoluminescence analysis. The UV-Visible spectra showed that incorporation of cerium and nonmetals to TiO 2 resulted in narrow band gap and improved absorption of visible light. The band gap energy of co-doped samples depended on the properties of nonmetals. Photoluminescence studies showed that the radiative recombination rates of photogenerated electron-hole pairs were effectively suppressed by the addition of cerium and nonmetals and contributed to higher activity. The highest hydrogen production of 206 lmol/h was obtained for Ce-N-TiO 2 sample, which can be attributed to the higher surface area, higher absorption of visible light, and higher separation efficiency of electron-hole pairs in Ce-N-TiO 2 .
