“…Moreover, high QY of 1.74% can be obtained on T-1 sample under monochromatic light at l ¼ 420 nm. To our knowledge, these are the highest QYs ever reported for stable oxide semiconductors under comparable conditions 18,53 , although they are still lower than other systems, for example, CdSe nanocrystals capped with dihydrolipoic acid 54 and Ni-decorated CdS nanorods 55 . In addition to its remarkable photocatalytic activity, T-1 exhibits very good stability as a photocatalyst.…”

“…This limitation, together with poor photo-corrosion stability of many semiconductors, limits significantly the number of potential photocatalyst materials. Figure 11 displays the quantum efficiency of photocatalytic water splitting plotted against wavelength of a wide range of inorganic materials (Osterloh 2008). Note that this interesting summary represents only the water-splitting component of the photocatalytic process, but it nevertheless highlights a range of potential materials for the combined H 2 O/CO 2 photochemical process.…”

Our present dependence on fossil fuels means that, as our demand for energy inevitably increases, so do emissions of greenhouse gases, most notably carbon dioxide (CO 2 ). To avoid the obvious consequences on climate change, the concentration of such greenhouse gases in the atmosphere must be stabilized. But, as populations grow and economies develop, future demands now ensure that energy will be one of the defining issues of this century. This unique set of (coupled) challenges also means that science and engineering have a unique opportunity-and a burgeoning challenge-to apply their understanding to provide sustainable energy solutions. Integrated carbon capture and subsequent sequestration is generally advanced as the most promising option to tackle greenhouse gases in the short to medium term. Here, we provide a brief overview of an alternative mid-to long-term option, namely, the capture and conversion of CO 2 , to produce sustainable, synthetic hydrocarbon or carbonaceous fuels, most notably for transportation purposes.Basically, the approach centres on the concept of the large-scale re-use of CO 2 released by human activity to produce synthetic fuels, and how this challenging approach could assume an important role in tackling the issue of global CO 2 emissions. We highlight three possible strategies involving CO 2 conversion by physico-chemical approaches: sustainable (or renewable) synthetic methanol, syngas production derived from flue gases from coal-, gas-or oil-fired electric power stations, and photochemical production of synthetic fuels. The use of CO 2 to synthesize commodity chemicals is covered elsewhere (Arakawa et al. 2001 Chem. Rev. 101, 953-996); this review is focused on the possibilities for the conversion of CO 2 to fuels. Although these three prototypical areas differ in their ultimate applications, the underpinning thermodynamic considerations centre on the conversionand hence the utilization-of CO 2 . Here, we hope to illustrate that advances in the science and engineering of materials are critical for these new energy technologies, and specific examples are given for all three examples.With sufficient advances, and institutional and political support, such scientific and technological innovations could help to regulate/stabilize the CO 2 levels in the atmosphere and thereby extend the use of fossil-fuel-derived feedstocks.

“…[1][2][3][4][5] Since the pioneering work by Fujishima and Honda, 1 a large number of photocatalysts have been developed for water splitting. 3,[6][7][8][9][10][11][12][13][14] Among these photocatalysts, TiO 2 -based photocatalysts have been extensively studied on account of their high activity, long-term stability, and low cost.…”
