“…This conversion operated under solar light irradiation (for 120 min) was comparable with the conversion by nanoparticles reported by Bellardita et al . They used Pt-TiO 2 nanoparticles as the photocatalysts, wherein the highest glucose conversion of 62.1% was achieved after operation under solar light for 360 min . In addition, in this work, it was found that arabinose was detected as the main product, which exhibited a percentage of 24%.…”

TiO 2 nanofibers were fabricated by combination of sol−gel and electrospinning techniques. Ag-doped TiO 2 nanofibers with different Ag contents were prepared by two different methods (in situ electrospinning or wetness impregnation of Ag on TiO 2 nanofibers) and heat treated at 500 °C for 2 h under an air or N 2 atmosphere. The obtained catalysts were characterized by field emission scanning electron microscopy, X-ray diffraction, photoluminescence, and N 2 adsorption analyzed by the Brunauer− Emmett−Teller (BET) method. Photocatalytic glucose conversions with electrospun TiO 2 and Ag-doped TiO 2 nanofibers for production of high-value products were carried out. From different doping methods, the results indicated that 1 wt % Ag-TiO 2 nanofibers prepared by an in situ method with calcination under N 2 achieved the highest glucose conversion (85.49%). From several Ag loading contents (i.e., 0, 1, 2, and 4 wt %) in Ag-doped TiO 2 nanofibers, the nanofibers exhibited different glucose conversions [in order of 2 wt % (99.65%) > 1 wt % (85.49%) > 4 wt % (77.72%) > 0 wt % (29.64%)]. Arabinose, xylitol, gluconic acid, and formic acid were found as the high-value chemicals with the photocatalytic reaction of TiO 2 and Ag-doped TiO 2 nanofibers under UVA irradiation. Product yields of each converted chemicals from different photocatalysts from different Ag loading contents showed relatively same trends with the glucose conversion. From all results, it can be concluded that the good characteristics of 2 wt % Ag-TiO 2 nanofibers such as the smallest anatase crystallite size (8.25 nm) and the highest specific surface area (S BET = 53.69 m 2 / g) promoted the highest photocatalytic activity. Additionally, TiO 2 and Ag-doped TiO 2 nanofibers exhibited higher photocatalytic performance for glucose conversion than commercial TiO 2 (P25) and synthesized TiO 2 nanoparticles. Finally, Ag-doped TiO 2 nanofibers showed recycling ability with high photocatalytic glucose conversion after four-time use.

“…[89,97]. Bellardita et al doped N and W into the lattice of TiO 2 using a hydrothermal method and further surface modified by Pt [88]. It was found that hydrogen production rate on Pt/(N and W)-TiO 2 in photocatalytic reforming of glucose under natural solar light was as high as 1.0 mmol h −1 g cat −1 .…”

Hydrogen is considered to be an ideal energy carrier to achieve low-carbon economy and sustainable energy supply. Production of hydrogen by catalytic reforming of organic compounds is one of the most important commercial processes. With the rapid development of photocatalysis in recent years, the applications of photocatalysis have been extended to the area of reforming hydrogen evolution. This research area has attracted extensive attention and exhibited potential for wide application in practice. Photocatalytic reforming for hydrogen evolution is a sustainable process to convert the solar energy stored in hydrogen into chemical energy. This review comprehensively summarized the reported works in relevant areas, categorized by the reforming precursor (organic compound) such as methanol, ethanol and biomass. Mechanisms and characteristics for each category were deeply discussed. In addition, recommendations for future work were suggested.

“…As it is reported that the presence of Ti 3+ species in the TiO 2 matrix enhances the hydrogen production under visible light [84], runs in the presence of the sample F/Ti = 0.25 (the most coloured one) were carried out in a closed system under visible light irradiation by using formic acid as the sacrificial agent [6]. After 4 h of irradiation, a formic acid conversion of ca.…”

“…In the last 50 years, heterogeneous photocatalysis has developed in the field of environmental clean-up [1][2][3][4], conversion of solar energy and fuels production [5][6][7], and synthesis of high value added compounds [8][9][10][11][12]. Although a great interest was recently devoted to alternative photocatalysts [13][14][15][16], the most used one remains TiO 2 [5,17,18].…”
