“…Development of an efficient photoelectrode for use in a water splitting photoelectrochemical cell (PEC) is extremely challenging due to some strict physical requirements including adequate band edge positions bracketing the water redox potentials, substantial overpotentials for oxidation of water to form oxygen or the reduction of protons to produce hydrogen and sufficiently small band gap to provide absorption overlap with the solar spectrum [5][6][7]. Furthermore, other practical parameters such as stability under the operation conditions and economic viability have led to continue further research to find the optimized photocatalysts [8,9].…”

The sol-gel method is a simple and facile wet chemical process for fabricating advanced materials with high homogeneity, high purity, and excellent chemical reactivity at a relatively low temperature. By adjusting the processing parameters, the sol-gel technique can be used to prepare hollow sphere and 1D structural materials that exhibit a wide application in the fields of catalyst, drug or gene carriers, photoactive, sensors and Li-ion batteries. This feature article reviewed the development of the preparation of hollow sphere and 1D structural materials using the sol-gel method. The effects of calcination temperature, soaking time, pH value, surfactant, etc., on the preparation of hollow sphere and 1D structural materials were summarized, and their formation mechanisms were generalized. Finally, possible future research directions of the sol-gel technique were outlined.

“…However, further increasing the Pt loading onto CrÀ Ta : SrTiO 3 catalysts led to the formation of recombination centers due to a large population of photoinduced electron-hole pairs, resulting in turn in a decrease of H 2 evolution rate. [13,20] Based on these results, a Pt loading of 0.9 wt.% was applied throughout this study.…”

In this study, the effect of drying techniques on properties of Pt/CrÀ Ta : SrTiO 3 catalysts in photocatalytic water splitting reaction were investigated. Drying techniques directly affected platinum particle size, which influenced the Pt phases and optical properties, all of which impact the activity of photocatalysts. The performances of Pt/CrÀ Ta : SrTiO 3 catalysts were in the following order: microwave > infrared > sonication > rotary evaporation > hot-air oven. Among these techniques, microwave drying was the most efficient, providing high surface area, small platinum particle size and high percentage of platinum (II) oxide, which in turn led to the outstanding apparent quantum yield of H 2 per energy consumption (22.4 %/KWh), which was 5.7, 5.7, 44.8 and 9.3 times higher than that of infrared, sonication, rotary evaporation and hot-air oven, respectively. This result indicated that microwave technique provided efficient rapid and uniform heating rate with low energy consumption, leading to lowering the operating time period and cost.[a] Dr.
