“…Regardless of the numerous photocatalysts like TiO 2 [5], CdS [6] and C 3 N 4 [7] discovered for solar water splitting these years, the application of photocatalysis is still lagged because of the low transformation efficiency between solar energy and chemical energy [8][9][10]. The efficiency of semiconductor-based photocatalysis is usually restricted by the separating rates of photoinduced electrons and holes [11,12]. Particularly, photoinduced carriers recombinate quickly in pristine photocatalysts and thus hamper the photochemical reaction [13,14].…”

Fast recombination of photoinduced carriers inhibits the performance of photocatalysts. By constructing heterojunctions, built-in electric fields can be formed to separate electrons and holes and finally enhance the photocatalytic efficiency. Herein, a Mn x Cd1−x Se in situ heterojunction was fabricated by a facile solvothermal method to draw upon this advantage. Absorption spectra show that the light absorption of CdSe raises up obviously after the doping of Mn2+. Best performance was achieved when the doping percent of Mn2+ was 50%. This Mn0.5Cd0.5Se sample exhibits a 7.2 folds increase in hydrogen evolution against pure CdSe owing to the fast electron transportation. Moreover, it proves well stability in an 18 h cycling test and gains a 6.7% apparent quantum yield under 420 nm light. In summary, this work constructs an in situ heterojunction to enhance the photocatalytic hydrogen evolution efficiency and sheds light on a feasible way for the application of photocatalysis.

A simple solution-phase route to synthesize mesoporous anatase TiO 2 nanocrystallites at room temperature was presented. TiO 2 nanocrystallites were prepared via a unique hydrolysis of titanium complexes in the presence of H 3 BO 3 . The mean size of the as-obtained TiO 2 nanocrystallite was in about 10 nm. And they possess large surface area of 48.6 m 2 g 1 and the dominant pore size of 4.3 nm. The effect of aging time on crystallinity was studied. For crystallization occurred at room temperature, the longer the aging time, the greater the crystallinity. KeywordsDownloaded by [University of Cambridge] at 17:49

A novel nanocomposite of ZnO-PbO with flower-like nanostructure was fabricated from zinc acetate and lead nitrate as principle raw materials via an in situ process. The novelty of this study consists in the use of a common approach for fabricating of ZnO and PbO nanoparticles simultaneously. From these experiments the conclusion might be drawn that Zn(NH 4 ) 2 4z ions and Pb(OH) 2 act as precursors for the nucleation and growth of ZnO and PbO respectively under microwave irradiation. The precursors formation were carried at two stages: reaction between zinc ions and lead nitrate with ammonium ion and hydroxide sodium respectively. The average crystalline size of Zno and PbO has been analysed by X-ray diffraction (XRD) pattern and estimated to be 43?5 and 54?5 nm for ZnO and PbO respectively. Brunauer-Emmet-Teller (BET-N 2 ) analyses of as prepared material demonstrated that this nanostructure material has a high specific surface area, as high as 150 m 2 g 21 which can be promising targets for adsorbent materials. The Formation mechanism of ZnO-Pbo nanocomposite is also studied.
