4、al-Free Cathode Material As Compared to Pt over a Co(II)/Co(III) Electrolyte for Dye-Sensitized Solar CellBG应用于染料敏化电池。FTO-BG的构建:: Homogeneously dispersed 0.1 wt% sample powders in 2-propanol solution were obtained by ultrasonication for 30 min. The resultant solution was deposited directly onto FTO/

5、glass (TEC-8, Pilkington) using an e-spray technique. First, the sample dispersion solutions were loaded into a plastic syringe equipped with a 27-gauge stainless steel hypodermic needle. The needle was connected to a high voltage power supply (ESN-HV30). A voltage of 8.0 kV was applied between a me

6、tal orifice and the conducting substrate at a distance of 5.5 cm. The feed rate was controlled by the syringe pump (KD Scientific Model 220) at a constant flow rate of 150 L min1. The electric field overcomes the surface tension of the droplets, resulting in the minimization of numerous charged mist

7、s. The sample electrodes were sintered at 300 oC for 30 min at atmosphere prior to device fabrication. 【RSC Advance】A facile one-step hydrothermal synthesis of a B doped graphene/rod-shaped TiO2 nanocompositeit has been demonstrated that both the reduction of GO and the doping of B into graphene frameworks as well as the rod shaped rutile TiO2 anchored on BG are achieved successfully during the hydrothermal reaction.
