چکیده
Chemicals and Materials All chemicals used in the experiments (KBr, Fe2(SO4)3, H2SO4, ethanol, Rhodamine B) are analytical grade or better provided by Sinopharm Co., China. All aqueous solutions are prepared with deionized water (18.2 MΩ, Milli-Q, Millipore Corp., France). ITO glass slides were washed in an ultrasonic cleaner by isopropanol and deionized water for several times and dried by blowing pure nitrogen gas. The slurry of TiO2 nanoparticles (average diameter: 20 nm,) is coated on the clean ITO substrate by doctor blading method to form a square TiO2 spot (500 μm by 500 μm). The ITO slide is sintered at 450 oC for 2h in a muffle furnace. The area except the TiO2 spot is encapsulated by a thin insulating film before use. The images relevant to the photoanodes were shown in Fgiure S1.

Virtual Environment Online for the Project- Based Learning Session
22 Abstract—Project-Based Learning (PBL) has become a necessity for the Moroccan higher education reform. PBL is an approach that transforms teaching from "teachers telling" to "students doing". However, implementing PBLs brings new challenges to higher education. In this paper, we present a set of Technology-enhanced Learning environments integrating the needed aspects in a synergetic way to f...
متن کاملSynergetic effect of metal nickel and graphene as a cocatalyst for enhanced photocatalytic hydrogen evolution via dye sensitization
Exploiting new, low-cost and efficient electrocatalysts for hydrogen evolution reaction (HER) is important to resolve the energy crisis and environment pollution. In this work, graphene decorated with Ni nanoparticles (NPs) were synthesized via one-pot reduction using graphene oxide (GO, the obtained composite was denoted as GN) as a precursor. The as-prepared composite GN exhibits much better ...
متن کاملSynergetic Effect of Ultrasound, the Heterogeneous Fenton Reaction and Photocatalysis by TiO2 Loaded on Nickel Foam on the Degradation of Pollutants
The synergistic effect of ultrasound, the heterogeneous Fenton reaction and photocatalysis was studied using a nickel foam (NF)-supporting TiO₂ system and rhodamine B (RhB) as a target. The NF-supporting TiO₂ system was prepared by depositing TiO₂ on the skeleton of NF repeatedly and then calcining it. To optimize the conditions and parameters, the catalytic activity was tested in four systems ...
متن کاملSynergetic Effect of the Mixed Anionic/Non-Ionic Collectors in Low Temperature Flotation of Scheelite
The synergetic effect of four octaphenyl polyoxyethyienes (TX) on low temperature flotation of scheelite at 9–11 ◦C was investigated through flotation experiments, and the adsorption mechanism was studied by way of surface tension, zeta potential, and adsorption measurement. The results show that the presence of the four octaphenyl polyoxyethyienes can improve scheelite flotation in a low conce...
