A ternary nanostructured photocatalyst consisting of ZnO/TiO2/Au was designed to achieve an enhanced solar absorption due to the coupling of surface enhanced plasmonic absorption of metal and semiconductor excitons. TiO2 coated ZnO rods with an aspect ratio of 8-12 were decorated with citrate capped gold nanoparticles for photocatalytic degradation of organic pollutants in simulated waste water...

The co-sensitization of organic silyl-anchor dyes in dye-sensitized solar cells (DSSCs) using carbazole and coumarin dyes with organosilicon tethers for binding to titanium dioxide has been examined. We have succeeded in fabricating a high-performance DSSC with a light-to-electric energy conversion efficiency of 12.8% under one sun simulated solar irradiation.

The response of a representative virus and indicator bacteria to heating, solar irradiation, or their combination, was investigated in a controlled solar simulator and under real sun conditions. Heating showed higher inactivation of Escherichia coli compared to the bacteriophage MS2. Heating combined with natural or simulated solar irradiation demonstrated a synergistic effect on the inactivati...

The photodegradation of Direct Blue 258, a member of the group of azo dyes which are commonly used in the various branches of the industry, was studied. The photostability of this dye was not previously surveyed. Photocatalytic degradation method was evaluated. The both light source include solar simulated (UV 400 W lamp) and sun light (E= 400 W/m2) and titanium dioxide nanoparticles were used ...

Antibiotics, as typical emerging contaminants, are frequently detected in the aquatic environment due to their widespread and massive use, posing potential risks ecology human health. To characterize photodegradation behavior of antibiotics water environment, sulfamethoxazole (SMX) enrofloxacin (ENR) were selected this study, behaviors these two under UV simulated solar light irradiation invest...

Photoelectrochemical (PEC) conversion of solar light into chemical fuels is one of the most promising solutions to the challenge of sustainable energy. Graphitic carbon (IV) nitride polymer (g-CN) is an interesting sustainable photocathode material due to low-cost, visible-light sensitivity, and chemical stability up to 500 °C in air. However, grain boundary effects and limited active sites gre...

In this study, the photoreactivation and the modification of dark repair of E. coli in a simulated secondary effluent were investigated after initial irradiation under different conditions. The simulated solar exposure of the secondary wastewater was followed by exposure to six different low-intensity fluorescent lamps (blacklight blue, actinic blacklight, blue, green, yellow and indoor light) ...

Solar-assisted water electrolysis is a promising technology for storing the energy of incident solar irradiation into hydrogen as fuel. Here, an integrated continuous flow electrochemical reactor coupled to monolithic perovskite-silicon tandem cell demonstrated that provides light-driven solar-to-hydrogen conversion with efficiency exceeding 21% at 1-Sun equivalent light intensity and stable op...

In situ generated H 2 O from water on Pd–MoO 3 catalyst can oxide methane into methanol and methyl hydroperoxide with high selectivity under simulated solar light irradiation.
