This comprehensive review addresses the fundamentals of photocatalytic mechanism, recent developments in materials synthesis and reactor design.
Abstract A system of 5020 robotic fiber positioners was installed in 2019 on the Mayall Telescope, at Kitt Peak National Observatory. The robots automatically retarget their optical fibers every 10–20 minutes, each to a precision several microns, with reconfiguration time fewer than 2 minutes. Over next 5 yr, they will enable newly constructed Dark Energy Spectroscopic Instrument (DESI) measure spectra 35 million galaxies and quasars. DESI produce largest 3D map universe date expansion...
We have demonstrated heterogeneous photocatalytic degradation of microcystin-LR (MC-LR) by visible light activated carbon doped TiO(2) (C-TiO(2)) nanoparticles, synthesized a modified sol-gel route based on the self-assembly technique exploiting oleic acid as pore directing agent and source. The C-TiO(2) nanoparticles crystallize in anatase phase despite low calcination temperature 350 °C exhibit highly porous structure that can be optimized tuning concentration surfactant. nanomaterials...
Billions of litres wastewater are produced daily from domestic and industrial areas, whilst is often perceived as a problem, it has the potential to be viewed rich source for resources energy. Wastewater contains between four five times more energy than required treat it, bio-hydrogen—a clean vector, feedstock chemical fuel, widely recognised have role in decarbonisation future system. This paper investigates sustainable, low-energy intensive routes hydrogen production wastewater, critically...
This work investigated hydrogen production from biomass feedstocks (i.e., glucose, starch, lignin and cellulose) using a 100 mL h-type proton exchange membrane electrolysis cell. Biomass is promising process for production, although low in technology readiness level, but with series of recognised advantages: (i) lower-temperature conditions (compared to thermochemical processes), (ii) minimal energy consumption low-cost post-production, (iii) potential synthesise high-volume H2 (iv) smaller...
Electrolysis from biomass is a promising process for hydrogen generation and biowaste that still unexplored.The paper used lignocellulosic components food waste (banana cucumber peels) as feedstocks to explore through an H-type proton exchange membrane electrolytic cell.Polyoxometalates (PMo 12 ) were employed catalyst charge carrier during the pre-treatment stage in degradation process.Electrochemical characterisations conducted potential range of 0-1.20 V analyse electrochemical reaction...
Innovative sol–gel synthesis based on the self-assembling template method has been applied to synthesize mesoporous anion-doped TiO2 with N–F, S and C atoms using suitable surfactants reagents, improve simultaneously structural, morphological, electronic properties of nanomaterials achieve anion doping titania high visible light photoinduced reactivity. The incorporation species in structure resulted effective extension optical absorption range through formation intragap energy states....
The improvement of the solar efficiency photocatalytic materials is important for driven environmental remediation and energy harvesting applications. Photoelectrochemical characterization nitrogen fluorine codoped titanium dioxide (N,F-TiO2) was used to probe mechanism visible light activity. spectral photocurrent response under irradiation did not correlate with optical absorption spectrum N,F-TiO2; however, open-circuit photopotential measurements provided better correlation spectra....
Contaminants of emerging concern including pharmaceuticals and personal care products are increasingly detected at low concentrations in surface waters. Given the associated toxicity these compounds, there is potential for significant impacts on aquatic life food chain. Since most not biodegradable, they cannot be removed by secondary treatment processes conventional wastewater plants. Therefore, development alternative methods plays a critical role removal pharmaceuticals. Energy...
