From Photoreceptors to Photoelectrodes: Integrating Biological Light-Harvesting Mechanisms with Nanostructured Photoelectrochemical Systems
Abstract: The efficient conversion of solar energy into electrical and chemical energy is a major scientific challenge of the twenty-first century. Natural photoreceptors provide valuable models for addressing this challenge because they have evolved highly efficient mechanisms for capturing and converting light energy. Biological systems such as rhodopsins, bacteriorhodopsins, proteorhodopsins, cryptochromes, phototropins, and phytochromes employ chromophore-driven photoinduced electron and proton transfer processes to initiate a wide range of physiological responses, including …

Use of Molybdenum Doped Titanium Dioxide as Nanophotocatalyst in the Degradation of Methylene Blue under Visible Light
Abstract: The Earth is facing environmental pollution in its different facets, out of which water pollution is a major problem. Photocatalysis, which is an important part of advanced oxidation processes, is such a technology, which will be beneficial for waste water treatment due to its green chemical nature. In the present work, the photocatalytic degradation of methylene blue (MB) was carried in the presence of molybdenum doped titania nanophotocatalyst and progress …

Synthesis and Characterization of Co-Doped ZnO Nanoparticles by Electrochemical Method: Photodegradation Kinetics of Bromophenol Blue Dye, Textile Effluent and Study of Antibacterial Activity
Abstract: ZnO nanoparticles doped with cobalt were synthesized by electrochemical method. The crystal structure and surface morphology were characterized by X-Ray diffraction and Scanning electron microscopy. The optical properties were studied by UV-Vis spectroscopy and from this the band gap energy was found to be 3.17 eV. The XRD data revealed that the crystalline size to be ~21.23 nm. The functional group test was done by FTIR-spectroscopy. SEM results showed the …

Advanced nanosized polymer composites with oxides of TiO2 and ZnO (review)
Abstract: Тhis study discusses recent advances in photocatalytic applications of multifunctional oxide nanocomposites with polymers for the treatment of different pollutants from the water. The analysis of literature in the chapters makes it possible to single out the polymers and nanocomposites that are most promising from the point of developing new technologies. It is shown that composite materials containing TiO2 and ZnO after additional studies can be recommended for self-cleaning protective …

A Review on Advancements and Challenges of Catalytic and Non-Catalytic Waste Water Treatment Processes
Abstract: AbstractClean drinking water is a basic amenity to be ensured for all. As water resources are becoming increasingly scarce due to the rising imbalance between freshwater availability and consumption and many of the water resources are polluted by anthropogenic sources such as industrial, agricultural waste and household, therefore, treatment of wastewater remains a critical need before leaving it to natural water streams. Traditional wastewater treatment processes include filtration, adsorption, activated …
