in this work, mg-doped zno nanostructures were prepared in water under ultrasonic irradiation for 60 min without using any organic compounds or post preparation treatments. the prepared samples were characterized by x-ray diffraction (xrd), scanning electron microscopy (sem), transmission electron microscopy (tem), energy dispersive analysis of x-ray (edx), diffuse reflectance spectroscopy (drs...

The prevalence of antiviral drugs (ATVs) has seen a substantial increase in response to the COVID-19 pandemic, leading heightened concentrations these pharmaceuticals wastewater systems. hydrophilic nature ATVs been identified as significant factor contributing low degradation efficiency observed treatment plants. This characteristic often necessitates implementation additional steps achieve co...

T generation of H2 via photocatalytic water splitting has received considerable attention in recent years as efforts to optimize solar energy devices have accelerated. 3 Although visible photons are sufficiently energetic to split H2O and generate high-energy H2 fuel (requiring a 1.23 eV difference of its coupled half-reactions), materials that demonstrate this in any great yield are still not ...

Along with the increasing interest in exploring green and sustainable approaches organic synthesis, photon, cleanest energy form, has been widely utilized driving various transformations. In contrast to well-established photocatalysis utilizing homogeneous photosensitizers photocatalysts, solid-state semiconductors have received less but rapidly growing this field. Herein, we summarize recent d...

Abstract In recent years, many semiconductor materials have been applied to the photocatalysis technology. As a with wide band gap (3.37 eV), ZnO has received extensive attention in photocatalytic degradation of organic pollutants due its rich morphology, low cost and other advantages. However, ZnO, it can only absorb ultraviolet light (accounting for about 4% whole solar spectrum), which great...

While photocatalysis is considered a promising sustainable technology in the field of heterogeneous catalysis as well biocatalysis, figures merit (FOM) for comparing catalytic performance, especially between disciplines, are not established. Here, photocatalytic water splitting was conducted using semiconductor (NiO/La-NaTaO3) and bio-photocatalyst (Synechocystis sp. PCC 6803) same setup under ...

Plasmonic enhancement for electron–hole separation efficiency and visible light photocatalysis was achieved by Pd nanocube decoration on a ZnO nanolayer coated onto electrospun polymeric (polyacrylonitrile (PAN)) nanofibers. Since exciton formation and sustainable electron–hole separation have a vital importance for realizing better solar energy in photovoltaic and photocatalytic devices, we ac...

Based on the TiO2 photocatalysis mechanism, a new method of simultaneous desulfurization and denitrification from flue gas was proposed. Preparation of TiO2 photocatalyst, design of photocatalysis reactor and influencing factors for simultaneous removal of SO2 and NO, and removal mechanism of SO2 and NO were studied. After the optimal values of concentration of O2 in flue gas, the relative humi...
