One-Step Self-Assembled WO/rGO Microspheres Photoanode Assembled Efficient Photocatalytic Fuel Cells for Simultaneous Organic Pollutant Degradation and Electricity Generation.

Photocatalytic fuel cells (PFCs) present a promising and environmentally friendly approach to simultaneously treat organic pollutants in wastewater and electricity generation. The development of photoanodes with high light absorption and carrier mobility is essential for enhancing the performance of PFCs but remains challenging. Herein, a one-step self-assembly strategy was adopted to develop flower-like WO/rGO microspheres for PFC devices.

Hydrodynamic cavitation degradation of Rhodamine B assisted by Fe-doped TiO: Mechanisms, geometric and operation parameters.

In this paper, a novel method, hydrodynamic cavitation (HC) combined with Fe-doped TiO, for the degradation of organic pollutants in aqueous solution is reported. The venturi tubes with different geometric parameters (size, shape and half divergent angle) are designed to obtain a strong HC effect. The structure, morphology and chemical composition of prepared Fe-doped TiO as catalyst are characterized via using XRD, SEM, TEM, XPS, UV-vis DRS and PL methods.

A novel Z-scheme sonocatalyst system, Er:YAlO@Ni(FeGa)O-Au-BiVO, and application in sonocatalytic degradation of sulfanilamide.

A novel Z-scheme coated composite, Er:YAlO@Ni(FeGa)O-Au-BiVO, was designed for sonocatalytic degradation of sulfanilamide and fabricated by sol-hydrothermal and calcination methods. The prepared sample was characterized by X-ray diffractometer (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), energy dispersive X-ray spectroscopy (EDX), UV-vis diffuse reflectance spectra (DRS), fourier transform infrared (FT-IR) spectra, Raman spectra and photoluminescence (PL) spectra. In Er:YAlO@Ni(FeGa)O-Au-BiVO, Ni(FeGa)O and BiVO form a Z-scheme sonocatalytic system, Er:YAlO as an up-conversion luminescence agent (from visible-light to ultraviolet-light) provides the ultraviolet-light for satisfying the energy demand of wide band-gap Ni(FeGa)O and Au nanoparticles as co-catalyst forms more active sites to enrich electrons.
