“…For SrTiO 3 (Figure 1a), peaks are observed at 22.8°, 32.4°, 40.0°, 46.5°, 57.8°, 67.8°and 77.2°corresponding to the (1 0 0), (1 1 0), (1 1 1), (2 0 0), (2 1 1), (2 2 0), and (3 1 0) planes, which are characteristic of the SrTiO 3 cubic phase (JCPDS 00-35-0734) [39][40][41]. The XRD pattern for BiVO 4 (Figure 1b) contain peaks corresponding to the crystal planes (0 1 1), (1 1 2), (0 0 4), (0 2 0), (2 1 1), (0 1 5), (0 2 4), (À 2 2 0), (1 1 6) and (2 2 4), related to the monoclinic structure of BiVO 4 (JCPDS 01-083-1698) [22,38]. Finally, for the composite (Figure 1c), it is observed characteristic peaks from both BiVO 4 and SrTiO 3 phases.…”

“…Therefore, to solve these limitations, several strategies have already been proposed in the literature to improve the photocatalytic performance of materials, such as doping with other elements or combination with other semiconductor materials. Thus, a photoactive material that has been shown to be attractive due to its low cost, high crystallinity, durability, good stability, a material of easy synthesis, and non-toxicity is bismuth vanadate (BiVO 4 ) [22,23]. BiVO 4 is an important semiconductor that is widely used in photocatalytic processes such as the decomposition of dyes and the production of hydrogen, onwing its ability of light absorption in the visible region with a band gap ffi2.4 eV [22].…”

The COVID‐19 pandemic is still a continuing worldwide challenge for public health systems. Early and ultrasensitive identification of the infection is essential for preventing the spread of COVID‐19 by pre‐symptomatic or asymptomatic individuals, particularly in the community and in‐home settings. This work presents a versatile photoelectrochemical (PEC) immunosensor for SARS‐CoV‐2 detection based on a composite material formed by bismuth vanadate (BiVO4) and strontium titanate (SrTiO3). The PEC platform was denoted as BiVO4/SrTiO3/FTO, and it can be tuned for the detection of either Spike (S) or Nucleocapsid (N) protein by simply altering the antibody immobilized on the platform's surface. Chemical, morphological, and electrochemical characterizations were performed by X‐Ray Diffraction, Scanning Electron microscopy, Energy‐dispersive X‐ray spectroscopy, Electrochemical Impedance Spectroscopy, and Amperometry. With a simple sensing architecture of the PEC platform, it was possible to achieve a linear response range of 0.1 pg mL−1 to 1000 ng mL−1 for S protein and 0.01 pg mL−1 to 1000 ng mL−1 for N protein. The PEC immunosensors presented recovery values for the two SARS‐CoV‐2 proteins in artificial saliva samples between 97 % and 107.20 % suggesting a good accuracy for the proposed immunosensors.

“…Meanwhile, photocatalytic oxidative desulfurization (PODS) is an advanced approach in oxidative desulfurization due to its low energy consumption, compatibility with the environment, the ability to use sunlight, and low process cost. In this method, a strong catalyst is used under the in uence of light to accelerate the oxidation of sulfur compounds [3,4].…”

In order to improve the efficiency of desulfurization of petroleum derivatives, copper bismuth oxide/reduced graphene oxide (Bi7.38Cu0.62O11.69/rGO) nanocomposite was synthesized by sonochemical method. The synthesized nanocomposite was identified by FESEM, FT-IR, XRD, DRS, and EDS analyses. Based on XRD analysis, pure copper bismuth oxide is formed using hydrazine, while using sodium hydroxide does not lead to the desired product. FESEM images showed that the size of Bi7.38Cu0.62O11.69 particles decreases in the presence of rGO. The desulfurization results showed that the presence of rGO causes a significant increase in efficiency due to increased light absorption and reduced recombination rate, so that Bi7.38Cu0.62O11.69/rGOnanocomposite has an efficiency of 87%, while pure Bi7.38Cu0.62O11.69 has an efficiency of 68%. Also, it was found that the purity of the copper bismuth oxide has a great effect on the photocatalytic efficiency, so that by calcining the product and removing the impurities, the efficiency increases from 55% to 68%.

In this manuscript, an organic-inorganic hybrid nanocatalyst has been synthesized using an ionic liquid as a transfer agent, copper oxide nanoparticles as a support, and the highly active mono copper-substituted polyoxotungstate. Ultrasound-assisted extractive-catalytic oxidative desulfurization (UA-ECODS) method was proposed to remove the Benzothiophene (BT), Dibenzothiophene (DBT), and 4,6-Dimethyl dibenzithiophene (4,6-DMDBT) in diesel fuel and straight run gas oil. The process involves the simultaneous use of extraction technique by an ionic liquid ([BMIM][PF6]) and catalytic oxidation by a suitable heterogeneous catalyst. The experimental condition was optimized by response surface methodology. The removal efficiency in the three compounds was as follows: BT < DBT < 4,6-DMDBT. In addition, the kinetic behavior of the removal of all three sulfur compounds was according to a quasi-first-order model. The reaction rate constant and apparent activation energy was calculated at 5 different temperatures.
