Today, the development of green nanocatalysts is among the popular topics due to the need for energy production and the cleaning of organic pollutants. In this approach, Bacillus thuringiensis, a bacterium, was used as a biosupport of ruthenium/nickel co-doped zinc nanoparticles (btRNZn NPs) to release hydrogen from the methanolysis of sodium borohydride (NaBH 4 ). In addition, their photocatalytic activity was reported against Methyl Orange (MO) organic dye. This study focused on the preparation, characterization, and catalytic and photocatalytic activity of the btRNZn biocatalyst for the release of hydrogen from the methanolysis of NaBH 4 and removal of MO dye. According to TEM analysis, the average size of btRNZn NPs was found to be 11.78 nm; in addition, btRNZn NPs showed a photodegradation effect of 68.2% against MO dye at 90 min, and its photocatalytic mechanism was discussed. The effects of the catalyst, substrate, and temperature in the methanolysis reaction of NaBH 4 in the presence of the catalyst were investigated extensively. The reaction kinetics was calculated, and TOF, activation energy, and enthalpy energy were measured as 2497.14 h −1 , 14.89 kJ/mol, and 12.35 kJ/mol, respectively. It was observed that the methanolysis process is a first-order reaction based on the amount of the catalyst and substrate. This study aimed to synthesize a nanobiocatalyst (btRNZn NPs) by a biological method, and it will be used as a great photocatalyst to prevent wastewater pollution; also, it can be an excellent catalyst to produce hydrogen from NaBH 4 methanolysis. The application of btRNZn NPs in solar photocatalysis to prevent wastewater pollution and to research it for energy production through hydrogen creation are both made clear by these studies.

“…As they usually are magnetizable species, NCs are easily separable from the reaction medium due to their insolubility [ 23 ]. According to the existing literature [ 24 , 25 , 26 ], relevant examples of NCs include nanoparticles containing cobalt [ 27 , 28 , 29 , 30 , 31 ], gold [ 32 , 33 , 34 ], iron [ 35 , 36 , 37 , 38 , 39 , 40 ], nickel [ 41 , 42 , 43 , 44 ], palladium [ 45 , 46 , 47 , 48 , 49 , 50 ], and platinum [ 42 , 51 , 52 , 53 ]. Among the most diverse uses of NCs are biodiesel production [ 54 , 55 , 56 , 57 , 58 , 59 , 60 , 61 , 62 , 63 ], dyeing [ 64 , 65 , 66 , 67 , 68 , 69 , 70 , 71 , 72 , 73 …”

Biofuels and Nanocatalysts: Python Boosting Visualization of Similarities

et al. 2023

View full text Add to dashboard Cite

Among the most relevant themes of modernity, using renewable resources to produce biofuels attracts several countries’ attention, constituting a vital part of the global geopolitical chessboard since humanity’s energy needs will grow faster and faster. Fortunately, advances in personal computing associated with free and open-source software production facilitate this work of prospecting and understanding complex scenarios. Thus, for the development of this work, the keywords “biofuel” and “nanocatalyst” were delivered to the Scopus database, which returned 1071 scientific articles. The titles and abstracts of these papers were saved in Research Information Systems (RIS) format and submitted to automatic analysis via the Visualization of Similarities Method implemented in VOSviewer 1.6.18 software. Then, the data extracted from the VOSviewer were processed by software written in Python, which allowed the use of the network data generated by the Visualization of Similarities Method. Thus, it was possible to establish the relationships for the pair between the nodes of all clusters classified by Link Strength Between Items or Terms (LSBI) or by year. Indeed, other associations should arouse particular interest in the readers. However, here, the option was for a numerical criterion. However, all data are freely available, and stakeholders can infer other specific connections directly. Therefore, this innovative approach allowed inferring that the most recent pairs of terms associate the need to produce biofuels from microorganisms’ oils besides cerium oxide nanoparticles to improve the performance of fuel mixtures by reducing the emission of hydrocarbons (HC) and oxides of nitrogen (NOx).

“…In electrochemical determinations usually, the bare electrode has some limitations, such as poor electroactive sites, high resistance of electron transfer, and low sensitivity. Bare electrodes modification with nanomaterials is one of the common ways for overcoming these limitations (Karimi-Maleh et al 2022b ; Ashrafzadeh Afshar et al 2022 ; Karaman et al 2022 ; Jafarzadeh et al 2022 ). Due to specific and significant properties that have been provided by nanomaterials, these materials have been noted and widely used in various fields of science and technology, such as energy storage, environmental application, sensor, food safety, hydrogen production, catalyst, biotechnology, optics, and electronics (Buledi et al 2022 ; Karimi-Maleh et al 2022c ; Hojjati-Najafabadi et al 2021 , 2022a ; c ; Ashrafzadeh Afshar et al 2022 ; Karaman et al 2022 ; Jafarzadeh et al 2022 ; Khatoon et al 2022 ; Coguplugil 2022 ; Hashemi et al 2022 ; Mansoorianfar et al 2022 ).…”

In this report, Azithromycin (Azi) antibiotic was measured by carbon paste electrode (CPE) improved by graphene nanoribbon–CoFe 2 O 4 @NiO nanocomposite and 1-hexyl-3 methylimidazolium hexafluorophosphate (HMIM PF 6 ) as an ionic liquid binder. The electrochemical behavior of Azi on the graphene nanoribbon–CoFe 2 O 4 @NiO/HMIM PF 6 /CPE is investigated by voltammetric methods, and the results showed that the modifiers improve the conductivity and electrochemical activity of the CPE. According to obtained data, the electrochemical behavior of Azi is related to pH. under optimum conditions, the sensor has linear ranges from 10 µM to 2 mM with a LOD of 0.66 µM. The effect of scan rate and chronoamperometry were studied, which showed that the Azi electro-oxidation is diffusion controlled with the diffusion coefficient of 9.22 × 10 –6 cm 2 /s. The reproducibility (3.15%), repeatability (2.5%), selectivity, and stability (for 30 days) tests were investigated, which results were acceptable. The actual sample analysis confirmed that the proposed sensor is an appropriate electrochemical tool for Azi determination in urine and Azi capsule.
