Bio-electro-Fenton microbial fuel cells generate energy through the decomposition of organic matter by microorganisms. The generated electricity drives a Fenton reaction in a cathode chamber, which can be used for the decolorization of dye wastewater. Most of the previous works added expensive platinum catalyst to improve the electrical property of the system. In this research, aligned carbon n...

The production of bio-diesel fuels from carbohydrates is a promising alternative to fossil fuels with regard to the growing severity of the environmental problem and energy crisis. Potential bio-diesel candidates or additives, such as 5-(hydroxymethyl)-2-(dimethoxymethyl) furan (HDMF), 2-(dimethoxymethyl)-5-(methoxymethyl) furan (DMMF), and 5-(methoxymethyl)-2-furaldehyde (MMF) could be produce...

For co-processing of bio-oil and conventional fossil feed in existing refinery fluid catalytic cracking (FCC) units, little attention has been paid to the increased aromatics basic nitrogen content associated with introduction how it affects FCC performance. In this contribution, effect blending two bio-oils obtained from different treatment wheat-straw pyrolysis vapors atmospheric residue was ...

Catalytic pyrolysis of Ulva lactuca macroalgae was studied over Amberlyst-15 catalyst at temperature 400, 500, and 600 oC. The comparison between catalytic non-catalytic in the conversion determined. Intriguingly, it found that improved bio-oil production efficiency. highest yield 29.54 wt% achieved oC with presence an catalyst. Furthermore, could enhance gas by 73.88%. It be attributed due to ...

Polylactate (PLA) is synthesized as a representative bio-based polyester by the chemo-bio process on the basis of metal catalyst-mediated chemical polymerization of lactate (LA) supplied by microbial fermentation. To establish the one-step microbial process for synthesis of LA-based polyesters, we explored whether polyhydroxyalkanoate (PHA) synthase would exhibit polymerizing activity toward a ...

Terminal iron nitrides (Fe≡N) have been proposed as intermediates of (bio)catalytic nitrogen fixation, yet experimental evidence to support this hypothesis has been lacking. In particular, no prior synthetic examples of terminal Fe≡N species have been derived from N2. Here we show that a nitrogen-fixing Fe-N2 catalyst can be protonated to form a neutral Fe(NNH2) hydrazido(2-) intermediate, whic...

Chemoenzymatic dynamic kinetic resolution (DKR) of rac-1-phenyl ethanol into R-1-phenylethanol acetate was investigated with emphasis on the minimization of side reactions. The organometallic hydrogen transfer (racemization) catalyst was varied, and this was observed to alter the rate and extent of oxidation of the alcohol to form ketone side products. The performance of highly active catalyst ...

INTRODUCTION Enantioselective Catalysis Beginning with the first homogeneous asymmetric metal-catalyzed reaction performed by Noyori—a cyclopropanation—the area of enantioselective catalysis in organic chemistry has become a major topic of discussion and research. Homogeneous, asymmetry-inducing catalysts have been developed for a wide range of reactions, especially notable are those developed ...

In this researchsaccharomyces cerevisiae (baker’s yeast) was used as a cheap, readily accessible, selective, efficient, and green bio-catalyst in a chemo selective reduction of carbonyl group to hydroxyl group. In this green procedure three substrates e.g. (3-(3-nitrophenyl)aziridin-2-yl)-1-phenyl-methanone, pyruvate ester, and 2-acetyl-γ-butyrolactone were r...

Catalase is one of the most potent biocatalyst which can oxidize potentially harmful toxins. Catalase is an abundant natural enzyme which is used in food industry, analytical applications (bio sensor) and textile industry to remove pollutants because of its high activity. Since catalase has many industrial applications, immobilization of catalase in solid support makes it heterogeneous catalyst...
