Graphene oxide (GO), a 2-dimensional (2-D) monolayer of graphite, has drawn lot importance due to its accessibility and material compatibility. It can be produced by mechanically stirring or sonicating graphite exfoliate it into layered sheets. Due high stability, 2-D planar structure, huge surface area, easy chemical adaptation via functionalities, efficient loading with many biomolecules, optical, electrical, mechanical capabilities, GO derivatives are quickly emerging as the most intensely studied carbon-based materials in number fields. In this review, we provided thorough overview GO, synthesis pristine GO-based composites well their applications field biodiesel synthesis, adsorption, photodegradation, electrochemical along biological significance antimicrobial efficiency. Owing distinctive features, garnered interest realm catalyst. The process transesterification using supported catalyst is highlighted herein. Similarly, adsorption photodegradation several organic dyes effluents also discussed article. Finally, derived relation attractive trends highlighting future scope commercial implications.

Renewable and clean energy sources must replace conventional ones due to the dangerous effects of fossil fuel pollution. The impact incorporating hydrogen TiO2 nanoparticles into Soybean biodiesel its CRDI engine performance was assessed in this study. For operations, a 10 L/min flow 75 ppm nanoparticle also used. Experiments comparing diesel engines running on those with B15 mix (75% 15% biodiesel) found that latter had better performance, combustion behaviour inclusion both gas cenoxite oxide. Brake consumption 16.12% lower brake thermal efficiency 3.53% than at 80% loading condition. By mixture, we were able reduce CO emission by 30%, HC 50%, smoke 42%. On other hand, comparisons showed an 12.15% rise NOx. A produced 9% greater in-cylinder pressure 7% higher HRR. More power from are outcomes blend's low ignition delay period under full load conditions. This experimental work has paved path for run is hydrogen-enriched combined nanoparticles.

Biodiesel presents a sustainable alternative to fossil fuels, yet traditional homogeneous catalysts like sodium and potassium hydroxide face challenges with separation reuse. Calcium oxide (CaO) is an effective heterogeneous catalyst for biodiesel production, but its chemical instability under reaction conditions restricts long-term performance. This study introduces MOF-mediated synthesis (MOFMS) of catalysts, specifically CaO@ZnO ZnO@CaO nanocomposites, from inexpensive non-toxic metal salts linkers in water. Comprehensive characterization techniques, including XRD, FT-IR, BET, FE-SEM, ICP, CO2-TPD, were employed analyze these catalysts. When applied production soybean oil at ambient temperature pressure, achieved impressive conversion rates 99% 92%, respectively, within 25 min. Both maintained their activity over six utilization cycles, Ca²⁺ leaching remaining below 4% (2% ZnO@CaO) after the sixth run. These results provide valuable insights into preparation control, enhancing reusability production. Future research should aim improve stability investigate performance various feedstocks, evaluate feasibility industrial applications.

Os catalisadores desempenham um papel fundamental na aceleração da velocidade de uma reação química sem serem consumidos no processo, o que pode aumentar significativamente a rentabilidade produção. O objetivo deste trabalho foi realizar revisão bibliográfica abrangente, com intuito apresentar as principais técnicas utilizadas síntese heterogêneos. A pesquisa realizada por meio levantamento informações em base consolidada dados científicos, plataforma ScienceDirect. materiais ativos predominantemente empregados estudo foram óxido cálcio (CaO), níquel (NiO), zinco (ZnO), potássio (K₂O) e magnésio (MgO). Quanto aos suportes, os mais utilizados incluíram carvão ativado, alumina, zeólita, biochar, sílica, nanotubos carbono, grafeno algumas peneiras moleculares, como SBA-15. Portanto, métodos impregnação, especialmente via úmida, são amplamente nas pesquisas analisadas, destaque para processo hidrotérmico combinado outras técnicas.
