We report magnetically-separable, reusable, green-synthesized Fe3O4/rGO/ZnO, as heterogeneous catalyst for photo-Fenton degradation of organic pollutants in aqueous solution under certain treatments. Fe3O4 nanoparticles was using Moringa oleifera leaf extract, while rGO synthesized utilizing Amaranthus viridis extract. Fe3O4/rGO composited sonication treatment. Afterwards, doped with ZnO various concentration ZnO. X-ray diffraction and selected area electron showed that had spinel cubic...
Abstract With increasing concerns regarding the potential health risks associated with microwave‐based technology, researchers have been actively investigating materials impressive microwave absorption properties. In this study, a synthesis and investigation of nanocomposite, named Fe 3 O 4 /MWCNT/ZnO/PANI, consisting magnetite (Fe ), multi‐walled carbon nanotube (MWCNT), zinc oxide (ZnO), polyaniline (PANI) as microwave‐absorbing material, was carried out for first time. The nanocomposite...
This work aimed to study the natural dye extracted from Indonesian wild plants (Rivina humilis L.) using different solvents.The was maceration method.Three solvents, namely, aquades, acetone, and ethanol 96%, were used extract Rivina L fruit.The absorbance spectra of recorded Ultraviolet-Visible (UV-Vis) spectroscopy.The betalain pigment revealed extract's dependence on solvent.The functional groups analyzed Fourier transform infrared (FTIR) adherence carbonyl hydroxyl FTIR indicated that...
This work aimed to observe the influence of calorific value and proximate properties in fabrication rice husk (RH) coffee shell (CS) briquettes composite.Rice husks contain cellulose, hemicellulose, lignin.These contents are necessary for adhesive bind briquette (amylose amylopectin).The raw materials were carbonized at 400 °C 60 minutes.Variations sieving size (60, 80, 100 mesh) composition ratio material CS:RH reviewed study their effect.Tests density, moisture content, volatile matter ash...
In this research, Mn and Fe-based ceramic gas sensing were fabricated characterized. This research used natural mineral which is widely available in Indonesia intended to observe the characteristics of semiconducting material. Fabricating process thick films started by synthesizing powder Fe(OH)3 oxide material using precipitation method. The deposition from method previously was calcined at a temperature 800 °C produce nanoparticle powder. Nanoparticle that contains Fe mixed with an organic...
This report aimed to know the performance of local mineral-based composite ceramic. The materials used consist Indonesian minerals, which are jarosite and manganite minerals as sources oxide iron Mangan. were synthesized using precipitation method, whereas ceramic was fabricated a screen printing method fired at 600 oC furnace. results characterizations indicate that sample forms three phases on diffraction peaks. differences in resistance values ambient ethanol environments has very...
Preliminary studies about fabrication of Mn(x)Zn(2-x)FeO4 (x = 0 dan 0.1) had been done to identify the effect adding Mn2O3 10%mol towards gas sensor sensitivity. Gas ceramics that fabricated through local nature mineral-based is Yarosite mineral. The thick film semiconductor by using Screen Printing method and firing at temperature 800 °C for 2 hours. Through electrical properties test it known materials made faster response ethanol gases rather than without materials. Thick Mn0.1Zn1.9FeO4...
<em>We reported the methylene blue (MB) degradation by photocatalysis method. This work aimed to know effectiveness of using a MgFe2O4:TiO2 composite. Synthesis composite used sol-gel We synthesized three samples with ratios between MgFe2O4 and TiO2. Those were 100:0, 50:50, 75:25, respectively. Sample (75:25) degraded MB 47.23% reaction rate 5.326 x 10-3 minute-1 under solar radiation. Whereas, without radiation, sample showed lower rate. It happened because sunlight produced photon...
