Abstract In this study, novel polyaniline-coated perovskite nanocomposites (PANI@CoTiO 3 and PANI@NiTiO ) were synthesized using an in situ oxidative polymerization method evaluated for the photocatalytic degradation of Rhodamine B (RhB) a persistent organic pollutant. The displayed significantly enhanced efficiency compared to pure perovskites. 1%wt achieved impressive 94% RhB under visible light after 180 min, while 1wt.% PANI@CoTiO3 reached 87% UV same duration. X-ray diffraction (XRD)...
The treatment of sewage wastewater generates a substantial amount sludge, which poses significant ecotoxicological and environmental challenges. Managing this sludge is critical, as traditional disposal methods carry risks: agricultural use can lead to contamination, while landfill raises concerns about solid waste management the preservation sites. Our research focuses on converting urban into activated carbon. We employed various techniques characterize NaOH-activated biochar, including...
The present study investigates the effect of manganese incorporation on structural, dielectric, and waste bioconversion LiTaO3 ferroelectric material. Conventional solid-state synthesis techniques were utilized to produce powder samples, which subsequently analyzed using room-temperature X-ray diffraction (XRD) for phase identification. analysis revealed that material forms a continuous solid solution within composition range 0 25 mol% (Mn), exhibiting R3c-Rombohedral symmetry. Thermal...
Biodiesel is a potential alternative for fossil fuel. However, its large-scale application held up by the disadvantage of homogenous process, scarce availability raw materials and production cost, which higher than diesel. In this work, biodiesel was carried out using both refined used cooking oils. The process investigated in batch reactor, presence CaO as heterogeneous catalyst prepared calcination natural Waste Grooved Razor Shell (GRS). Characterizations X-Ray Diffraction (XRD) Thermal...
The paper presents the combined effect of pozzolan, as an alkaline volcanic rock, and perlite, acidic in synthesis geopolymers. perlite proportion varied between 0% 50% by weight. A mixture sodium silicate (Na2SiO3) hydroxide (NaOH) was used activator. on physio-mechanical properties synthesized geopolymers evaluated compressive strength (Rc), P-wave velocity (Vp), bulk density (D), porosity (P). microstructural aspects have been explored X-ray Diffractometry (XRD), Infrared Spectroscopy...
Microbial fuel cells (MFCs) provide new opportunities for the sustainable production of energy, converting organic matter into electricity through microorganisms.
