Investigation of structural, morphology, and conduction mechanism of GO–Fe3O4–TiO2 composite material
(23.08.2023)
The graphene oxide composite (GO), iron oxide (Fe3O4), and titanium dioxide
(TiO2) were prepared by the sol–gel process. The surface of GO is coated with
TiO2 and Fe3O4 nanoparticles, and the composite contains 10.26% ...
Synthesis and characterization of molybdenum trioxide with an orthorhombic crystal structure for supercritical water gasification application
(01.03.2023)
Supercritical water (SCW) catalytic gasification is promising for the production of synthetic gas from biomass. However, maintaining the activity of heterogeneous catalysts under high pressure and hydrothermal conditions ...
Evaluation of characteristics of raw tea waste‑derived adsorbents for removal of metals from aqueous medium
(01.06.2023)
Chemical modification and microwave activation are cost-effective and eco-friendly engineering methods to improve biochar’s physicochemical and adsorption performance. Therefore, a series of biochars samples was produced ...
Direct co-deposition of binder-free Cu-biochar-based nonenzymatic disposable sensing element for electrochemical glucose detection
(01.11.2023)
This work is the first attempt to incorporate biochar on a pencil graphite electrode via one-step electrodeposition as a rational route for refining a copper-based biosensor for a high-performance nonenzymatic electrochemical ...
Structural, dielectric and transport properties of NaxFe1/2Mn1/2O2 (x=1 and 2/3)
(13.06.2023)
NaxFe1/2Mn1/2O2 (x = 1 and 2/3) layered oxides were prepared by an improved solid-state synthesis method. The XRD analysis confirmed the high purity of these samples. The Rietveld refinement of the crystalline structure ...
Evaluation of iron containing biochar composites prepared by different preparation methods for H2O2 sensing
(19.10.2023)
Background
The procedures employed to prepare the ferrous biochar samples, the iron salts utilized, and their quantities have an effect on the surface characteristics of the material and the types of iron that will develop ...
The effect of microwave and ultrasound activation on the characteristics of biochar produced from tea waste in the presence of H3PO4 and KOH
(01.07.2023)
The mechanism of chemical and physical activation during biomass pyrolysis is crucial for the more effective use of biomass and the preparation of functional porous biochemical materials. In this study, raw tea waste (RTW) ...
