The efect of microwave and ultrasound activation on the characteristics of biochar produced from tea waste in the presence of H3PO4 and KOH
(Springer, 14.08.2021)
The mechanism of chemical and physical activation during biomass pyrolysis is crucial for the more efective use of biomass
and the preparation of functional porous biochemical materials. In this study, raw tea waste (RTW) ...
Preparation and characterization of nanosized Fe3O4-biochar electrocatalysts with large surface area for H2O2 sensing
(Elsevier, Nisan 2022)
A nanoscale Fe3O4-biochar (Fe-BC) composite material was prepared using hazelnut shell (HNS) biochar and
FeCl2. Biochar was prepared by phosphoric acid (H3PO4)-assisted pyrolysis (BCA) and H3PO4 + microwave
(MW)-assisted ...
Mechanochemical Pretreatment for Waste-Free Conversion of Bamboo to Simple Sugars: Utilization of Available Resources for Developing Economies
(05.01.2022)
In this work, mechanochemical pretreatment of Bambusa vulgaris is evalu-ated for waste-free production of renewable sugars for subsequent fermen-tation. After a 60 min mechanochemical pretreatment followed by enzyme ...
Optimization of Paracetamol and Chloramphenicol Removal by Novel Activated Carbon Derived from Sawdust Using Response Surface Methodology
(01.02.2023)
Paracetamol (PCT) and chloramphenicol (CPL) can have unfavorable impacts on human health, as well as on natural ecosystems. These substances contribute to the aquatic environment’s contamination and disturb the performance ...
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 ...
