Activity and stability of TiO2 samples with different phase compositions in the decomposition of formaldehyde in SCW
Ateş, Ayten (ELSEVİER, 6 January )TiO2 samples with different crystal sizes and compositions were synthesized using a sol-gel method at different calcination temperatures (350–900 °C). The activity and stability of TiO2 samples were determined by the ... -
Evaluation of Stability and Catalytic Activity in Supercritical Water of Zinc Oxide Samples Prepared by the Sol–Gel Method
Ateş, Ayten; Hatipoğlu, Hakan (Springer, December 2)Nano-and micro-sized ZnO samples were synthesized by the sol–gel method. Physical and thermal stability of ZnO samples were tested in supercritical water (SCW) and supercritical water gasification (SCWG) of formaldehyde. ... -
Modification of Pore and Surface Characteristics of Biochar Produced from Raw Tea Waste
Ates, Ayten (21.05.2021)The main objective of this study is to determine the effectiveness of various activation methods on the characteristics on biochar characteristics. The feedstock for producing biochar was used raw tea waste (RTW) that ... -
Preparation and characterization of nanosized Fe3O4-biochar electrocatalysts with large surface area for H2O2 sensing
Ateş, Ayten; Oskay, Kürşad Oğuz (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 ...
