Plasma electrolytic oxidation (PEO) was applied using a pulsed unipolar waveformto produce Al2O3−TiO2 composite coatings from sol solutions containing colloidal TiO2 nanoparticles. The were produced by dissolving 1, 3, and 5 g/L of potassium titanyl oxalate (PTO) in silicate solution. Scanning electron microscopy, energy dispersive spectrometry, X-ray diffraction, Raman spectroscopy to characte...

C4F7N is considered to be the most potential alternative gas for SF6. However, harmful decomposition by-products generated by discharge or overheating faults will pose threat safe operation and service life of insulated equipment (GIE). Herein, we investigated adsorption performance γ-Al2O3 on its products evaluate possibility using it as adsorbent exhaust treatment material. It found that demo...

Effective abatement of the greenhouse gas sulphur hexafluoride (SF6) waste is great importance for environment protection. This work investigates size effect and surface properties γ-Al2O3 pellets on SF6 degradation in a packed bed dielectric barrier discharge (PB-DBD) system. Experimental results show that decreasing packing improves filamentary discharges promotes ignition maintenance plasma,...

Syngas production via dry reforming of methane was conducted over 5 wt%Ni + xWO3/γ-Al2O3 (x = 1, 3, 5, 7, or 9 wt%) catalysts at 700 °C and ambient pressure for 7.5 h in a tubular fixed-bed reactor. Textural, morphological, catalytic properties were investigated relation to the weight percent tungsten trioxide loading. The physicochemical evaluated using XRD, N2-physisorption, TGA, H2-TPR, CO2-...

Chemical warfare agents (CWAs) are highly toxic and fast-acting easy to cause large-scale poisoning humans livestock after being released. The activated carbon used for CWAs adsorption has disadvantages of limited capacity, aging deactivation. Metal oxides have environmental stability, they characterized by long lasting broad spectrum when thermal catalytic decomposition. Therefore, in this stu...
