“…The diffraction pattern is in good agreement with the database for YSZ (JCPDS 301468), matching well with that of the cubic fluorite-type phase (space group Fm 3 m ) commonly found for fully yttria-stabilized zirconia . However, with XRD alone, it is difficult to distinguish between cubic and tetragonal YSZ phases as they share common diffraction patterns . Thus, Raman spectroscopy is used as a complementary characterization to confirm the crystalline nature of Y 2 O 3 –ZrO 2 .…”

We demonstrate a symmetric supercapacitor by using yttria-stabilized zirconia (YSZ) as the electrolyte and silicon carbide nanowires (SiC NWs) as the electrode. The stacked symmetric SiC NWs/YSZ/SiC NWs supercapacitors exhibit excellent thermal stability and high areal capacitance at temperatures above 300 °C. The supercapacitor functions well at a record high temperature of 450 °C, yielding an areal capacitance of 92 μF cm(-2) at a voltage scan rate of 100 mV s(-1). At this temperature, it is also capable of withstanding current densities up to 50 μA cm(-2), yielding a maximum areal power density of 100 μW cm(-2). Good cycling stability is demonstrated with a capacitance retention of over 60% after 10,000 cycles at the operation temperature of 450 °C and a scan rate of 200 mV s(-1).

Designing water-stable and sustainable adsorbents for wastewater management has gained significant importance nowadays. This paper reports coprecipitation-induced rapid synthesis of a highly porous ternary metal oxide (TMO), its characterization, and efficient removal of malachite green (MG) from simulated water by a batch method. The material was characterized by the Brunauer−Emmett−Teller (BET) surface area, scanning electron microscopy (SEM), powder X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, point of zero charge (pH zpc ), and chemical analysis. With a high surface area of 185.04 m 2 /g, TMO offers an excellent adsorption capacity of 133 mg/g under optimized conditions. pHdependent adsorption was seen, and maximum adsorption was attained at the neutral condition, i.e., pH 7. Intraparticle diffusion (R 2 = 0.998) and a combined Langmuir and Freundlich isotherm model (R 2 = 0.987−0.998) best describe the adsorption pathway, suggesting that the process undergoes diffusive mass transfer and multilayer adsorption. The adsorption mechanism is proposed to be a combination of electrostatic interaction and hydrogen bonding. Thermodynamic parameters suggest a spontaneous (ΔG, −3.335 kJ/mol), feasible, and exothermic (ΔH, −8.436 kJ/mol) process. The low activation energy (3.459 kJ/mol) suggests a physisorption process. The material can be regenerated up to 83% by 0.1 M hydrochloric acid and reused for up to four cycles without significant loss of activity.

“…In both catalyst samples, a series of well‐defined peaks can be identified at 2θ = 30.06°, 34.73°, 50.16°, 59.8°, and 62.59°, which can be assigned to the diffractions of the (101), (110), (200), (211), and (202) crystalline planes of cubic phase ZrO 2 (JCPDS card no. 49‐1642), respectively 30 . Peaks related to NiO were not visible at the catalyst loading of 5% ( see Figure S1), however, increasing the catalyst loading to 10% the peaks were detected at 2θ = 27.32°, 43.3°, and 62.8°, which can be assigned to the diffractions of the (111), (200), (220) crystalline planes of cubic NiO 31,32 (JCPDS card no.…”

Pyrolysis of waste polystyrene to generate fuel was carried out to yield pyrolysis oil. For the first time, NiO deposited over ZrO2 carrier as catalyst, was deployed and evaluated in the catalytic pyrolysis. Catalysts based on different loading (2, 5, 10, and 15%) of NiO deposited over ZrO2 carrier were prepared by solution combustion synthesis and tested toward screening of catalytic pyrolysis of PS in semi batch reactor. Based on conversion, yield of oil and low styrene monomer content, the catalytic performance with different loadings was evaluated and optimized. Furthermore, the oil obtained from the best catalysts were analyzed using GC–MS for carbon number distribution, depolymerization reactions, and diesel fuel generation. These catalysts were also characterized using X‐ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), pyridine FTIR, and scanning electron microscopy (SEM) techniques. As compared to thermal pyrolysis, the catalytic pyrolysis process was found to be highly selective toward diesel like fuel generation with minimum styrene monomer formation. Also, 2 and 10% NiO catalyst showed the best catalytic performance in pyrolysis process that could be ascribed to the presence of Lewis and Brönsted acid sites resulting in selectivity for C16 carbon number, diesel fuel generation, and depolymerization reactions.
