Greatly efficient chemical processes are customarily based upon a catalyst activating the process pathway to achieve higher yields of product with desired specifications. Catalysts capable achieving good performance without compromising green credentials pre-requisite for development sustainable process. In this study, CeO2 nanoparticles were tested their catalytic activity two different config...

This paper reports the synthesis of CeO2/ZrO2 nanocomposite by wet chemical method using cationic surfactant (CTAB). The properties of the obtained nanocomposites were analysed by X-ray diffraction (XRD), Fourier transform infrared (FTIR), scanning electron microscoy (SEM), transmission electron microscopy (TEM), UV-Diffuse Reflectance Spectroscopy (UV-DRS) and photoluminescence (PL) spectrosco...

Low-cost metal oxide sensors are highly attractive for emerging applications such as breath analysis. Particularly promising p-type that can operate at low temperatures, a key requirement compact and low-power devices. To date, however, these lack sufficient sensitivity, selectivity, humidity robustness to fulfil stringent requirements faced in real applications. Herein, flame-made sensor (oper...

A low-concentration cobalt (∼6 at%) and manganese (∼3 at%) bimetallic oxide catalyst supported on ceria nanorods (CoMnOx/CeO2), as well as its related single metal oxide counterparts (CoOx/CeO2 and MnOx/CeO2) was synthesized via a deposition-precipitation approach. The fresh samples after air-calcination at 400 °C were tested under the reaction conditions of CO oxidation, and showed the followi...

Copper oxide (CuO)-decorated cerium oxide (CeO₂) nanoparticles were synthesized and used to detect glucose non-enzymatically. The morphological characteristics and structure of the nanoparticles were characterized through transmission electron microscopy, X-ray photoelectron spectroscopy, and X-ray diffraction. The sensor responses of electrodes to glucose were investigated via an electrochemic...

To evaluate the significance of reverse osmosis (RO) and nanofiltration (NF) surface morphology on membrane performance, productivity experiments were conducted using flat-sheet membranes and three different nanoparticles, which included SiO2, TiO2 and CeO2. In this study, the productivity rate was markedly influenced by membrane surface morphology. Atomic force microscopy (AFM) analysis of mem...

A photothermal catalytic system comprising Cu/CeO2 was applied to the reaction between NO, CO and H2O for production of NH3 under visible-light irradiation. High NO conversion (94.4%) selectivity (66.5%) were achieved over in presence at 210 °C. Visible light further improved (97.7%) (69.1%). The quasi-situ EPR in-situ DRIFTS results indicated that initially reacts with form an HCO3* intermedia...
