“…Copper oxides with TiO2 are mentioned to give greater catalytic ability and greater photocatalytic efficacy. Several investigations have investigated the detection of toxic substances from industrial activities (e.g., xylene, dyes, phenol, and pesticides) through the use of homogeneous photocatalytic processes using constant UV radiation [19,20]. With respect to the presence of compatible functional groups, the Cytrus aurantium juice was reported to contain 86% of phenolic acids out of total phenolic compounds.…”

Green synthesis methods using plants have many advantages such as time-saving, chemical-free, and negative effects on the environment. So, extracted Citrus aurantium juice was used to synthesize green CuO/TiO2 and(G- CuO/TiO2) nanocatalyst which was characterized by XRD, SEM, EDX, FTIR, BET, and ZP and utilized in the degradation of methylene blue (MB) under UV lamps and dark environments. The ANOVA program was used to maximize the photodegradation efficiency (%) of (G-CuO/TiO2) on the MB dye. The four independent variables: Initial dye concentration (10-50 mg/L), pH (3-9), adsorbent dose (200-1000 mg/L), and contact time (30-90 min) served to the model of the photodegradation efficiency (%). The ANOVA results confirmed the high significance of the regression model while the predicted values of the photodegradation efficiency (%) of MB were in good agreement with the corresponding experimental ones. Optimized conditions for the maximum photodegradation efficiency (98.6%) by (G- CuO/TiO2) NPs were the initial dye concentration (10.93 mg/L), pH (8.87), adsorbent mass (986.43 mg/L), and contact time (89.08 min). The validity of the quadratic model was examined, and found in good agreement with the experimental values. Results demonstrated that (G-CuO/TiO2) could be a promising photocatalyst in the degradation of MB dye. Copyright © 2023 by Authors, Published by BCREC Group.

“…TiO2 is an n-type metal oxide material with a wide band gap. TiO2 nanomaterials are widely applied as photocatalysts [1][2][3][4], gas sensors [5][6][7][8], and solar cells [9]. The most common reasons for using these materials are because they have chemical stability, are environmentally inert, and are relatively inexpensive to synthesize.…”

The morphology of TiO2 nanoparticles deposited on a QCM sensor is crucial in its mechanical loading. Different heating treatments transform the morphology of TiO2 nanoparticles, affecting the loading and hence shifting the resonant frequency and changing the impedance QCM value. In this research, the deposition of TiO2 nanoparticles was carried out above QCM using the ultrasonic spray pyrolysis (USP) technique with variations in calcination temperature of 200, 230, and 250 °C. The analysis results show that the increase in the agglomeration and particle size causes an increase in the inertial mass of TiO2 nanoparticles. HIGHLIGHTS The size of TiO2 agglomerates and their particles increases as the calcination temperature is raised Higher calcination temperature resulted in a larger frequency shift of the QCM oscillation due to the layer inertial mass increase Larger TiO2 nanoparticle size significantly increases the layer’s resistance, contributing to higher impedance GRAPHICAL ABSTRACT
