Hybrid Cu_xO–TiO₂ porous hollow nanospheres: preparation, characterization and photocatalytic properties

Abstract

A series of CuxO–TiO2 hollow nanospherical composites with different mass percents of copper element were prepared, and the composites displayed high photocatalytic activities towards acetaldehyde degradation to CO2 under visible-light irradiations.

Introduction and Advancements in Room-Temperature Ferromagnetic Metal Oxide Semiconductors for Enhanced Photocatalytic Performance

“…MOS nanoparticles (NPs), which include materials like TiO 2 , ZnO, and SnO 2 , have garnered significant attention for their intriguing blend of magnetic and charge transport properties [9,10], and the following are notable examples. TiO 2 's Special Significance: Among MOS NPs, titanium dioxide (TiO 2 ) holds a distinctive position due to its solid photocatalytic behavior and a plethora of advantages.…”

“…The process of photocatalysis-harnessing light energy to drive catalytic transformations-offers an environmentally conscious approach to the breakdown of contaminants in both water and air. Simultaneously, the manifestation of room-temperature ferromagnetism introduces a spectrum of potential technological applications, spanning spintronics and magnetic storage devices [8][9][10][11].…”

Wireframe Orbit-Accelerated Bipedal DNA Walker for Electrochemiluminescence Detection of Methyltransferase Activity

“…9 After stirring to react for 4 h, the Rub@ TiO 2 @SiO 2 NPs were centrifuged and rinsed with deionized water three times. To etch the inner SiO 2 NPs, the resultant Rub@TiO 2 @ SiO 2 NPs were dispersed in 5 mL of 1.2 M NaOH aqueous solution to stir at 60 °C for 4 h. 20 As a result, the product was isolated by centrifugation and washed with deionized water and then dispersed in 5 mL of deionized water for further use.…”

“…A reaction mixture containing l -lysine (0.097 g), TEOS (7.4 mL), and deionized water (100 mL) was stirred at 60 °C for 20 h. The solvent in the mixture was evaporated at 80 °C. The flakes obtained after solvent evaporation were heat treated at 600 °C for 6 h in air to remove organic moieties to obtain SiO 2 with diameter of 30 nm. − …”
