Synthesis of Bi 2 O 3 -doped and TiO 2 -doped porous Lava for photocatalytic studies

One step to stabilize calcium sodium phosphate crystals acting as photocatalysts embedded in a glass matrix

“…Next, previous research has presented TiO 2 -and Bi 2 O 3 -doped porous lava composites prepared as catalysts on glass substrates by the dip-coating method to solve this problem. A 40% methylene blue (MB) solution was degraded within 1 h under UV light [9]. Furthermore, TiO 2 coated on glass ber cloth was synthesized by the sol-gel method.…”

Development of pristine and Au-decorated Bi2O3/Bi2WO6nanocomposites for supercapacitor electrodes

“…Bi 2 O 3 has been studied widely as a material for supercapacitor electrodes because of its oxide-ion conductivity, band-gap and high electrochemical stability. [7][8][9][10][11] Due to its ferroelectric and oxide-ionconductive properties, Bi 2 WO 6 exhibits good physical and chemical properties, and luminescence activity. 12 It belongs to the Aurivillius phase crystal family in which the perovskite layers of (WO 4 ) 2 lie between (Bi 2 O 2 ) 2+ layers.…”

Effects of Sintering Temperature on Crystallinity, Morphology, and Photocatalytic Activity of Bi2O3

“…Over the past few years, research on semiconductor-based photocatalysis has been gaining interest as it has wide-ranging applications, from gas sensor, electrochromic material, solar energy conversion, optoelectronic devices, to optical layers [1][2] [3]. Traditional photocatalytic materials such as TiO 2 , ZnO, and BiPO 4 have incredible photocatalytic performance under ultraviolet light irradiation but their energy gaps are too wide to be able to absorb visible light [3][4] [5].…”

“…Over the past few years, research on semiconductor-based photocatalysis has been gaining interest as it has wide-ranging applications, from gas sensor, electrochromic material, solar energy conversion, optoelectronic devices, to optical layers [1][2] [3]. Traditional photocatalytic materials such as TiO 2 , ZnO, and BiPO 4 have incredible photocatalytic performance under ultraviolet light irradiation but their energy gaps are too wide to be able to absorb visible light [3][4] [5]. This is quite a drawback as UV only makes up 5 % of the total sunlight reaching the Earth [6] [7].Therefore, researchers try to develop photocatalytic materials that can be activated by visible light such as Bi 2 O 3 with an energy gap of 2.8 eV [8][9] [10].…”
