Comparison of characteristics of selected metallic and metal oxide nanoparticles produced by picosecond laser ablation at 532 and 1064 nm wavelengths

“…In other words, the change in laser wavelengths has a noticeable effect on the phase of the TiO 2 nanoparticles. The peak positions 2h = 37.5°and 63.3°are attributed to the anatase TiO 2 phases (004) and (204), respectively [17,18]. The peak positions 2h = 36°, 41°, 54°and 63.85°a re attributed to the rutile TiO 2 phases (101), (111), (211) and (310), respectively [17,19].…”

In addition, the peaks at 2h = 32.5°are indicative of the brookite phase of the TiO 2 nanoparticles [20,21].…”

A new copper molybdate-doped aluminium phosphate nanocomposite heterostructure for photoreduction of aqueous 2-NA and 4-NA

“…8 M x Al 1− x MoO 4 (M = transition metal) is mainly employed in catalytic applications and has exceptional electrical and magnetic properties. 9,10 Previously, Ghorai et al investigated the phase formation temperature and photocatalytic activity of M x Cr 1− x Mo x P 1− x O 4 (M = Co, Ni and Cu) toward p -nitrophenol 11 and thymol blue. 12 Now, we are very much interested in the new composition of M x Mo x Al 1− x P 1− x O 4 (M = Cu, Ni, and Co) and studying its photocatalytic activity, which has as yet not been studied in the literature.…”

Effect of Co-catalyst (CuO, CoO or NiO) on Bi2O3–TiO2 Structures and Its Impact on the Photocatalytic Reduction of 4-nitrophenol

“…Organic chemicals are essential for a great number of products of pharmaceuticals, pesticides and food additives [1]. For example, it has been proposed the reduction of 4-nitrophenol to 4-aminophenol which is used for the synthesis of different pharmaceutical products [2]. Conventional industrial routes typically require harsh operating conditions, such as high temperature and pressure [3].…”
