Quick synthesis of homogeneous Nb2O5 nanorod arrays via a microwave-assisted hydrothermal method

Nb2O5 nanoparticles obtained by microwave assisted combustion synthesis under different conditions

“…The results from TEM and XRD are in agreement. In addition, the results from TEM confirmed the obtaining of nanoparticles with diameter between 5-110 nm, similar to others results in the literature [8][9][10][11][12][13] in which a wide size distribution is noted similarly to MACS. However, MACS is more advantageous due to the shorter time necessary for the formation of nanosized and crystalline particles, without the additional steps that are required for other synthesis, especially for the C2 and C3 compositions that presented a narrower size distribution of particles.…”

“…In the last decades, new methods to obtain nanoparticles have been developed to improve optical, electrical, magnetic and chemical properties as well as to reduce production time and costs. Currently, several methods are used to produce niobium pentoxide nanoparticles, such as sol-gel [8][9][10], polymeric precursor [10], hydro-or solvo-thermal methods [11][12][13]. In general, these methods need additional washing, calcination and post-heat treatments to obtain pure and crystalline materials [8][9][10][11][12][13].…”

Facile Synthesis of Uniform Mesoporous Nb2O5 Micro-Flowers for Enhancing Photodegradation of Methyl Orange

“…Previous studies have indicated that morphologies of catalysts have a significant impact on its performance. Up to now, various interesting morphologies of Nb 2 O 5 nanostructures, such as nanowires [ 11 ], nanobelts [ 19 ], nanorods [ 20 ], nanotubes [ 21 ], hollow nanospheres [ 22 ], nanoplates [ 23 ], have been synthesized. For instance, Zhao et al fabricated Nb 2 O 5 nanorods which have higher activity (99%) in the photodegradation of methylene blue than nanospheres (40%) attribute to the higher intensity of the 001 crystal plane after 90 min [ 24 ].…”
