Effects of calcination temperature on phase formation and particle size of Zn2Nb34O87 powder synthesized by solid-state reaction

Solution Combustion Synthesis, Characterization, and Photoelectrochemistry of CuNb2O6 and ZnNb2O6 Nanoparticles

“…For both these compounds, studies oriented toward the tuning of bandgap energies (or “band engineering”) have served to open up further avenues for heterogeneous photocatalysis and PEC applications. ,− …”

Room‐Temperature Synthesis of High‐Entropy Perovskite Oxide Nanoparticle Catalysts through Ultrasonication‐Based Method

“…[1][2][3][4][5][6] HEMs are based on the premise of incorporatingm ultiple components (usually five or more) into as ingle crystal phase to attain unique combination of properties that are otherwise unattainable in conventional solid solutions. [10,12,13] Although conventional perovskites with high-surface area have been synthesized previously, [14,15] high-entropy perovskites with high surfacearea have not been reported previously to the best of our knowledge.Perovskites are an important class of materials that exhibit a wide range of functionality,m aking them desirable for use in different areas of application including heterogenous catalysis. Examples include high-entropy metal dibor-ides, [4] high-entropy nitrides, [8,9] and high-entropy metal oxides (HEMOs).…”

“…[10] More recently,J iang et al extended the HEMO study to include perovskite-type oxides with six and seven metallice lements. [10,12,13] Although conventional perovskites with high-surface area have been synthesized previously, [14,15] high-entropy perovskites with high surfacearea have not been reported previously to the best of our knowledge. Although the particle size distribution of the synthesized perovskites was not reported, several studies have demonstrated that such extreme temperatured uring the synthetic process causes coagulation of grain boundaries, leadingt ot he formation of clumps, and consequent reduction in the available surfacea rea for reactions.…”
