Properties of hydrothermally synthesized Zn2SnO4 nanoparticles using Na2CO3 as a novel mineralizer

Fabrication of superior α-Fe2O3 nanorod photoanodes through ex-situ Sn-doping for solar water splitting

“…To date, hematite nanostructures have been synthesized using a variety of techniques including sol-gel processing [8], electrodeposition [9,10], spray pyrolysis [11], and hydrothermal synthesis [12]. In particular, hydrothermal synthesis is simple, cost effective, and provides good control over the composition and morphology [13,14]. Elemental doping plays a critical role in improving the electrical conductivity and in enhancing the PEC performance of hematite photoanodes [5,15].…”

Chiseled Nickel Hydroxide Nanoplates Growth on Graphene Sheets for Lithium Ion Batteries

“…Compared with those of the highly crystallized Ni(OH) 2 prepared with NaOH, all the peaks of the Ni(OH) 2 prepared with Na 2 CO 3 are strictly weakened, implying the lower crystallinity of the Ni(OH) 2 . 27 Annamalai et al 42 found that when NaOH is used as the mineralizer, pH value of the solution continuously decreases due to the consumption of OH À in the hydrothermal reaction (HTR), however, as a much milder base, Na 2 CO 3 can continuously supply OH À by hydrolysis during the reaction and thus stabilizes the solution pH. In contrast to NaOH as the strong base in HTR, the milder base of Na 2 CO 3 as the mineralizer would produce a less crystalline Ni(OH) 2 phase.…”

Investigations on Structural and Optical Properties of Hydrothermally Synthesized Zn2SnO4 Nanoparticles

“…Normally NaOH was used as a mineralizer and it has some drawbacks, when the concentration of NaOH is less the major phase forms will be SnO 2 . In the meantime at higher pH value the formation of ZnO phase occurs rather than the formation of Zn 2 SnO 4 [13][14][15]. In the present work, hydrazine hydrate was used in the hydrothermally synthesized Zn 2 SnO 4 nanoparticles.…”
