Oxygen vacancy-rich, Ru-doped In₂O₃ultrathin nanosheets for efficient detection of xylene at low temperature

Abstract

The xylene sensing performance of In2O3 has been enhanced greatly by doping ruthenium into In2O3 nanosheets at low working temperature.

High-Index-Faceted Ni3S2 Branch Arrays as Bifunctional Electrocatalysts for Efficient Water Splitting

“…However, these methods require high-temperature treatment or the use of polluted thiourea or trithiocyanuric acid. Moreover, the high-temperature treatment may cause the coverage or loss of the active sites of Ni 3 S 2 [22][23][24][25]. In this context, a facile and green low-temperature synthesis method for Ni 3 S 2 electrocatalysts is highly desirable.…”

2D Materials Based on Main Group Element Compounds: Phases, Synthesis, Characterization, and Applications

“…[58] In 2 O 3 nanosheets have been prepared in multiple steps by combining hydrothermal and calcination techniques. [59,60] Their phases can be cubic or rhombohedral, which depends on the conditions during the preparation of InOOH. [59][60][61] In general, cubic-phase nanosheets are obtained with a standard hydrothermal operation.…”

[59][60][61] In general, cubic-phase nanosheets are obtained with a standard hydrothermal operation. [60] However, with the help of oxalic acid, rhombohedral InOOH is first formed and then transferred into rhombohedral-phase In 2 O 3 after calcination.…”

Facile synthesis of In2O3 nanoparticles with high response to formaldehyde at low temperature

“…Doping is one of the effective strategies. Wang et al successfully obtained Ru‐doped ultrathin In 2 O 3 nanosheets which could improve the response and selectivity to xylene. They explained that the aliovalent doping could increase the chemisorbed oxygen on the surface of In 2 O 3 and the selective catalysis of Ru could improve the sensing performance.…”
