Tin dioxide nanomaterial-based photocatalysts for nitrogen oxide oxidation: a review
Beilstein J. Nanotechnol. 2022, 13, 96–113, doi:10.3762/bjnano.13.7
- of Sn at the surface of SnO2 plays a role in the reversible transformation of the surface composition from Sn4+ cations to Sn2+, which leads to active centers in the surface chemical process [48]. Moreover, the OVs in SnO2 often appear when it is synthesized by chemical methods such as sol–gel
TiO2/GO-coated functional separator to suppress polysulfide migration in lithium–sulfur batteries
Beilstein J. Nanotechnol. 2019, 10, 1726–1736, doi:10.3762/bjnano.10.168
- scan rate of 0.1 mV s−1. All the CV curves exhibit two cathodic peaks, which can be ascribed to the transformation of elemental sulfur, S8, into soluble high-order polysulfides and then into Li2S and Li2S2 [41]. On the other hand, the anodic peaks can be assigned to the reversible transformation of
Novel reversibly switchable wettability of superhydrophobic–superhydrophilic surfaces induced by charge injection and heating
Beilstein J. Nanotechnol. 2019, 10, 840–847, doi:10.3762/bjnano.10.84
- responsiveness that was superhydrophobic in acidic and neutral water but superhydrophilic in an ordinary environment. Lei et al. [17] reported pH-responsive switching between superhydrophobicity and superhydrophilicity for high oil–water separation efficiency. Lv et al. [18] achieved a reversible transformation
- reversible transition of graphene surface water droplets from hydrophobic to hydrophilic was studied at a shutdown voltage [24]. Nbelayim et al. [25] achieved the reversible transformation of graphene from hydrophobic to hydrophilic driven by a direct-current voltage. Cui et al. [26] tested droplets of
Ultrasonication-assisted synthesis of CsPbBr3 and Cs4PbBr6 perovskite nanocrystals and their reversible transformation
Beilstein J. Nanotechnol. 2019, 10, 666–676, doi:10.3762/bjnano.10.66
- perovskite nanocrystals (PNCs) and their reversible transformation. The as-prepared CsPbBr3 PNCs and Cs4PbBr6 PNCs exhibit different optical properties that depend on their morphology, size, and structure. The photoluminescence (PL) emission and quantum yield (QY) of the CsPbBr3 PNCs can be tuned by changing
- water. The mechanism of this transformation between the CsPbBr3 PNCs and Cs4PbBr6 PNCs and their morphology change are studied, involving ions equilibrium, anisotropic growth kinetics, and CsBr-stripping process. Keywords: CsPbBr3 PNCs; Cs4PbBr6 PNCs; polar-solvent-free; reversible transformation
- PNCs were successfully converted to Cs4PbBr6 PNCs through a “ligand-mediated transformation” method with the addition of oleylamine (OAm) [24]. Udayabhaskararao’s group showed the reversible transformation from CsPbX3 to Cs4PbX6 through the ratio of oleic acid (OA) to OAm in a Brønsted acid–base
Review: Electrostatically actuated nanobeam-based nanoelectromechanical switches – materials solutions and operational conditions
Beilstein J. Nanotechnol. 2018, 9, 271–300, doi:10.3762/bjnano.9.29
- densities (1–10 nA/nm2) a Joule heating induced rise of temperature (in the range of 1000 °C) may trigger a change of chemical composition of the material. For example, for Mo6S3I6 bundles, a non-reversible transformation to Mo was reported, as a result of evaporation of S and I [100]. This effect may be
Fabrication of CeO2–MOx (M = Cu, Co, Ni) composite yolk–shell nanospheres with enhanced catalytic properties for CO oxidation
Beilstein J. Nanotechnol. 2017, 8, 2425–2437, doi:10.3762/bjnano.8.241
- oxidation of low-concentration of CO [4], selective reduction of NOx with NH3 [5], and oxidation of volatile organic compounds (VOC) [6][7]. The catalytic activity of CeO2 is believed to originate from the reversible transformation between Ce4+ and Ce3+ and affected by various structural factors [8][9][10
