Structural and bonding analysis of PtO<inf>2</inf><sup>−</sup> anion and neutral clusters
2024, Journal of Molecular StructureEffect of PdO-PdO<inf>2</inf> core–shell nanocatalysts on hydrogen sensing performances of flame-made spinel Zn<inf>2</inf>SnO<inf>4</inf> nanoparticles
2022, Applied Surface ScienceCitation Excerpt :Thus, p-M−n (S-M−S) heterojunctions can be described using the energy band representations as presented in Fig. 12. The band gaps of Zn2SnO4 and PdO are nominally ∼ 3.6 and 2.7 eV while the related electron affinity are ∼ 4.5 and 3.1 eV, respectively [62–64]. The work functions of Zn2SnO4, PdO and metallic PdO2 are nominally ∼ 4.8, 5.4 and 3.9 eV, respectively [61,65,66] (Fig. 12(a)).
Highly sensitive and stable H<inf>2</inf> gas sensor based on p-PdO-n-WO<inf>3</inf>-heterostructure-homogeneously-dispersing thin film
2022, International Journal of Hydrogen EnergyCitation Excerpt :`Fig. 10 (a) shows the energy band diagram of PdO/WO3 heterostructure film before contact. Here, the electron affinity of PdO and WO3 are adopted as 1.7 eV [88] and 3.3 eV [89], respectively, while the band gap of PdO and WO3 are adopted as 2.2 eV [90] and 2.7 eV [91], respectively. As shown by Fig. 10 (b) & (c), after the contact, the diffusion of the holes and electrons make the heterostructure own the uniform Fermi level.

2019, Applied Surface ScienceCitation Excerpt :In addition, XPS and EDX data indicate relatively high Pd content on surface, implying that PdOx secondary crystallites mainly locate near the particle surfaces as drawn in Fig. 11(b)–(d). [9,21,39]. PdOx with Pd2+ as the main oxidation state exhibits p-type semiconductivity with a medium gap (EgPd) of 2.1 eV and a moderate electron affinity (χPd) of 1.7 eV [57,58] while In2O3 is an n-type semiconductor with a wider band gap (EgIn) of 3.0 eV and a larger electron affinity (χIn) = 3.7 eV [59]. There are mechanistic differences between the n-type and p-type materials relating to distinct pathways of conduction and gas adsorption.
Identification and characterization of two new electronic states of PtF: Analysis of the (2,1), (1,0), (0,0), (0,1), (1,2), and (0,2) bands of the [15.8 + x] Ω = 5/2 − B <sup>2</sup>Δ<inf>5/2</inf> transition
2019, Journal of Molecular SpectroscopyCitation Excerpt :The electronic landscapes of platinum containing molecules are of scientific interest not only due to the broad catalytic utility of Pt containing compounds [1,2], but also because of the difficulty in accurately describing the electronic structure theoretically due to complications from electronic correlations and relativistic effects [3]. The electronic structure of the first row main group diatomics PtB [4], PtC [5–12], PtN [9,13–15], PtO [9,16–26], and PtF [27–30] have been investigated spectroscopically, but the coverage provided by these studies is far from complete. The most recent experimental spectroscopic observation of PtF was reported by Ng et al. [30], who used a molecular beam Laser Induced Fluorescence (LIF) approach to study the electronic spectrum of PtF between 431 and 560 nm.
