Lattice Distortion in Hollow Multi‐Shelled Structures for Efficient Visible‐Light CO2Reduction with a SnS2/SnO2Junction

“…This lattice distortion can be also reflected from X-ray absorption near-edge structure (XANES) spectroscopy by measuring the Sn K-edge.The normalized Sn K-edge XANES and the variations of k 3 -weighted Fourier transformed magnitudes of Sn K-edge EXAFS spectra of quadrupleshelled SnS 2 -SnO 2 (4S-SS) HoMSs after various sulfuration period are shown in the Supporting Information, Figure S5 and Figure 2a.A sd epicted in Figure 2a,p eaks at 1.63 [9] and 2.09 [10] corresponded to the Sn À Oa nd Sn À S, respectively.T he intensity of former peak decreased, and the latter peak increased with the increasing of sulfuration time, indicating the content raising of SnS 2 .M oreover,t he peaks around 3.37 correspond to Sn À Sn of SnS 2 of 4S-SSHoMSs, which shift slightly to the Rdirection compare to the standard SnS 2 ,i ndicating the extend of SnÀSn bond after forming the hetero-structure.A nd the 12 hs ulfuration (4S-SSHoMSs-12 h) shows the maximum shift, proving that the highest ratio of interface are structured.…”

Applications of Voltammetry in Lithium Ion Battery Research

“…Li ion battery has the best performance among rechargeable batteries that are currently in commercial use and is widely used in portable products such as mobile phones, laptops, power tools, and electric vehicles. In addition, due to technological advances, the performances required for Li ion batteries such as high capacity long cycle life have been gradually enhanced [1][2][3][4][5][6]. Looking at the Li ion batteries, electrochemical reactions take place in the electrodes, and even in the electrolyte.…”

Lattice Distortion in Hollow Multi‐Shelled Structures for Efficient Visible‐Light CO2Reduction with a SnS2/SnO2Junction

“…The normalized Sn K‐edge XANES and the variations of k 3 ‐weighted Fourier transformed magnitudes of Sn K‐edge EXAFS spectra of quadruple‐shelled SnS 2 ‐SnO 2 (4S‐SS) HoMSs after various sulfuration period are shown in the Supporting Information, Figure S5 and Figure a. As depicted in Figure a, peaks at 1.63 Å and 2.09 Å corresponded to the Sn−O and Sn−S, respectively. The intensity of former peak decreased, and the latter peak increased with the increasing of sulfuration time, indicating the content raising of SnS 2 .…”
