“…The fabrication procedure of rGO@SnO 2 @CCs is schematically shown in Figure . After being treated with a mixture of diluted H 2 SO 4 and HNO 3 , oxygen-containing groups, such as −OH and −COOH, formed on the surface of the carbon fibers in the CC, which serve as nucleation centers for SnO 2 nanorods. ,, The formation of SnO 2 nanorods on CC is confirmed by SEM imaging. As shown in panels a and b in Figure , the SnO 2 nanorods are uniformly grown on the CC (Figure S1).…”

“…Many protocols have been proposed to suppress the volume expansion. For example, nanostructured SnO 2 with different dimensions, including one-dimensional (1D) nanorod, − two-dimensional (2D) nanosheets, − and three-dimensional (3D) hollow nanospheres, − have been employed to suppress the volume variations. In addition, porous features and voids created within SnO 2 particles can also buffer the volume variation and thus prevent the pulverization by releasing the internal stress. − The size of the SnO 2 particles is also a factor affecting its pulverization during lithiation/delithiation.…”

Volume variation, pulverization, and dead Sn accumulation that occur during lithiation/delithiation cycling are the main drawbacks of using SnO2 particles as anodes in lithium ion batteries (LIBs). In this work, we fabricated [001]-oriented SnO2 nanorods with different thicknesses (55–105 nm) on carbon cloth and sealed them with a layer of partially reduced graphene oxide (rGO@SnO2@CC). Through systematic evaluation, we found that in the thinnest SnO2 nanorods (≲55 nm), there is no dead Sn observed after 100 cycles of lithiation/delithiation in LIBs. The pulverization of the thinnest SnO2 nanorod as an anode is also greatly suppressed. In contrast, the pulverization of SnO2 nanorods and severe aggregation of dead Sn occurred in the thicker SnO2 (75 and 105 nm), which severely affects its electrochemical performance. The property of the rGO@SnO2@CC with thinner SnO2 nanorods makes it a promising anode material for LIBs. The work should also be beneficial for the development of SnO2-based anode materials for LIBs.

“…Moreover, the SnO 2 exhibited nanorod structures with ~60 nm widths and ~200 nm lengths ( Figure 3 c,d). The applied potential and the deposition time are crucial for successful formation of SnO 2 nanorods [ 43 , 44 ]. In this work, SnO 2 nanorods were synthesized from SnCl 2 on a cathode (−0.9 V vs. Ag/AgCl), and the formation of SnO 2 crystals can be attributed to electrochemical deposition of Sn(OH) 2 , followed by air oxidation during calcination, as shown below (Equations (4)–(7)) [ 45 ]:

For effective supercapacitors, we developed a process involving chemical bath deposition, followed by electrochemical deposition and calcination, to produce WO3/SnO2 nanocomposite electrodes. In aqueous solutions, the hexagonal WO3 microspheres were first chemically deposited on a carbon cloth, and then tin oxides were uniformly electrodeposited. The synthesized WO3/SnO2 nanocomposite was characterized by XRD, XPS, SEM, and EDX techniques. Electrochemical properties of the WO3/SnO2 nanocomposite were analyzed by cyclic voltammetry, galvanostatic charge-discharge tests, and electrochemical impedance spectroscopy in an aqueous solution of Na2SO4 with/without the redox-active electrolyte K3Fe(CN)6. K3Fe(CN)6 exhibited a synergetic effect on the electrochemical performance of the WO3/SnO2 nanocomposite electrode, with a specific capacitance of 640 F/g at a scan rate of 5 mV/s, while that without K3Fe(CN)6 was 530 F/g. The WO3/SnO2 nanocomposite catalyzed the redox reactions of [Fe(CN)6]3/[Fe(CN)6]4− ions, and the [Fe(CN)6]3−/[Fe(CN)6]4− ions also promoted redox reactions of the WO3/SnO2 nanocomposite. A symmetrical configuration of the nanocomposite electrodes provided good cycling stability (coulombic efficiency of 99.6% over 2000 cycles) and satisfied both energy density (60 Whkg−1) and power density (540 Wkg−1) requirements. Thus, the WO3/SnO2 nanocomposite prepared by this simple process is a promising component for a hybrid pseudocapacitor system with a redox-flow battery mechanism.

“…A piece of carbon cloth (2.5 cm × 2.0 cm, WOS 1009, CeTech, Thickness: 0.33 mm, Basic Weight: 120 g/m 2 ) was put into concentrated HNO 3 at 100 • C for 90 min. It was then cleaned with deionized water and acetone for several times, and dried at 80 • C. The SnO 2 nanorods were grown on carbon cloth (SnO 2 /CC) through a facile hydrothermal route [46]. 1.1 mol/L NaOH solution was added into 0.1 mol/L SnCl 4 •5H 2 O solution, drop by drop, under a constant stirring condition.…”

In this study, the Ag3PO4/SnO2 heterojunction on carbon cloth (Ag3PO4/SnO2/CC) was successfully fabricated via a facile two-step process. The results showed that the Ag3PO4/SnO2/CC heterojunction exhibited a remarkable photocatalytic performance for the degradation of Rhodamine B (RhB) and methylene blue (MB), under visible light irradiation. The calculated k values for the degradation of RhB and MB over Ag3PO4/SnO2/CC are 0.04716 min−1 and 0.04916 min−1, which are higher than those calculated for the reactions over Ag3PO4/SnO2, Ag3PO4/CC and SnO2/CC, respectively. The enhanced photocatalytic activity could mainly be attributed to the improved separation efficiency of photogenerated electron-hole pairs, after the formation of the Ag3PO4/SnO2/CC heterojunction. Moreover, carbon cloth with a large specific surface area and excellent conductivity was used as the substrate, which helped to increase the contact area of dye solution with photocatalysts and the rapid transfer of photogenerated electrons. Notably, when compared with the powder catalyst, the catalysts supported on carbon cloth are easier to quickly recycle from the pollutant solution, thereby reducing the probability of recontamination.
