“…During our experiments, we found that natural cooling instead of fast cooling of autoclave or prolonged reaction time (24 or 48 h) gave rise to some black byproducts besides SnO 2 NSs (see Supporting Information, Figure S9) which were subsequently confirmed to be SnO by XRD (see Supporting Information, Figure S10). From the XRD results, (002) is distinctly the preferential plane, whereas (101) and (110) peaks are rather weak compared to its standard intensities. In our previous work, 96 the surface energies of SnO were calculated by first-principles total energy calculations based on density functional theory (DFT) using the Vienna Abinitio Simulation Package (VASP) code.…”

“…No other peaks are found in the XRD pattern of sample SA3. It appears that the (110) and (101) peaks are relatively broader than the other peaks, which might be linked with the possibly strained common attachment planes of {110} and {101} in the SnO 2 NSs structure. Earlier assumptions of compressive stress 56−58 must be disregarded as the stress/strain parameter obtained through Williamson−Hall plots is a rootmean-square (rms) value and cannot distinguish between compressive and tensile stress.…”

“…Meanwhile, all the socalled "clusters" experience a large volume expansion and attain better crystallinity when going from Sn 6 O 4 (OH) 4 to SnO 2 , as corroborated in their corresponding selected-area electron diffraction (SAED) patterns (lower right insets). In addition, the SAED pattern of sample SA3 (inset of Figure 3d) can be well indexed as (110), (101), (200), (211), and (301) planes of rutile SnO 2 (JCPDS card No. 41-1445), which is in good agreement with the above XRD result.…”

“…109 And this conclusion was further supported by Chang et al in the SnO 2 nanocrystalline cathode system. 110 Besides, the partial reversibility of reaction v is also widely suggested in the recent literatures of SnO 2 systems. 111−115 On this basis, we believe that the observed partial reversibility of reaction v is due to the ultrathin thickness of SnO 2 NSs.…”

“…As the reaction time is prolonged to 5 h, similar orientation of SnO 2 (101) planes were clearly detected in four areas (denoted by red circles), and the homogenously shallow contrast across these areas indicates the emergence of 2-dimensional sheets. After 6 h, the lattice fringes in Figure 3h feature highly oriented SnO 2 NSs along the [110] direction. Many crystal interfaces and dislocations are observed in the nanosheet.…”

Ultrathin SnO₂ Nanosheets: Oriented Attachment Mechanism, Nonstoichiometric Defects, and Enhanced Lithium-Ion Battery Performances

We successfully synthesized large-scale and highly pure ultrathin SnO2 nanosheets (NSs), with a minimum thickness in the regime of ca. 2.1 nm as determined by HRTEM and in good agreement with XRD refinements and AFM height profiles. Through TEM and HRTEM observations on time-dependent samples, we found that the as-prepared SnO2 NSs were assembled by “oriented attachment” of preformed SnO2 nanoparticles (NPs). Systematic trials showed that well-defined ultrathin SnO2 NSs could only be obtained under appropriate reaction time, solvent, additive, precursor concentration, and cooling rate. A certain degree of nonstoichiometry appears inevitable in the well-defined SnO2 NSs sample. However, deviations from the optimal synthetic parameters give rise to severe nonstoichiometry in the products, resulting in the formation of Sn3O4 or SnO. This finding may open new accesses to the fundamental investigations of tin oxides as well as their intertransition processes. Finally, we investigated the lithium-ion storage of the SnO2 NSs as compared to SnO2 hollow spheres and NPs. The results showed superior performance of SnO2 NSs sample over its two counterparts. This greatly enhanced Li-ion storage capability of SnO2 NSs is probably resulting from the ultrathin thicknesses and the unique porous structures: the nanometer-sized networks provide negligible diffusion times of ions thus faster phase transitions, while the “breathable” interior porous structure can effectively buffer the drastic volume changes during lithiation and delithiation reactions.

A new nitrogen‐doped ordered mesoporous carbon (N‐doped OMC) is synthesized by using an organic–inorganic coassembly method, in which resol is used as the carbon precursor, dicyandiamide as the nitrogen precursor, silicate oligomers as the inorganic precursors, and F127 as the soft template. The N‐doped OMC possesses a surface area as high as 1374 m2 g−1 and a large pore size of 7.4 nm. As an electrode material for supercapacitors, the obtained carbon exhibits excellent cycling stability and delivers a reversible specific capacitance as high as 308 F g−1 in 1 mol L−1 H2SO4 aqueous electrolyte, of which 58 % of the capacity is due to pseudo‐capacitance. The large specific capacitance is attributed to proper pore size distributions, large surface area, and high nitrogen content.

Recycled Poly(vinyl alcohol) Sponge for Carbon Encapsulation of Size‐Tunable Tin Dioxide Nanocrystalline Composites

The recycling of industrial materials could reduce their environmental impact and waste haulage fees and result in sustainable manufacturing. In this work, commercial poly(vinyl alcohol) (PVA) sponges are recycled into a macroporous carbon matrix to encapsulate size-tunable SnO2 nanocrystals as anode materials for lithium-ion batteries (LIBs) through a scalable, flash-combustion method. The hydroxyl groups present copiously in the recycled PVA sponges guarantee a uniform chemical coupling with a tin(IV) citrate complex through intermolecular hydrogen bonds. Then, a scalable, ultrafast combustion process (30 s) carbonizes the PVA sponge into a 3D carbon matrix. This PVA-sponge-derived carbon could not only buffer the volume fluctuations upon the Li-Sn alloying and dealloying processes but also afford a mixed conductive network, that is, a continuous carbon framework for electrical transport and macropores for facile electrolyte percolation. The best-performing electrode based on this composite delivers a rate performance up to 9.72 C (4 A g(-1) ) and long-term cyclability (500 cycles) for Li(+) ion storage. Moreover, cyclic voltammograms demonstrate the coexistence of alloying and dealloying processes and non-diffusion-controlled pseudocapacitive behavior, which collectively contribute to the high-rate Li(+) ion storage.
