“…In recent years, a number of anode materials including carbon based materials, Si based materials, metal salts as well as transitional metal oxides, have been widely investigated as the potential anode materials for LIBs. In particular, transitional metal silicates such as Zn 2 SiO 4 ,, Mn 2 SiO 4 , Co 2 SiO 4 and Fe 2 SiO 4 , have attracted extensive attentions for lithium ion battery anode owing to their high capacity, low cost and eco‐friendliness. Amongst them, Fe 2 SiO 4 , a promissing materials with orhorhombic α‐Fe 2 SiO 4 (Abbreviated as Fe 2 SiO 4 ) phase and cubic γ‐Fe 2 SiO 4 structures, has received special attentions, due to its widespread availability as the most abundant minerals and importance in geophysics and materials science.…”

The first kind of mesoporous Fe 2 SiO 4 /C nanocomposites (MFS-1) were synthesized from the nano-SiO 2 with a surface area of 137 m 2 ⋅g À 1 and the second kind of mesoporous Fe 2 SiO 4 /C nanocomposites (MFS-2) were prepared from the nano-SiO 2 with a surface of 325 m 2 ⋅g À 1 . XRD results indicate that α-Fe 2 SiO 4 crystal phase appear in the two samples. SEM proves that the particle size of MFS-2 (30-40 nm) is smaller than that of MFS-1 (40-60 nm). TEM further proves Fe 2 SiO 4 nanoparticles are homogeneously dispersed in the carbon networking of MFS-2.Pore structure analysis reveals that the specific surface area of MFS-2 (136 m 2 ⋅g À 1 ) is evidently larger than that of MFS-1 (116 m 2 ⋅g À 1 ), revealing the pore properties of mesoporous Fe 2 SiO 4 /C nanocomposites can be well controlled by using silica with different surface area. The above characters make MFS-2 exhibit a high initial reversible capacity of 667 mAh⋅g À 1 at 0.1 C, excellent rate capability (282 mAh⋅g À 1 at 10 C) and improved cycling stability (606 mAh⋅g À 1 at 1 C after 100 cycles).

“…With respect to the latter issue, the problem with covalent functionalization is that robust treatment protocols, usually involving strong, destructive acids (such as HNO 3 and H 2 SO 4 as illustrative examples), can lead to a loss of not only the structural integrity but also, consequentially, the favorable electronic properties of the CNTs, 127 all of which could dramatically reduce both activity and long-term stability. 128 Hence, our preference revolved around a less intrusive and less damaging noncovalent, physical sonication-mediated approach. To highlight that both types of attachment methodologies are functionally equivalent, it is interesting to observe that the CVs of Pt NWs supported onto not only covalently functionalized COOH-terminated MWNTs (Figure 11A) but also analogous noncovalently functionalized COOH-derivatized MWNTs (Figure 11B) were essentially identical in nature.…”

“…However, a key difference in our studies, as compared with the previous work, was that we explored the impact of modifying not only the terminal ligand moiety but also the attachment approach.

Fuel cells (FCs) convert chemical energy into electricity through electrochemical reactions. They maintain desirable functional advantages that render them as attractive candidates for renewable energy alternatives. However, the high cost and general scarcity of conventional FC catalysts largely limit the ubiquitous application of this device configuration. For example, under current consumption requirements, there is an insufficient global reserve of Pt to provide for the needs of an effective FC for every car produced. Therefore, it is absolutely necessary in the future to replace Pt either completely or in part with far more plentiful, abundant, cheaper, and potentially less toxic first row transition metals, because the high cost-to-benefit ratio of conventional catalysts is and will continue to be a major limiting factor preventing mass commercialization. We and other groups have explored a number of nanowire-based catalytic architectures, which are either Pt-free or with reduced Pt content, as an energy efficient solution with improved performance metrics versus conventional, currently commercially available Pt nanoparticles that are already well established in the community. Specifically, in this Perspective, we highlight strategies aimed at the rational modification of not only the physical structure but also the chemical composition as a means of developing superior electrocatalysts for a number of small-molecule-based anodic oxidation and cathodic reduction reactions, which underlie the overall FC behavior. In particular, we focus on efforts to precisely, synergistically, and simultaneously tune not only the size, morphology, architectural motif, surface chemistry, and chemical composition of the as-generated catalysts but also the nature of the underlying support so as to controllably improve performance metrics of the hydrogen oxidation reaction, the methanol oxidation reaction, the ethanol oxidation reaction, and the formic acid oxidation reaction, in addition to the oxygen reduction reaction.

“…Also, other shapes are derived by a related process, but with variation in pH [10][11]. In similar hydrothermal method, the spindle-like Zn2SiO4 product was easily acquired by involving zinc nitrate and sodium silicate in the presence of sodium hydroxide after heating at 220 °C [12]. Additional techniques were developed using solidstate reaction between SiO2 and ZnO or other precursors to form Zn2SiO4 at high temperature, i.e., the use of colloidal gel prepared from zinc nitrate and silica sol, heated at 1000 -1400 °C [13].…”

A new approach was developed for the green synthesis of ZnO-SiO2 composite and Zn2SiO4 using zinc nitrate and sustainable silica precursor, oil palm (Elaeis guineensis) leaves (OPL). The products were synthesized at two different reaction temperatures through calcination in an open-air furnace at 500 and 1000 °C, respectively, and further identified with an X-ray diffractometry (XRD) analysis. The composite indicated by the presence of peaks at 2θ = 31.7°, 34.4°, 36.3°, 47.6°, 56.6°, and 62.9°, corresponds to ZnO and also revealed amorphous SiO2 at 2θ = 21°. Conversely, Zn2SiO4 was acknowledged at 2θ 25.6°, 31.50°, 34.0°, 39.5°, 48.9°, 56.5° and 65.6°, with crystalline silica at 2θ = 21.9°. The results showed the morphology of both products exhibited similar agglomeration based on scanning electron microscopy (SEM) analysis. Both products (ZnO-SiO2 composite and Zn2SiO4) possessed the capacity to degrade methylene blue (MB) under sunlight irradiation with efficiency of 85.9% and 69.3%, respectively.
