“…It is noticeable that the waste adsorbent may fulfill the structural requirements for Li storage in LIBs as they are capable of loading abundant antimony by inner-sphere complexation via an adsorption process, which has high chemical bond stability and large dispersion of antimony. Furthermore, the highly dispersed antimony buffers the volume expansion in the alloying process of antimony and Li . Other components in the material are also useful in LIBs, including carbon, iron oxide, and rare-earth-doped materials .…”

The development of high-capacity adsorbents is pivotal for the removal of antimonite (Sb(III)) and antimonate (Sb(V)) as priority pollutants in water. Herein, a Fe-La-doped biomass carbon adsorbent (Cs/Fe-La) was prepared for efficient removal of both Sb(III) and Sb(V). Cs/Fe-La shows excellent adsorption behavior for both Sb(III) and Sb(V) at 40 °C with a maximum capacity of 498 and 337 mg/g, respectively. Additionally, the antimony adsorption mechanism and the contribution of Cs/Fe-La composition to high capacity were analyzed based on the characterization of physicochemical analysis and adsorption studies, and the pseudo-second-order kinetic model as well as the Langmuir model fit the results well. Remarkably, considering the secondary pollution caused by direct disposal of antimony-containing waste adsorbents, an antimony-enriched waste adsorbent (Cs/Fe-La-SbO x ) was used as an anode material for a Li-ion battery. The heat-treated waste adsorbent exhibited good cycling performance with a reversible specific capacity of 833.8 mAh/g after 500 cycles. This work has demonstrated a promising pathway that can achieve the removal and sustainable utilization of antimony simultaneously by minimizing antimony contamination and maximizing the recycling of antimony-enriched adsorbents.

“…[ 4 ] Carbon nanotubes (CNT), as a typical sp 2 ‐hybridized carbon material, possess the properties of lightweight, high effective specific surface area, and excellent electrical conductivity, which is a popular catalytic support in heterogeneous catalysts. [ 5 ] The CNT‐supported metal NPs catalysts were synthesized with different approaches, such as covalent coupling, [ 6 ] non‐covalent synthesis, [ 7 ] electrochemical, [ 8 ] electroless deposition, [ 9 ] and physical or chemical vapor deposition techniques, [ 10 ] and so on. Nevertheless, the pristine CNT is proved to be too inert to stabilize or optimize metal particles.…”

Carbon‐supported metal nanocatalysts have received substantial attention for heterogeneous catalysis in industry. Hunting for suitable and impactful carbon supports that have strong interactions with metal nanocatalyst is a matter of great urgency. Herein, a well‐designed graphdiyne layer decorated on the carbon nanotubes sidewalls (CNT@GDY) serves as a novel carbon support. This unique hybrid structure effectively traps platinum and palladium atomic clusters (Pt/Pd‐ACs) with dimensions of 0.65 nm and 1.05 nm uniformly and firmly, forming novel carbon‐supported metal nanocatalysts (Pt(Pd)‐ACs/CNT @ GDY) for efficient hydrogen generation and aromatic nitroreduction, respectively. The Pt‐ACs/CNT@GDY can deliver an HER current density of 10 mA cm−2 with a small overpotential of 23 mV in 0.5 M H2SO4, showing a greatly enhanced mass activity, intrinsic activity than the commercial Pt/C catalyst. The Pd‐ACs/CNT@GDY also exhibits excellent catalytic activity and a high turnover frequency of 38.0 min−1 for aromatic nitroreduction. The carbon support turns out to possess excellent conductivity, abundant and uniform reactive sites, low redox potential, more negative surface and large specific surface area as well as a strong interaction with ACs, as anticipated in ideal supports, which can be applied in other metal‐supported catalysts.

“…Alloy-based anode materials, especially antimony, have a high theoretical specific capacity (660 mA•h•g −1 ) and a suitable working potential for application in alkali ion batteries; however, they are subject to volume expansion (up to 400%) during the charging/discharging procedure, which usually creates electrode pulverization and leads to deteriorated cycling performance and rate capability [4][5][6][7]. To address the above issues, three effective strategies are generally adopted: introduce inactive/active ingredients (Sn, Bi, Co, etc) [8][9][10] to Sb to stabilize the electrode structure; fabricate nano-sized materials (nanowire, nanofiber, nanotube) [11][12][13] to relieve the internal stress; combine Sb with a buffer substance, such as carbon materials (graphene, hard carbon, soft carbon) [14][15][16] to mitigate the volume expansion of Sb and increase the electrode conductivity. Although many Sb-based nanocomposites have been reported, problems such as the aggregation of nanoparticles and low cohesive force between the alloy and the carbon still exist.…”

Ultrafine nano-scale Cu 2 Sb alloy confined in a three-dimensional porous carbon was synthesized using NaCl template-assisted vacuum freeze-drying followed by high-temperature sintering and was evaluated as an anode for sodium-ion batteries (SIBs) and potassium-ion batteries (PIBs). The alloy exerts excellent cycling durability (the capacity can be maintained at 328.3 mA•h•g −1 after 100 cycles for SIBs and 260 mA•h•g −1 for PIBs) and rate capability (199 mA•h•g −1 at 5 A•g −1 for SIBs and 148 mA•h•g −1 at 5 A•g −1 for PIBs) because of the smooth electron transport path, fast Na/K ion diffusion rate, and restricted volume changes from the synergistic effect of three-dimensional porous carbon networks and the ultrafine bimetallic nanoalloy. This study provides an ingenious design route and a simple preparation method toward exploring a high-property electrode for K-ion and Na-ion batteries, and it also introduces broad application prospects for other electrochemical applications.
