The OHC shows superior performance as an anode material for LIBs with a high reversible capacity (1181 mA h g<sup>−1</sup> at 0.1 A g<sup>−1</sup>) and excellent rate capability (304 5 g<sup>−1</sup>).
Recent research into graphene-based materials is largely focused on graphene quantum dots (GQDs) and their optical properties. A facile method has been developed to extract GQDs from reduced oxide (RGO) by the ozonation pre-oxide method. The as-prepared GQDs, which were 2–5 nm in diameter, exhibited strong fluorescence activity ranging ∼355 ∼440 nm. prepared possessed with yields 3.18% 9.48%. What's more, properties of could be determined tuning pH system. We speculated mechanisms ozonation,...
Strategies incorporating heterometals to introduce surface-active hydrogen (*H) have been extensively utilized enhance the electrocatalytic activity of Cu-based catalysts in nitrate reduction reaction (NitRR). However, a comprehensive understanding *H behavior and its specific impact on regulating NitRR pathway remains elusive, particularly quantitative manner. In this study, we prepared group layered double hydroxides (LDHs) as model with diverse concentrations lifetimes. Our findings...
Single-atom catalysts (SACs), specifically iron single atoms dispersed on nitrogen-doped carbon (Fe-NC), have shown promising potential in the electrocatalytic reduction of nitrate to ammonia (NitRR), but there is a lack understanding their intrinsic activity. The conventional measurements often overlook performance SACs, leading significant underestimation. This study presents an situ electrochemical probing protocol, using two poisoning molecules (SCN– and NO2–), characterize reactivity Fe...
A microwave (MW)-assisted synthesis method for preparation of fluorescent BSA-stabilized and HSA-protected gold nanoclusters (BSA–AuNCs HSA–AuNCs) has been developed. The reaction time can be shortened from tens hours to several minutes, thanks the superheating non-thermal effects MW energy. optimal experimental conditions including concentrations BSA, HAuCl4 NaOH programme are investigated in detail. as-synthesised BSA–AuNC product is well characterized by UV-vis spectroscopy, fluorescence...
A SiO2 nanoparticle decorated polypropylene (PP) separator (PP-SiO2) has been prepared by simply immersing the PP in hydrolysis solution of tetraethyl orthosilicate (TEOS) with assistance Tween-80. After decoration, thermal stability and electrolyte wettability PP-SiO2 are obviously improved. When is used for lithium–sulfur (Li–S) batteries, cyclic rate capability batteries greatly enhanced. The capacity retention ratio Li–S battery configured 64% after 200 cycles at 0.2 C, which much higher...
Abstract Absorption and fluorescence spectra of graphene quantum dots (GQDs) have been computed by using time‐dependent density functional theory (TDDFT). Different functionals, including PBE, TPSSh, B3LYP, PBE0, CAM‐B3LYP, LC‐ωPBE, tested B3LYP/6‐31G(d) has proven to be the most accurate method for our work. The bulk solvent effects toluene dichloromethane assessed polarizable continuum model (PCM). absorption wavelength GQDs in solvents is red‐shifted compared with that gas phase. Edge...

A rapid signal amplification system based on the self-replicating catalyzed hairpin assembly is reported in which two hairpins, H1 and H2, were well-designed split target/trigger DNA G-quadruplex sequences respectively integrated into H2. Target/trigger can be cyclically used this to form duplex assemblies (H1–H2), will bring fragments close-enough proximity induce formation of intact as a colorimetric readout. Similarly, reunite sequence that identical DNA; then, obtained replica also new...
A green and efficient anhydrous method was developed to synthesize nitrogen doped carbon dots (N-CDs) on a large-scale, the N-CDs exhibited excellent reversible pH-sensitive property.
Boosting sufficient Li+ ion mobility in Li4Ti5O12 (LTO) is crucial for high-rate performance lithium storage. Here, an ultrafast charge storage oxygen vacancy two-dimensional (2D) LTO nanosheet was successfully fabricated through a one-pot hydrothermal method. The selectively doped Al3+ into octahedron Li+/Ti4+ 16d sites not only provide bulk and appropriate distorted TiO6 octahedra to facilitate ions diffusion, but also serve as "pillar" stabilize the Ti–O framework. lowers diffusion energy...
