Abstract Room‐temperature sodium–sulfur batteries are potential candidate for sustainable large‐scale energy storage systems due to their high density and low cost. However, the shuttling effect of high‐order polysulfides (Na 2 S n , 4 < ≤ 8) usually leads rapid capacity fading, while reaction kinetics low‐order 1 4) slow. In this work, microporous‐mesoporous carbon derived from mangosteen peels is reported as cathode materials RT Na–S batteries. The designed micro‐mesoporous structure...
A monomolecular layer model of the surface phase microdroplets was proposed, and exact expression for Tolman length derived in this paper. The lengths water, n-pentane, n-heptane were calculated by expression, values are quite agreement with experimental values. By use Gibbs-Tolman-Kening-Buff equation, relationship between microdroplet tension radius is obtained, predicted agree well simulated results show that there an obvious effect size (or nanoparticles) on tension, decreases decreasing...
An equation for a phase transition in dispersed system has been proposed, and the applications of various kinds transitions have discussed. The determinate relation between interfacial tension radius droplet derived by monolayer model. Applying fusion relation, melting temperatures Au Sn nanoparticles calculated, predicted are good agreement with available experimental data. research results show that equations can be applied to predict systems explain phenomenon metastable states; size...
Considerable unique chemical properties of nanoparticles are related to their surface thermodynamic which mainly depend on sizes. Herein, the theoretical relationships between partial molar as well and size were derived, respectively. It was found that ratio corresponding for spherical is 3:2 during dissolution process. In experiment, standard equilibrium constants nanovaterite with different sizes obtained by determining conductivities in distilled water at temperatures. Then, calculated,...
Numerous oxidation problems of nanoparticles are often involved during the preparation and application nanomaterials. The rate nanomaterials is much faster than bulk materials due to nanoeffect. Nanosized zinc sulfide (nano‐ZnS) oxygen were chosen as a reaction system. influence regularities discussed essence was elucidated theoretically. results indicate that particle size can remarkably kinetics. constant order increase, while apparent activation energy preexponential factor decrease with...
Melting phase transitions of nanoparticles are often involved in the preparations, research studies, and applications nanomaterials. However, because changing melting temperature during process, current relations thermodynamic properties fail to accurately describe their actual behaviors. In this study, accurate between integral enthalpy entropy size with different shapes (sphere, rod, wire, regular polyhedrons) were derived for first time through designing a thermochemical cycle....
The kinetic parameters for the chemical reaction of nano-NiO different particle sizes with aqueous sodium bisulfate solution were determined; additionally, influence size on studied and discussed. results show that: there are clear effects rate constant, order, apparent activation energy pre-exponential factor; thus constant order increase, factor decrease, decrease diameter; logarithm preexponential factor, energy, exhibit a linear relationship reciprocal diameter respectively. bases role...
The desorption kinetics of nanocatalysts which is significantly influenced by particle size has crucial effects on catalytic performances. Herein, the activation energy (Ed) and pre-exponential factor (A) for CO2 nano-CeO2 with different sizes were obtained temperature-programmed desorption. Meanwhile, we found that a significant effect surface basicity. Ed, A, basicity discussed, as well relations between results indicate decreasing, strength, amount basic sites increase, ln are linearly...
