Aqueous Zn-ion batteries (AZIBs) and hybrid supercapacitors (AZHSCs) are considered promising energy-storage alternatives to Li-ion due the attractive merits of low-price high-safety. However, lack suitable cathode materials always hinders their large-scale application. Herein, amorphous K-buserite microspheres (denoted as K-MnOx ) reported for both AZIBs AZHSCs, mechanism is systematically revealed. It found that composed rich units, which can irreversibly be transformed into Zn-buserite...
Reactions with the OH radical are expected to be dominant removal processes for gas-phase polychlorinated dibenzo-p-dioxins and dibenzofuran (PCDD/Fs). The OH-initiated atmospheric chemical reaction mechanism kinetics of 2,3,7,8-tetrachlorinated (TCDF) researched using density functional theory canonical variational transition state theory. TCDF ensuing reactions including bond cleavage furan ring, O(2) addition or abstraction, dechlorination process, bimolecular TCDF-OH-O(2) peroxy NO,...
Abstract Developing high‐performance platinum (Pt) single atom catalyst with maximum metal‐atom‐utilization efficiency is of significance for water electrolysis, which demonstrates enormous potentials toward hydrogen evolution reaction (HER). In addition to stably immobilizing Pt atoms on a support material, it highly desired elaborately tailor their coordination environments achieving optimized HER performance. this work, general strategy reported develop advanced catalysts immobilized...
The polyimide support can decrease thermodynamic barriers and enrich local H 3 O + concentration for the supported Ir catalysts, enhancing OER kinetics.
An efficient synthesis of bifurans via dimerization cyclopropenes has been successfully developed using a copper-promoted cycloisomerization and palladium-catalyzed cascade. These novel bifuran structures possess interesting optoelectronic properties.
ZnWO 4 hierarchical hexangular microstars (HHMs) composed of crossed microplatelets were synthesized by a two‐step hydrothermal reaction without using any surfactants. The homogeneous HHMs characterized TEM/SEM and XRD to reveal the structural features crystallographic phase. On basis analysis time‐dependent evolution HHMs, mechanism in‐situ formation fusion, wherein morphology, components, phase changed, is proposed explain process 3D hexagonal structures. Furthermore, calcined evaluated as...
The design of hybrid structures for catalysts toward alkaline hydrogen evolution reaction (HER) is a significant strategy to promote its kinetics. Herein, we synthesize cubic CoSe2 and Co(OH)2 (c-CoSe2@Co(OH)2) from the self-reconstruction flower like Co0.85Se via simple hydrothermal method accompanied by addition NaOH. This conducive distinct enhancement in HER catalytic activity, featuring lower overpotential 156 mV at current density 10 mA cm−2 than that (288 mV). integrative techniques...
Herein, a novel PrGO–MnO x microsphere cathode material is developed for aqueous zinc ion batteries. It reveals the phase transformation of a-MnO into highly active amorphous Zn-buserite upon initial cycles, enabling excellent Zn-storage.
Abstract Hydrogen attracts researchers′ attention because its combustion products are very clean and will not pollute the environment. Electrocatalytic water splitting is a sustainable hydrogen energy production technology, which splits into oxygen. In electrocatalytic splitting, high activity catalysts can reduce potential barrier of catalytic reaction speed up reaction, among transition metal alloy have attracted extensive in application electrocatalysis due to their excellent...
Transition-metal chalcogenides (TMC) have been widely studied as active electrocatalysts toward the hydrogen evolution reaction due to their suitable d-electron configuration and relatively high electrical conductivity. Herein, we develop a feasible method synthesize an orthorhombic phase of CoSe2 (o-CoSe2) from regeneration Co0.85Se, where temperature plays key role in controlling structure transformation. To best our knowledge, this is first report about synthetic route for o-CoSe2. The...
Selecting the QoS-optimized software-as-a-service (SaaS) from a large number of services with same functionality and different Quality Service (QoS) is still hot issue. Massive QoS feedback forms big data, which exhibits ambiguity randomness increasing uncertainty service selection. Starting characterization Uncertain Big data-driven Efficient SaaS Decision Making Method (UBQoS_ESDM) proposed. The method firstly utilizes cloud model to portray in order solve problem inaccurate description...
How to make full use of IaaS resources while guaranteeing the quality service conditions is one main issues facing resource allocation. However, current allocation schemes at and PaaS levels do not consider uncertainty SaaS user access (i.e., demand), availability, provider revenue. For existing cloud configuration levels, randomness (resource demand) supply applications, as well revenue application providers, are considered enough, optimal strategy with uncertain demand for providers...
