Abstract The rapid development of wearable, highly integrated, and flexible electronics has stimulated great demand for on-chip miniaturized energy storage devices. By virtue their high power density long cycle life, micro-supercapacitors (MSCs), especially those with interdigital structures, have attracted considerable attention. In recent years, tremendous theoretical experimental explorations been carried out on the structures electrode materials MSCs, aiming to obtain better mechanical...
The oxygen evolution reaction (OER) is the bottleneck limiting process of water splitting. OER involves recombination from diamagnetic singlet state OH or H2O to paramagnetic triplet O2. spin conservation for oxygenated intermediates must play an important role in OER. However, dynamic mechanism magnetic field-induced polarization still its infancy. Herein, based on spin-coupling interaction iron group elements, three typical layered double hydroxides (LDHs) were constructed study...
Abstract Compressive strain, downshifting the d -band center of transition metal oxides, is an effective way to accelerate sluggish kinetics oxygen evolution reaction (OER) for water electrolysis. Here, we find that anisotropic thermal expansion can produce compressive strains IrO 6 octahedron in Sr 2 4 catalyst, thus its d- band center. Different from previous strategies create constant crystals, thermal-triggered be real-timely tuned by varying temperature. As a result strain accelerating...
Abstract 2D nanomaterials are well suited for energy conversion and storage because of their thickness‐dependent physical chemical properties. However, current synthetic methods translating materials from the laboratory to industry cannot integrate both advantages liquid‐phase method (i.e., solution processibility, homogeneity, massive production), gas‐phase high quality large lateral size). Here, inspired by Chinese Sugar Figure Blowing Art, a rapid “gel‐blowing” strategy is proposed mass...
Substantial overpotentials and insufficient unstable active sites of oxygen evolution reaction (OER) electrocatalysts limit their efficiency stability in OER-related energy conversion storage technologies. Here, a template editing strategy is proposed to graft highly catalytic species onto conductive rigid frameworks tackle this challenge. As successful attempt, two types NiO6 units layered Ni BDC (BDC stands for 1,4-benzenedicarboxylic acid) metal organic are selectively edited by chemical...
Abstract The electrochemiluminescence (ECL) is generally emitted via radiative transition of singlet or triplet excited state (S 1 T ). Herein, an ECL mechanism with the transitions both S and black phosphorus quantum dots (BPQDs) found, arginine (Arg) modification strategy proposed to passivate surface oxidation defects BPQDs, which could modulate states for enhancing efficiency BPQDs. Arg leads greater spatial overlap highest lowest occupied molecular orbitals, spectral shift transitions,...
Abstract Catalytic conversion of lithium polysulfides (LiPSs) is a crucial approach to enhance the redox kinetics and suppress shuttle effect in lithium–sulfur (Li–S) batteries. However, roles typical heterogenous catalyst cannot be easily identified due its structural complexity. Compared with distinct sites single atom catalysts (SACs), each active site (SSCs) identical uniform their spatial energy, binding mode, coordination sphere, etc. Benefiting from well‐defined structure, iron...
Metal oxides with surface protonation exhibit versatile physical and chemical properties suitable for use in many fields. Here, we develop an electrochemical route to directly protonize the physically assembled oxide particles, such as TiO2, Nb2O5, WO3, a Na2SO4 neutral electrolyte, which is result of electrochemically induced oxygen vacancies reacting water molecules. With no need electric connection among particles or between conductive substrate, follows bottom-up particle-by-particle...

A challenge is create electrochemically stable on electrodes exploit small-molecule activation. Here, a strategy protonating surface oxidation layer oxytropic alloys proposed by coordinatively unsaturated metal sites (Lewis acids) and hydroxyls bases). We find that the element electronegativity metal-hydroxyl stability...
Spin qubits constructed in endohedral fullerenes benefit from the protective shielding of carbon cage, which effectively mitigates external decoherence and enables ultralong coherence times. However, fullerene spin face challenge charge transfer complex electrical environments, such as during qubit readout or large-scale integration, can induce state modifications. In this study, we developed transistors based on Lu2@C82 observed absence parity dependence Kondo effect; result was...

Intrinsic magnetic topological insulators (MTIs) MnBi2Te4 and MnBi2Te4/(Bi2Te3)n are expected to realize the high-temperature quantum anomalous Hall effect (QAHE) dissipationless electrical transport. Extensive efforts have been made on this field but there is still lack of ideal MTI candidate with ordering ferromagnetic (FM) ground state. Here, we demonstrate a sample Mn(Bi0.7Sb0.3)4Te7 which holds coexistence FM state non-triviality. The dramatic modulation magnetism induced by charge...
Electron–hole separation is a main challenge that limits the energy efficiency of photoelectrochemical water splitting for hydrogen fuel production. Surface polaron states with an level distribution near conduction band are highly efficient charge passageways to massively accept or transfer photogenerated electrons. Here, we found via surface could be further enhanced by heating (<100 °C) accelerate electron mobility states. As result from 30 70 °C, saturated photocurrent increased about...
