Water electrolysis is an ideal method for industrial green hydrogen production. However, due to increasing scarcity of freshwater, it inevitable develop advanced catalysts electrolyzing seawater especially at large current density. This work reports a unique Ru nanocrystal coupled amorphous-crystal Ni(Fe)P2 nanosheet bifunctional catalyst (Ru-Ni(Fe)P2 /NF), caused by partial substitution Fe Ni atoms in , and explores its electrocatalytic mechanism density functional theory (DFT)...
Abstract Oxygen loss is a serious problem of lithium‐rich layered oxide (LLO) cathodes, as the high capacity LLO relies on reversible oxygen redox. release can occur at surface leading to formation spinel or rock salt structures. Also, lattice will usually become unstable after long cycling, which remains major roadblock in application LLO. Here, it shown that Zr doping an effective strategy retain due affinity between and O. A simple sol‐gel method used dope 4+ into LLOs adjust local...
Finding out the catalysis trend is an important prerequisite for development of advanced or untouched catalysts. Intermetallic silicides composed interstitial Si and Pt-group metals (PGMs) are currently rarely reported as hydrogen evolution reaction (HER) catalysts due to absence accessibility predictability. Herein, by theoretical calculations, we unveil activity PGM show that IrSi most efficient HER catalyst because appropriate d-band center optimal adsorption behavior. Furthermore,...
This review provides an overview of catalytic hydroconversion processes including hydrocracking, hydrogenolysis and hydrodeoxygenation for upcycling plastic wastes into fuels valuable chemicals.
High-energy-density nickel (Ni)-rich cathode materials are used in commercial lithium (Li)-ion batteries for electric vehicles, but they suffer from severe structural degradation upon cycling. Planar gliding and microcracking seeds fatal mechanical fracture, their origin remains unclear. Herein, we show that “layer-by-layer delithiation” is activated at high voltages during the charge process when “lattice collapse” (a characteristic high-voltage lattice evolution Ni-rich cathodes) occurs....
Fast-charging, non-aqueous lithium-based batteries are desired for practical applications. In this regard, LiMn
The key to realizing highly efficient hydrogen production by water electrolysis is elevate the electrocatalytic activity of oxygen evolution reaction (OER) as a rate-determining step. Herein, we demonstrate that electrochemical activation process CoP nanoflower supported on carbon cloth (CoP/CC) can remarkably reduce OER overpotential about 123 mV, which only requires an ultralow 176 mV at current density 10 mA cm–2. Correspondingly, voltage assembled CoP/CC||CoP/CC electrolyzer also greatly...
Using bifunctional silica as a catalyst for graphitization and templating agent pore-formation, high surface area are synchronously realized in porous N/P doped carbonaceous materials.
Abstract Lithium‐ion batteries (LIBs) are currently widely applied in many aspects of life, but with the development, capacity lithium‐ion can no longer meet needs. One dominant factors to restricting LIBs is cathode materials. Among derivatives spinel LiMn 2 O 4 (LMO), LiNi 0.5 Mn 1.5 (LNMO) has become one research promising materials current due its high working voltage (4.7 V) and large theoretical specific (147 mAh g −1 ). However, short cycle life LNMO during electrochemical process...
To supress Li/Ni mixing, the strategy of surface modification and Co doping is proposed. Doping trace can suppress mixing in bulk phase cathode particles, while rock-salt shell a originally containing large amount mixed rows be transformed into cation-ordered spinel layered on inside by means engineering. Simultaneously, as coating layer, Li2MoO4 nanolayer forms surface. With improved Li-ion diffusion, certain inhibitory effects voltage attenuation capacity loss are found. It shows that with...
Abstract Li–CO 2 batteries arouse great interest in the context of carbon neutralization, but their practicability is severely hindered by sluggish CO redox reaction kinetics at cathode, which brings about formidable challenges such as high overpotential and low Coulombic efficiency. For complex multi‐electron transfer process, design catalysts molecular or atomic level understanding relationship between electron state performance are essential for redox. However, little attention paid to...
Triphenylphosphine not only restricts Fe growth with 2-methylimidazole in bidirectional confinement to obtain high-density Fe–N sites, but also prevents the irregular aggregation of on carbon surface generate positive 2 P nanocrystals.
Stacking faults, as common native crystallographic planar defects, have a significant negative impact on lithium (Li) ion diffision in layered oxide cathode materials, which must be considered to design and construct high-performance Li-ion batteries. Herein, we disclose that the stacking fault is one of important factors contributing sluggish diffusion kinetics Li-rich oxides (LLOs). Multidimensional multiscale structural analyses, combined with theoretical calculations, reveal LLOs...
Owing to the interacted anion and cation redox dynamics in Li2 MnO3 , high energy density can be obtained for lithium-rich manganese-based layered transition metal (TM) oxide [Li1.2 Ni0.2 Mn0.6 O2 LNMO]. However, irreversible migration of Mn ions oxygen release during highly de-lithiation destroy its structure, leading voltage capacity decline. Herein, non-TM antimony (Sb) is pinned TM layer LNMO by a facile sol-gel method. High-resolution ex situ characterization technologies manifest that...
