The poor stability of Ru-based acidic oxygen evolution (OER) electrocatalysts has greatly hampered their application in polymer electrolyte membrane electrolyzers (PEMWEs). Traditional understanding performance degradation centered on influence bias fails describing the trend, calling for deep dive into essential origin inactivation. Here we uncover decisive role reaction route (including catalytic mechanism and intermediates binding strength) operational catalysts. Using MRuOx (M = Ce4+,...
Catalyst/support interaction plays a vital role in catalysis towards acidic oxygen evolution (OER), and the performance reinforcement is currently interpreted by either strain or electron donation effect. We herein report that these views are insufficient, where dynamic of interface under potential bias must be considered. Taking Nb2 O5-x supported iridium (Ir/Nb2 ) as model catalyst, we uncovered migration species between IrOx during OER. Direct spectroscopic evidence combined with...
Advanced optimization strategies for Ir-based oxygen evolution catalysts include morphological regulation, heteroatomic doping, crystal phase control, and support introduction.
Abstract Solar‐driven evaporation is a promising strategy to relieve fresh water stress in the world. For an evaporator, it necessary be equiped with novel photothermal conversion materials and regulate heat energy loss solar‐driven generation process for efficiency. Herein, eutectic gallium‐indium (EGaIn)/polyaniline (PANI) complex (EP) cellulose nanocrystals (CNCs) are explored as light absorber broadband absorbing dispersant particles uniformity. Based on Bénard–Marangoni effect,...
Highly-active and low-cost bifunctional electrocatalysts for oxygen reduction evolution are essential in rechargeable metal-air batteries, single atom catalysts with Fe-N-C promising candidates. However, the activity still needs to be boosted, origination of spin-related catalytic performance is uncertain. Herein, an effective strategy regulate local spin state through manipulating crystal field magnetic proposed. The atomic Fe can regulated from low intermediate high spin. cavitation dxz...
Ru species encapsulated in HCSs can effectively break the homogeneous electron distribution and generate abundant active sites for HER.
Repetitive DNA sequences accounts for over 80% of maize genome. Although simple sequence repeats (SSRs) account only 0.03% the genome, they have been widely used in genetic research and breeding as highly informative codominant markers. The genome-wide distribution polymorphism SSRs are not well studied due to lack high-quality genome data.In this study, using data from de novo-sequenced genomes five representative inbred lines, we revealed that were more densely present telomeric region...
Abstract Engineering an electrocatalytic anode material to boost reaction kinetics is highly desirable for the anodic oxygen evolution (OER), which major obstacle high efficiency water electrolysis. Here, we present a novel kind of Zn-doped Co 3 O 4 hollow dodecahedral electrocatalyst. Abundant vacancy defects are introduced due incorporation Zn 2+ , beneficial OH − adsorption and charge transfer during OER process. Moreover, increase in surface area caused by advanced structure porous...
The oxygen evolution reaction (OER) is the efficiency-determining half-reaction process of high-demand, electricity-driven water splitting due to its sluggish four-electron transfer reaction. Tremendous effects on developing OER catalysts with high activity and strong acid-tolerance at oxidation potentials have been made for proton-conducting polymer electrolyte membrane electrolysis (PEMWE), which one most promising future hydrogen-fuel-generating technologies. This review presents recent...
Developing cost-effective electrocatalysts for oxygen reduction reaction (ORR) is of great importance to improve the performance metal–air batteries. Herein, a CoNi alloy encapsulated in an N-doped carbon framework (CoNi@NC) with high saturation magnetization (89.1 emu g–1) prepared by nanoalloying, and external magnetic field employed directly enhance ORR CoNi@NC. The electronic structure CoNi@NC greatly optimized electron cloud redistribution spin-state adjustment, leading Pt/C-comparable...
Blue perovskite light-emitting diodes (PeLEDs) have attracted enormous attention; however, their unsatisfactory device efficiency and spectral stability still remain great challenges. Unfavorable low-dimensional phase distribution defects with deeper energy levels usually cause disorder, substantially limiting the device's performance. Here, an additive-interface optimization strategy is reported to tackle these issues, thus realizing efficient spectrally stable blue PeLEDs. A new type of...
Inorganic nanocrystals catalysts with a high proportion of high-energy surfaces can bring about performance for catalysis and has been an important research topic in the past decades. Gamma alumina is one most inorganic oxides used as solid acids or catalytic support many more industrial catalysts. However, preparation gamma mainly external never reported because it complicated crystal structure. We demonstrate here depth new-type γ-alumina material from systematic investigation, which...
The successful deployment of proton-exchange membrane water electrolyzers (PEMWEs) relies on the development an active and durable electrocatalyst for anodic oxygen evolution reaction (OER). Although rutile IrO2 shows excellent durability due to its stable crystal structure, it suffers from unsatisfactory activity. Here, we report a partial Sn substitution strategy trigger lattice reactivity toward boosted OER. similar structures SnO2 promote uniform incorporation into IrO2, thus retaining...
