Flexible sodium-ion batteries (SIBs) have aroused great interest in energy storage devices. However, the choice of suitable anode materials is a key step application SIBs. Here, simple vacuum filtration method reported to obtain bimetallic heterojunction structure. The exhibits better performance than any single-phase material sodium storage. results show that electron rich Se site and internal electric field generated by transfer structure can provide electrochemically active areas...
Abstract The exploitation of high‐efficiency, inexpensive, as well durable electrocatalysts for the oxygen reduction reaction (ORR) is vital importance commercialization fuel cells. In this study, we prepared an efficient non‐precious ORR electrocatalyst via high‐gravity technology. results physical characterization revealed that Fe atoms could be uniformly dispersed on Fe/Co/N‐MCF catalyst X‐ray photoelectron spectroscopy demonstrated can combined with N from ZIF‐67 to form Fe‐N x...
Flexible sodium-ion batteries are considered as the most promising flexible energy storage devices due to their bendability, low cost and high safety. However, development of anode materials with rate long cycle stability is a key step in application sodium ion batteries. Here, simple vacuum filtration method reported obtain bimetallic heterojunction structure. The exhibits better performance than any single-phase material diffusion storage. results show that electron rich Se site internal...
Abstract Undoubtedly, electrochemical ammonia synthesis without carbon footprint will be an anticipated alternative to the Haber-Bosch N 2 -fixation process which is energy-intensive. Herein, durian shell derived was designed as electrocatalyst precursor, and its graphene-like morphology features unique hierarchic pore structure obtained by controlling calcination condition used trap molecules firmly convert them. Furthermore, NH 3 properties with N, S doping co-doped were systematically...
Because of its low cost and abundant sodium resource, ion batteries (SIBs) are regarded as an excellent substitute for lithium-ion (LIBs) . However, due to sluggish kinetics volume expansion, most anode materials SIBs have significant challenges in achieving high power density. Here we demonstrate that Cu 2 Se nanoarrays with three-dimensional skeleton structure defects were grown on the surface copper foam by situ selenization used high-performance binder-free anodes batteries. Thanks...
Inner design and effective regulation of interlayer are the key factors for optimizing capacity deliver. Herein, this work carries out precise on crystalline type facets orientation by using ordered guidance Bi-MOF to control metal crystal growth, preferably oriented-growth along (00l) in Bi2Se3 is realized, influence dominant-exposed Na-storage investigated. Experimental investigations first-principle calculations indicates that perfect oriented growth monocrystalline Bi2Se3, open 2D...
A novel free-standing polymeric composite membrane was developed to simultaneously achieve high energy density and mechanical robustness for osmotic generation. The is composed of a poly(vinyl alcohol) (PVA) gel down layer thin graphene/sulfonated poly(ether ether ketone) (SPEEK) top layer. PVA offers excellent stability flexibility water permeability, the SPEEK think film allows cations pass through by diffusion. As result, manages power ca. 5.89W/m 2 under salinity gradient 50 (0.5 M|0.01...
