“…The corresponding intensity ratio of I D / I G is calculated to be 0.99, [17] indicating the graphitic nature of PC. No visible peaks corresponding to Co 3 O 4 species are observed in the XRD pattern of Co 3 O 4 /PCÀ H that may because of the uniform dispersion and small size of the Co 3 O 4 NPs, [18] which is consistent with the TEM observation. The surface composition and valence state of Co 3 O 4 /PCÀ H were further characterized by XPS.…”

Small metal oxide nanoparticles (NPs) that possess abundant accessible active areas and optimal geometric/electronic structures show great promise in electrochemical detection of hydrogen peroxide (H 2 O 2 ) but remain a synthetic challenge. Herein, a simple adsorption-annealing synthetic strategy is employed for ultrasmall Co 3 O 4 NPs using the confinement of carbon nanopores in porous carbon (PC). The characterization results indicate that Co 3 O 4 NPs with an ultrafine diameter of 3.01 nm are well distributed on PC (Co 3 O 4 /PCÀ H) with high density because of the carbon nanopore confinement of the support. The achieved Co 3 O 4 /PCÀ H can be used as an excellent electrocatalyst for H 2 O 2 detection, with a high sensitivity of 332 μA mM À 1 cm À 2 , a low detection limit of 1.2 μM, and an excellent linear detection ranges from 0.04 to 20 mM. This catalyst can also be employed for sensing H 2 O 2 in real samples. The large specific surface area and unique morphology and structure of Co 3 O 4 /PCÀ H contribute to the high performance for H 2 O 2 detection. Provided herein is a facile but efficient strategy for the synthesis of enzyme-free electrochemical H 2 O 2 sensor for analytical applications.

“…The Co 3 O 4 nanoribbon arrays were synthesized by a facile hydrothermal process and a subsequent annealing treatment, [38][39] which were easier to be obtained than the Ni 2 P electrode from the aspect of experimental operation. X-ray diffraction (XRD) was employed to confirm the crystalline phase of the Co 3 O 4 deposit.…”

Coupling the H 2 evolution reaction in water with thermodynamically favorable organic oxidation reactions is highly desirable, because it can enhance the energy conversion efficiency compared with electrocatalytic water splitting, and produce value-added chemicals instead of O 2 in the anodic reaction. Herein, Co 3 O 4 nanoribbon arrays in situ grown on nickel foam (Co 3 O 4 @NF) was employed as an effective electrocatalyst for the selective oxidation of tetrahydroisoquinolines (THIQs). Various value-added semidehydrogenation products including dihydroisoquinolines with electro-deficient or -rich groups could be obtained with moderate yields and faradaic efficiencies. Benefitting from the rich surface active sites of Co 3 O 4 @NF, a twoelectrode (Co 3 O 4 @NF j j Pt) electrolytic system drove a benchmark current density of 10 mA cm À 2 at a cell voltage as low as 1.446 V in 1.0 M KOH aqueous solution containing 0.02 M THIQ, which was reduced by 174 mV in comparison with that of overall water splitting.

“…Moreover, Huang and co-workers [36] developed a one-step method by simple vulcanization of Cu foil to in situ form a modified layer of Cu 2 S nanoparticles, where the nucleation overpotential of Li was significantly lowered with the assistance of the Cu 2 S lithophilic layer. Very recently, 1D/2D substances have been anchored on the 3D hosts [37][38][39][40][41][42][43][44][45]. Sun et al [39] introduced tightly arranged ZnO nanorods on Ni foam, where the high aspect ratio of these nanorods offered a large electrode surface area, leading to further reduced local current density and efficient suppression of Li dendrites.…”

“…The Cu@Sn nanocones can facilitate uniform electric field and the dispersion of current density to inhibit Li dendrites. Huang et al [44] [45] demonstrated a facile strategy for coating uniform aluminum-zinc oxides (AZO) layers on Cu foams, which improved the lithiophilic property of Cu foams and achieved uniform Li deposition. It should be noted that the size of these lithiophilic species is no more than 1000 nm, which may collapse due to the repeated alloying/de-alloying reaction in the process of Li plating/stripping [35].…”

LixCu alloy nanowires nested in Ni foam for highly stable Li metal composite anode

et al. 2021

Porous metal architectures are widely adopted as three-dimensional conducting scaffolds for constructing Li metal composite anodes, whereas their macropores hinder their practical application due to limited surface area and large pore size of few hundred micrometers. In this work, a network of Li x Cu solid solution alloy nanowires is in situ formed via infiltrating molten Li-Cu alloy into Ni foam and subsequent cooling treatment, whereby a three-component composite anode consisting of Li metal, Li x Cu alloy, and Ni foam is fabricated. The Li x Cu nanowires nested as secondary frame split the macropores into micropores, enlarging the active surface area and inducing uniform Li deposition significantly. The lithiophilicity of the alloy wires and the shrunken void size built by the hierarchical architecture can further tune the nucleation and growth behavior of Li. The multiscale synergetic effect between the primary and secondary scaffold guarantees the composite anode sheet with extraordinarily long-term cycling stability even under high current rates.
