Hornwort-like hollow porous MoO3/NiF2 heterogeneous nanowires as high-performance electrocatalysts for efficient water oxidation

Co3O4 Supported on β‐Mo2C with Different Interfaces for Electrocatalytic Oxygen Evolution Reaction

“…On both sides of the interface, different lattice fringes are attributed to different species: lattice fringes with crystal face spacing of 0.246, 0.288, and 0.156 nm are correspondingly attributed to (311), (220), and (511) crystal faces of Co 3 O 4 . [30] The lattice fringes of 0.260, 0.236, and 0.225 nm correspond to the (100), (002), and (101) crystal planes of β-Mo 2 C. [26] Furthermore, EDS profiles scanned along the red line in Figure S20 [42] suggesting that partial oxidation occurs on the surface of Mo 2 C-3 after loading Co 3 O 4 (Figure S21c). interface due to the strong interaction between Co 3 O 4 with a positive surface potential and Mo 2 C-3 with an opposing surface potential.…”

“…In addition, HRTEM images (Figure S21) show the crystal phase change of Mo 2 C near the interface after loading Co 3 O 4 . It is worth noting that the 0.329 nm lattice fringe around the Mo−Co interface corresponds to the (021) plane of MoO 3 , [42] suggesting that partial oxidation occurs on the surface of Mo 2 C‐3 after loading Co 3 O 4 (Figure S21c). Figure 6 displays the Zeta potential for the components of the composite samples.…”

3D Co3O4‐RuO2 Hollow Spheres with Abundant Interfaces as Advanced Trifunctional Electrocatalyst for Water‐Splitting and Flexible Zn–Air Battery

“…[38][39][40] Moreover, the rich channels favor the rapid release of generated gas bubbles, exposing abundant active sites timely. [41][42][43][44][45][46][47][48] For instance, Lee et al synthesized Ir-Co 3 O 4 @Co 3 O 4 porous-core@shell hollow sphere, and this electrocatalyst revealed excellent catalytic activity toward OER in acid media. [49] Additionally, Feng et al researched that the synthesized cactuslike NiCo 2 S 4 @NiFe LDH hollow sphere presented significant bifunctional electrocatalytic performances for both ORR and OER.…”

Electrochromic Performance and Capacitor Performance of α-MoO3 Nanorods Fabricated by a One-Step Procedure

“…MoO 3 has a wide range of applications in many fields such as electrochromics [7][8][9], photochromics [10,11], electrochemical capacitors [12,13], electrocatalytic activities [14,15], gas sensors [16][17][18][19], and lithium-ion batteries [20][21][22][23][24], which makes it a more popular transition metal oxide. Recently, the electrochromic properties of MoO 3 nanomaterials have attracted much attention.…”
