“…The following steps occur during the template synthesis of cage‐like/hollow nanostructures: i) synthesizing template, ii) using template to create target structure, iii) removing template (if necessary) 157. Recently, one “top‐down” synthetic route has been extensively studied by using the low‐cost and highly chemically reactive Cu 2 O NCs (cubes, octahedra, and other highly symmetrical structures) as the sacrificial template, to create various hollow, non‐spherical nanostructures, including hollow metal oxides,35, 38, 45, 47, 48, 49, 52 hollow copper sulfide (Cu x S y ),93, 158, 159, 160, 161, 162 and hollow metals or alloys 134, 163, 164, 165. In this section, we summarize the recent progress in Cu 2 O sacrificial templates, and discuss the three major routes as shown in Figure 8 (galvanic replacement, the Kirkendall effect, and coordinating etching).…”

“…For instance, by employing hydrofluoric acid as a capping agent (CA), H. G. Yang et al34 were the first to obtain uniform anatase TiO 2 single crystals with a high percentage (47%) of highly reactive {001} facets, which possessed promising applications in sensors, solar cells and photocatalysis. Besides the various routes for the synthesis of NCs, several novel strategies have recently exploded by carving, modifying, or transforming the original NCs that greatly improve the catalysis and sensing performances 6, 27, 30, 33, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52. For example, X. Chen et al51 disordered the surface layers of nanophase TiO 2 by hydrogenation.…”

Facet‐Controlled Synthetic Strategy of Cu₂O‐Based Crystals for Catalysis and Sensing

Shape‐dependent catalysis and sensing behaviours are primarily focused on nanocrystals enclosed by low‐index facets, especially the three basic facets ({100}, {111}, and {110}). Several novel strategies have recently exploded by tailoring the original nanocrystals to greatly improve the catalysis and sensing performances. In this Review, we firstly introduce the synthesis of a variety of Cu2O nanocrystals, including the three basic Cu2O nanocrystals (cubes, octahedra and rhombic dodecahedra, enclosed by the {100}, {111}, and {110} facets, respectively), and Cu2O nanocrystals enclosed by high‐index planes. We then discuss in detail the three main facet‐controlled synthetic strategies (deposition, etching and templating) to fabricate Cu2O‐based nanocrystals with heterogeneous, etched, or hollow structures, including a number of important concepts involved in those facet‐controlled routes, such as the selective adsorption of capping agents for protecting special facets, and the impacts of surface energy and active sites on reaction activity trends. Finally, we highlight the facet‐dependent properties of the Cu2O and Cu2O‐based nanocrystals for applications in photocatalysis, gas catalysis, organocatalysis and sensing, as well as the relationship between their structures and properties. We also summarize and comment upon future facet‐related directions.

“…With rapid advances in chemical science, there are many nanomaterials available with well-defined sizes, shapes, crystal facets, structures and compositions. [7][8][9][10][11][12][13][14] There have been increasing efforts to design and control the interface chemistry between different types of components. This is because two-phase interfaces could render hybrid junctions with rich redox reactions, which are beneficial for enhancing the catalytic performance.…”

The fabrication of multi-component hybrid nanostructures is of vital importance because their two-phase interface could provide a rich environment for redox reactions, which are beneficial for enhancing catalytic performance. Inspired by the above consideration, strongly coupled Cu 2 O@CeO 2 core@shell nanostructures have been successfully prepared via a non-organic and clean aqueous route without using any organic additive. In this process, an auto-catalytic redox reaction occurred on the two-phase interface, followed by a triggered self-assembly process. Additionally, the size, morphology and composition of the as-obtained nanostructures can be tuned well by varying the reaction temperature, as well as the species and the amount of Cu precursors. The catalytic tests for peroxidase-like activity and CO oxidation have been conducted in detail, and the results confirm a strong synergistic effect at the interface sites between the CeO 2 and Cu 2 O components.

“…Hollow nanostructures have always been a hot topic in energy-related fields because of their large specific surface area, big interior void space and diversified building blocks [11][12][13][14]. For example, Lou et al realized the controllable synthesis of various hollow nanostructured materials, such as VO 2 hollow nanospheres [15], SnO 2 hollow nanoboxes [16] and α-Fe 2 O 3 hollow nanotubes [17]. Wang et al also developed many hollow nanospheres with multi-layered shell including Co 3 O 4 [18], α-Fe 2 O 3 [19], etc.…”

In-situ growth of ultrathin MoS2 nanosheets on sponge-like carbon nanospheres for lithium-ion batteries

Developing novel electrode materials for lithium-ion batteries (LIBs) with rapid charge/discharge capability and high cycling stability remains a big challenge to date. Herein, we demonstrate the design and synthesis of ultrathin MoS 2 nanosheets in-situ grown on sponge-like carbon nanospheres by a simple diffusion-controlled process. The unique sponge-like carbon nanosphere core can be used as "reservoir" of electrolyte by adsorbing to shorten the iondiffusion path, and meanwhile as "elastomer" to alleviate the structural change of the MoS 2 nanosheets during the charge/ discharge processes. Furthermore, the vertical ultrathin MoS 2 nanosheets with broadened interlayer space greatly enrich the electrochemical active sites. Consequently, the as-obtained MoS 2 /C nanospheres exhibit increased specific capacities at various rates with superior cycling stability compared to the MoS 2 /C floccules. It is reckoned that the present concept can be extended to other electrode materials for achieving highrate and stable LIBs.
