Material design and synthesis have made tremendous impacts in the scientific community by unleashing a material's true potential via enhanced properties and applications. Over the years, advanced synthetic strategies have emerged and have been expanded to not only control the size and shape of nanoparticles but also to control the preferential growth of surface facets, paving the way for new materials with facet-dependent properties. Metal oxide (111) facets as compared to their potentially more stable counterpart facets (e.g., ( 100), ( 110)) have recently exhibited enriched chemical properties owing to their unique surface arrangement. As a result, metal oxide (111) faceted surfaces have been used in applications such as catalysis, sorbents, batteries, etc. This review aims to provide a perspective on the synthetic processes utilized to expose (111) surfaces and the governing factors/ synthetic parameters that expose them across various metal oxides of different crystal structures as well as some of their applications.

“…The (Mo/β-Mo 2 C)@C nanorods were produced by a lowtemperature magnesiothermic reduction (MTR) [16,37,38]. Typically, 300 mg of sodium bicarbonate (NaHCO 3 ) and 100 mg of MoO x -EDA were mixed, and then 25, 50, and 100 mg of magnesium powders were introduced to the mixture and transferred to a half-sealed stainless steel can placed at the center of a quartz tube in a tube furnace.…”

To explore low-cost, high-efficiency, and noble-metal-free catalysts for electrocatalytic water splitting in both acidic and alkaline media, the metal-metal carbide Janus hierarchical structure comprising Mo and β-Mo2C embedded on a carbon layer (Mo/β-Mo2C)@C is synthesized by a hydrothermal reaction and subsequent low-temperature magnesium thermic process. Systematic characterization by XRD, XPS, Raman scattering, and SEM/TEM reveals the successful formation of metallic Mo and β-Mo2C nanoparticles. The synthesized (Mo/β-Mo2C)@C has a large specific surface area and boasts highly efficient hydrogen evolution reaction activity including low overpotentials of 152 mV and 171 mV at a current density of 10 mA cm-2 and small Tafel slopes of 51.7 and 63.5 mV dec-1 in acidic and alkaline media, respectively. In addition, the catalyst shows outstanding stability for 48 hours in both acidic and alkaline media. The excellent catalytic activity originates from more active sites and greater electron conductivity bestowed by the carbon layer, which also improves the long-term stability in both acidic and alkaline solutions.

“…[19][20][21] Metal oxide nanoparticles such as CuO, MgO, CeO 2 , SnO 2 , TiO 2 , ZnO and WO 3 are broadly used for photocatalysis, which is due to their high stability, appropriate energy bandgap, ion production, free radical generation and enhanced e-h pair lifetime properties. [22][23][24][25][26] Their non-toxic nature in water, abundance, cost-effectiveness and sustainability in various environmental elds make metal oxides suitable candidates for photocatalysts. 27 Among the metal oxides, SrO can be used for biomedical, cancer therapy, sensor, supercapacitor and catalyst applications.…”
