Abstract
This paper mainly focuses on the application of nanostructured MoO3 materials in both energy and environmental catalysis fields. MoO3 has wide tunability in bandgap, a unique semiconducting structure, and multiple valence states. Due to the natural advantage, it can be used as a high-activity metal oxide catalyst, can serve as an excellent support material, and provide opportunities to replace noble metal catalysts, thus having broad application prospects in catalysis. Herein, we comprehensively summarize the crystal structure and properties of nanostructured MoO3 and highlight the recent significant research advancements in energy and environmental catalysis. Several current challenges and perspective research directions based on nanostructured MoO3 are also discussed.
Highlights
In the 21st century, the impending depletion of fossil fuels and urgent environmental concerns are among the most challenging issues
Photocatalysis is the acceleration of a photoreaction rate in the presence of a catalyst, and it is a green and sustainable catalytic technology that has been widely studied for chemical synthesis, water treatment, environmental cleaning, and self-cleansing processes [92]
The MoO3 mainly consists of four phases: orthorhombic (α), monoclinic (β), hexagonal (h), and high pressure monoclinic (ε)
Summary
In the 21st century, the impending depletion of fossil fuels and urgent environmental concerns are among the most challenging issues. The search for developing superior nanostructured catalysts is a sustainable alternative Noble metal catalysts such as Pt, Pd, Rh, and Au exhibit high activity, to tackle the energy and environmental challenges. The noble metal catalysts are impacted by their scarcity, high cost, and relatively low stability, which impede their general use in large scale applications. Molecules 2020, 25, 18 applications in energy and environmental catalysis on account of their relatively low cost, high activity, and stability [9,10,11,12]. The superiorities of low cost, chemical stability, high theoretical specific capacity (1117 mA·h/g), and the environmentally friendly nature make nanostructured MoO3 exceptional electrode materials for rechargeable batteries capacitors [13,18]. We provide a brief perspective on the current challenges and opportunities for effectively utilizing nanostructured MoO3 and taking full advantage of MoO3 in constructing highly efficient materials
