We report the synthesis of a spectrum of highly crystalline molybdenum sulphide/oxide-based materials such as MoS₂ (2-H), MoO₂ and unique hybrid MoS₂/MoO₂ nanostructures through chemical vapour deposition (CVD). The as-fabricated samples were scrutinized with materials characterization techniques. Our results reveal that, by tuning growth parameters, different samples demonstrate unique morphologies, which can be unequivocally tied to their chemical composition. We also explore their potential application as electrochemical catalysts, which we found that in addition to using large specific surface area and conductive substrate to improve interlayer conductivity,chemical heterogeneity and efficient charge transport are also essential for good catalytic activity.

我们报告了光谱的高结晶度的硫化钼/氧化物基材料的合成，例如MoS ₂（2-H），MoO ₂和独特的混合MoS ₂ / MoO ₂通过化学气相沉积（CVD）形成纳米结构。用材料表征技术仔细检查制成的样品。我们的结果表明，通过调整生长参数，不同的样品表现出独特的形态，可以明确地与其化学组成相关。我们还探索了它们作为电化学催化剂的潜在应用，我们发现除了使用大的比表面积和导电底物来改善层间电导率之外，化学非均质性和有效的电荷传输对于良好的催化活性也是必不可少的。
