    <dcterms:abstract xml:lang="eng">Molybdenum oxide (MoO&lt;sub&gt;3&lt;/sub&gt;) is an appropriate electrode material for vast applications such as gas sensing, catalyst, and energy storage devices. Its high oxidation states provide the possibility for ion intercalation and de-intercalation to the electrode material, which is truly advantageous for supercapacitor application. Herein, we report about reduced vertically aligned α-MoO&lt;sub&gt;3&lt;/sub&gt; nanoblades on conducting substrates via a post-treatment in reduced gas environments (H&lt;sub&gt;2&lt;/sub&gt;, N&lt;sub&gt;2 &lt;/sub&gt;and vacuum) to tune their conductivity by introducing oxygen vacancies. These α-MoO&lt;sub&gt;3&lt;/sub&gt; nanoblades were further carbonized through decomposition of glucose as a carbohydrate material to obtain binder-free carbon coated vertically aligned α-MoO&lt;sub&gt;3 &lt;/sub&gt;electrode. As a binder-free supercapacitor negative electrode, the vacuum treated α-MoO&lt;sub&gt;3&lt;/sub&gt; electrode showed the highest specific capacitance (39.8 mF cm&lt;sup&gt;−2&lt;/sup&gt;), as compared to that achieved by N&lt;sub&gt;2&lt;/sub&gt; and H&lt;sub&gt;2&lt;/sub&gt; treated samples (29.2 mF cm&lt;sup&gt;−2&lt;/sup&gt; and 24.5 mF cm&lt;sup&gt;−2&lt;/sup&gt;, respectively). Besides, the vacuum annealed electrode also maintained around 76.4% of its initial specific capacitance value after 10,000 cycles indicating a more stable electrochemical performance of such electrode. An asymmetric device 3D-MnO&lt;sub&gt;2&lt;/sub&gt;//α-MoO&lt;sub&gt;3&lt;/sub&gt; was assembled and it attained maximum specific capacitance value of 37.5 mF/cm&lt;sup&gt;2&lt;/sup&gt; at current density value 1.5 mA cm&lt;sup&gt;− 2&lt;/sup&gt; and maximum energy density value of 16.875 µWh cm&lt;sup&gt;-2&lt;/sup&gt; at power density value of 675 µW cm&lt;sup&gt;-2&lt;/sup&gt;. The results demonstrate that the proposed hybrid synthesis approach is very promising for preparation of binder-free materials for high-performance supercapacitors.</dcterms:abstract>
