However, tuning &lt;span class=&quot;hitHilite&quot;&gt;the&lt;/span&gt; plasmon resonance &lt;span class=&quot;hitHilite&quot;&gt;of&lt;/span&gt; 2D semiconductors and integrating with another material or semiconductor for various applications, such as solar light harvesting, remains a challenge. Herein, we designed a simple and attractive method, which facilitates &lt;span class=&quot;hitHilite&quot;&gt;the&lt;/span&gt; diffusion &lt;span class=&quot;hitHilite&quot;&gt;of&lt;/span&gt; oxygen &lt;span class=&quot;hitHilite&quot;&gt;from&lt;/span&gt; &lt;span class=&quot;hitHilite&quot;&gt;the&lt;/span&gt; graphene oxide (GO) layers &lt;span class=&quot;hitHilite&quot;&gt;of&lt;/span&gt; &lt;span class=&quot;hitHilite&quot;&gt;the&lt;/span&gt; MoS2/GO (MG) composite to oxidize &lt;span class=&quot;hitHilite&quot;&gt;the&lt;/span&gt; MoS2 layers significantly due to thermal treatment under inert atmosphere. This is &lt;span class=&quot;hitHilite&quot;&gt;the&lt;/span&gt; key step &lt;span class=&quot;hitHilite&quot;&gt;in&lt;/span&gt; &lt;span class=&quot;hitHilite&quot;&gt;the&lt;/span&gt; formation &lt;span class=&quot;hitHilite&quot;&gt;of&lt;/span&gt; MoS2/MoO3-x/RGO (MMR) (x = 0, 0.5, and 1, and all stoichiometries co-exist), due to disproportionation &lt;span class=&quot;hitHilite&quot;&gt;of&lt;/span&gt; MoS2/GO, with bulk heterojunctions among &lt;span class=&quot;hitHilite&quot;&gt;the&lt;/span&gt; components. &lt;span class=&quot;hitHilite&quot;&gt;The&lt;/span&gt; observed behavior is attributed to &lt;span class=&quot;hitHilite&quot;&gt;the&lt;/span&gt; oxidation &lt;span class=&quot;hitHilite&quot;&gt;of&lt;/span&gt; Mo4+ cations (&lt;span class=&quot;hitHilite&quot;&gt;of&lt;/span&gt; MoS2) to higher oxidation states &lt;span class=&quot;hitHilite&quot;&gt;in&lt;/span&gt; MMR (Mo(5+ )and Mo6+ &lt;span class=&quot;hitHilite&quot;&gt;of&lt;/span&gt; MoO3-x), which also alters &lt;span class=&quot;hitHilite&quot;&gt;the&lt;/span&gt; valence-band electronic structure and work function &lt;span class=&quot;hitHilite&quot;&gt;of&lt;/span&gt; &lt;span class=&quot;hitHilite&quot;&gt;the&lt;/span&gt; resulting composite. &lt;span class=&quot;hitHilite&quot;&gt;The&lt;/span&gt; 2D MoO3-x layers with a large amount &lt;span class=&quot;hitHilite&quot;&gt;of&lt;/span&gt; Mo5+ oxidation states enables facile charge carrier generation due to plasmonic effect, whereas MoS2 provides active sites for catalysis. &lt;span class=&quot;hitHilite&quot;&gt;The&lt;/span&gt; solar H-2 generation was demonstrated &lt;span class=&quot;hitHilite&quot;&gt;in&lt;/span&gt; &lt;span class=&quot;hitHilite&quot;&gt;the&lt;/span&gt; visible and near-infrared region &lt;span class=&quot;hitHilite&quot;&gt;by&lt;/span&gt; combining both &lt;span class=&quot;hitHilite&quot;&gt;the&lt;/span&gt; plasmonic and catalytic effects &lt;span class=&quot;hitHilite&quot;&gt;in&lt;/span&gt; one composite. These results demonstrate &lt;span class=&quot;hitHilite&quot;&gt;the&lt;/span&gt; important role &lt;span class=&quot;hitHilite&quot;&gt;of&lt;/span&gt; RGO to provide energy-level alignment, charge carrier diffusion, and help to generate plasmonic effect &lt;span class=&quot;hitHilite&quot;&gt;in&lt;/span&gt; &lt;span class=&quot;hitHilite&quot;&gt;the&lt;/span&gt; composite.&lt;/p&gt;
