    <description descriptionType="Abstract">&lt;p&gt;We report the influence of structural features on the properties of porous carbonaceous materials obtained using soft-templating coupled with hydrothermal carbonisation. Our results demonstrate that using &lt;em&gt;d-&lt;/em&gt;glucose with Pluronic P123 results in a more homogeneous particle size distribution of carbon spheres compared with &lt;em&gt;d-&lt;/em&gt;fructose. The textural properties of the carbon materials, both surface area and pore volume, have improved when the carbonisation temperature was increased from 550 &amp;deg;C to 900 &amp;deg;C, while the amount of C=C bonds was also increased. Physical activation with CO&lt;sub&gt;2&lt;/sub&gt; was found to open the pores and thereby improve textural properties, including total pore volume, micropore volume, and surface area. Concomitantly, the CO&lt;sub&gt;2&lt;/sub&gt; and H&lt;sub&gt;2&lt;/sub&gt;S uptake also underwent significant enhancement, achieving a maximum CO&lt;sub&gt;2 &lt;/sub&gt;adsorption capacity of 8.37 mmol/g at 0 &amp;deg;C and 1 bar, and &lt;em&gt;ca.&lt;/em&gt; 6 mmol/g at room temperature and 1 bar. The same samples showed about 25.7 mmol/g adsorption capacity for H&lt;sub&gt;2&lt;/sub&gt;S at room temperature and atmospheric pressure, with approximately 32% process efficiency.&lt;/p&gt;</description>
