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