New flexible funding paper on adsorption from Salman Soltani

Congratulations to Salman Masoudi Soltani, whose research paper for his UKCCSRC 2020 flexible funding project has just been published!

Salman’s paper, Influence of surface modification on selective CO2 adsorption: A technical review on mechanisms and methods, highlights some key issues and discussion point around adsorbents, and includes:

  • a critical review of surface modification methods employed to enhance CO2 adsorption
  • assessment of CO2 adsorption mechanisms in the context of surface functional groups
  • evaluation of the methods used to introduce functional groups on adsorbent surfaces
  • a critical discussion of the reagents used in surface modification of adsorbents.

However, even with the myriad materials such as zeolites, carbons, metal organic frameworks, mesoporous silicas and polymers, the challenge to identify a sorbent with optimal capacity, kinetics, selectivity, stability and ultimately, viability, still persists. By tailoring these solid materials through comprehensive campaigns of surface modification, the pitfalls of each can be mollified and the strengths enhanced. This highly specific tailoring must be well informed so as to understand the mechanisms by which the CO2 is adsorbed, the surface chemistry that has influence on this process, and what methods exist to facilitate the improvement of this.

Salman’s research endeavours to identify the surface functional groups that interact with the CO2 molecules during adsorption and the methods by which these functional groups can be introduced. It also provides a comprehensive review of the recent attempts and advancements made within the scientific community in the experimental applications of such methods to enhance CO2 capture via adsorption processes.
