“…However, no reproducibility was observed during the repetitive adsorption-desorption cycles leading subsequently to a decrease in CRC value due to the presence of chemical processes between the metals-NPs and surface of mesoporous silica. The same remarks were observed during the dispersion of conductive polymer polyanilyne on the surface of the SBA-15 [11].…”

“…The Figure 1 shows the infrared spectra of SBA-15 and its modified counterparts. All materials with or without modification have several characteristic absorption bands corresponding to the mesoporous silica materials [11,25]. A broad symmetrical absorption band at 3400 cm -1 is attributed to isolated silanol groups, this band is present in all samples, and it increases during the modification of the surface by the amine-copper complexes.…”

“…Among the materials suitable for adsorption of CO 2 , there are mesoporous silicas (such as SBA-15, MCM-48 and MCM-41) which have interesting physico-chemical properties [5,11,[22][23][24][25][26][27][28]. They are useful for a large number of applications mainly due to their high surface areas and large pore sizes.…”

“…The mesoporous silica SBA-15 was prepared hydrothermally using TEOS as a silica source, P123 as a structuring agent. The preparation method was well described in our previously published work [5,11,25,27]. The calcined mesoporous silica SBA-15 has been functionalized by different aminosilanes according to the method described in the literature [5,27] According to the literature, the functionalized materials were treated in a 100 mL of solution containing Cu(NO 3 ) 2 (1M) [5].…”

The mesoporous silica SBA-15 functionalized with various amines was prepared and then doped with copper (Cu ++). The modified materials were tested for the retention of CO 2 at room temperature using temperature-programmed desorption (CO 2-TPD). Several parameters affecting the CO 2 retention capacity (CRC) were investigated such as effect of the nature of amine groups, repetitive adsorption-desorption cycles and dispersion of copper. CO 2-TPD and H 2 O-TPD were employed in order to correlate the hydrophilic character with the CO 2 retention capacity. The obtained results showed that amines-functionalized mesoporous materials containing their own moisture have good results towards the retention of CO 2. Especially the triamine-functionalized SBA-15 has the greatest CRC value which results in the increase of the number of adsorption sites. The reuse of these solids in three adsorption/desorption cycles showed higher stability with a slight decrease in CRC. The dispersion of copper showed a progressive decrease in the CRC value. The correlation between the Cu% and the CRC shows that the value of the CRC decreases with increasing Cu% due to complexation of the adsorption sites (amines) by acid sites (copper).

The increasing impact of industrialization on climate change, primarily due to the emission of greenhouse gases such as carbon dioxide (CO2), underscores the urgent need for effective strategies for CO2 fixation and utilization. Electrochemical CO2 reduction holds promise in this regard, owing to its scalability, energy efficiency, selectivity, and operability under ambient conditions. However, the activation of CO2 requires suitable electrocatalysts to lower energy barriers. Various electrocatalysts, including metal‐based systems and conducting polymers like polyaniline (PANi), have been identified to effectively lower this barrier and enhance CO2 reduction efficiency via synergistic mechanisms. PANi is particularly notable for its versatile interaction with CO2, cost‐effectiveness, stability, and tunable properties, making it an excellent catalyst option for CO2 reduction reactions (CO2RR). Recent advancements in research focus on enhancing PANi conductivity and facilitating electron transfer through metal and metal oxide doping. Leveraging PANi's π–π electron stabilization ensures high conductivity and stability, rendering it suitable for real‐time applications. Strategic dopant selection and optimization of Lewis acid‐base interactions are crucial for selective CO2‐to‐hydrocarbon conversion. Tailored electrode modifications, especially metal/metal oxide‐loaded PANi electrodes, outperform conventional approaches, underscoring the importance of catalyst design in advancing CO2 electroreduction technologies. This review provides a comprehensive analysis of the systematic methodology involved in preparing PANi‐modified electrodes and explores the enhancements achieved through the incorporation of metals and metal oxides onto PANi‐modified electrodes. It highlights the superior efficiency and selectivity of CO2RR facilitated by these modified electrodes through profound synergistic approach compared to conventional metal electrodes such as platinum.
