Quest for pore size effect on the catalytic property of defect-engineered MOF-808-SO4 in the addition reaction of isobutylene with ethylene glycol

Tuning the Properties of MOF‐808 via Defect Engineering and Metal Nanoparticle Encapsulation

“…The pristine material MP shows the highest BET area. The values obtained in this study are consistent with ones published in the literature which vary between 1205 m 2 g −1 and 2060 m 2 g −1 for pristine MOF‐808 samples [33, 34, 46, 48, 49] …”

“…It may be related to the roughness of the crystal surface, the presence of holes (Figure 1 d and 1d’) and to the particle sizes that are all responsible for an increase in the external surface area. Such behaviour was reported in defective and impregnated MOF 808 but also in pristine MOF 808 [45–48] . The surface area (BET method) and the pore volume at p / p 0 =0.7 were calculated for each sample and the values are tabulated in Table 2.…”

A continuous flow chemistry approach for the ultrafast and low-cost synthesis of MOF-808

“…An initial weight loss of ∼3% below 140 °C could be attributed to the loss of physisorbed water, while an additional ∼18% weight loss was observed due to loss of coordinated water and formate ions on the SBU up to 300 °C. 65 A significant weight loss of ∼33% was observed at ∼500 °C that resulted from decomposition of the organic linkers in the framework as shown previously. 66 Owing to the amorphous nature of 1 min sample, it showed a steady weight loss without any distinct features common to those in crystalline samples.…”

“…The BET surface area for the batch synthesized sample was ∼1900 m 2 g −1 similar to that reported in previous studies. 10,14,65 The pore size distribution (PSD) was calculated using non-local density functional theory (NLDFT) based on the carbon slit-pore model as shown in Fig. 3b.…”

Engineering Nanoscale Metal‐Organic Frameworks for Heterogeneous Catalysis

“…[ 98–103 ] The size, type, exposed functional groups and flexibility of the pores all have the significant effect on the catalytic activity. [ 104–112 ] As for the reaction substrates of large size or multicomponent, sufficient pore size ensures that the reactants fully contact with the catalytic center to be transformed. [ 113–120 ] Upon the catalytic conversion into specific products, the size of the pores needs to match the corresponding product range, thereby improving the selectivity.…”
