Characterization of porous microspheres prepared via γ-ray irradiation

Methyl methacrylate-modified polystyrene microspheres: an effective strategy to enhance the fluorescence of Eu-complexes

“…35–37 Existing experimental data show that when monomer MMA and water were stabilized within the particles, an inner phase separation phenomenon occurred, thus resulting in the formation of a porous structure. 38,39 And the results further proved the existence of the porous structure as shown in Fig. S3(b) (ESI†).…”

Core–Shell Design of Metastable Phase Catalyst Enables Highly‐Performance Selective Hydrogenation

“…Figure 3f clearly reveals the chemical vibrations of C=C (≈1632 cm −1 ), benzene skeleton (≈1492 cm −1 ), and aromatic C−H (≈775 and ≈695 cm −1 ) of pure styrene for reference. [ 56 ] For hcp Ni and fcc Ni catalysts, the strong absorption peaks at C=C, benzene skeleton, and aromatic C−H can be seen, indicating the strong adsorption capacity of styrene on these two catalysts. It can be observed that fcc Ag@fcc Ni also has an obvious absorption peak at C=C, benzene skeleton, and aromatic C−H, which means that the catalyst has a certain adsorption capacity for styrene.…”
