“…As presented in Table S2, the percentage composition of carbon (Atomic %) in the bare silica, MIP/SiO 2, and NIP/SiO 2 were 0.95%, 31.49%, and 11.83%, separately. On bare silica, the C peak is perhaps caused by the contamination of the testing process [42]. The carbon contents of the materials by XPS were different from those by Vario EL III elemental analyzer, the reason probably originated from their different test principle.…”

The molecular imprinting technique has aroused great interest in preparing novel stationary phases, and the resulting materials named molecularly imprinted polymers coated silica packing materials exhibit good performance in separating diverse analytes based on their good characteristics (including high selectivity, simple synthesis, and good chemical stability). To date, monotemplate is commonly used in synthesizing molecularly imprinted polymersbased stationary phases. The resulting materials always own the disadvantages of low column efficiency and restricted analytes, and the price of ginsenosides with high purity was very high. In this study, to overcome the weaknesses of molecularly imprinted polymers-based stationary phases mentioned above, the multi-templates (total saponins of folium ginseng) strategy was used to prepare ginsenosides imprinted polymer-based stationary phase. The resulting ginsenosides imprinted polymer-coated silica stationary phase has a good spherical shape and suitable pore structures. Additionally, the total saponins of folium ginseng were cheaper than other kinds of ginsenosides. Moreover, the ginsenosides imprinted polymer-coated silica stationary phase-packed column performed well in the separation of ginsenosides, nucleosides, and sulfonamides. The ginsenosides imprinted polymer-coated silica stationary phase possesses good reproducibility, repeatability, and stability for seven days. Therefore, a multitemplates strategy for synthesizing the ginsenosides imprinted polymer-coated silica stationary phase is considered in the future.

Acetaminophen (AP) is a widely used antipyretic analgesic belonging to the class of PPCPs, which is di cult to be effectively degraded by traditional water treatment processes. However, photocatalytic technology may be an effective approach. Herein, B-doped TiO 2 photocatalytic materials were synthesized by sol-gel method, calcinated at 600℃ for 2 h, investigated by XRD, TEM, XPS and other characterization methods. The photocatalytic e ciency and factors affecting the photocatalytic activity were assessed by degradation of AP under 365 nm UV light. Compared with naked TiO 2 , 4%B-TiO 2 nanopowder had smaller grain size, higher porosity and lower bandgap energy of 3.11 eV. Scavenging experiments and ESR results showed that •OH was the principal active species. Hence, the degradation e ciency of AP was as high as 98.8% in 30 min when adopting 10 mg/L AP initial concentration and 1 g/L 4%B-TiO 2 loading, owing to e cient •OH generated by B-TiO 2 .
