A resorcinol-formaldehyde resin carbon (RFC) catalyst with a well-developed, ordered, mesoporous framework was prepared using a soft template method at room temperature. The carbon was sulfonated in water using sulfanilic acid under mild atmospheric conditions. The sulfonated RFC (S-RFC) was characterized by N 2 adsorption-desorption, elemental analysis, TEM, XPS, and FT-IR. It was determined that S-RFC is an efficient solid acid catalyst for furfural production from xylose and corn stover in gvalerolactone (GVL). The effects of reaction time, reaction temperature, catalyst loading, substrate dosage and water concentration were investigated. 80% furfural yield and 100% xylose conversion were obtained from xylose at 170 C in 15 min with 0.5 g catalyst. Comparatively, 68.6% furfural yield was achieved from corn stover at 200 C in 100 min when using 0.6 g catalyst. Since there was no discernable decrease in furfural yield after multiple conversions utilizing the same catalyst, the recyclability of the catalyst is considered good.

“…The synthesis of magnetic nanoparticles has attracted renewed research interest in recent years, driven by their new applications such as advanced magnetic materials [1][2][3][4][5], ultra high-density magnetic storage media [6] and biological imaging [7]. Among these magnetic nanoparticles, iron oxides (Fe 2 O 3 and Fe 3 O 4 ) have been extensively investigated due to its excellent performance.…”

“…TEM images of Fe‐NOHPC and Fe‐N‐doped porous carbon (Fe‐NPC) are shown in Figure 1. For the Fe‐NOHPC samples pyrolyzed at 900 °C, a stripe‐like morphology is observed (Figure 1 a), which demonstrates its highly ordered hexagonal structure,12a, 14 although the edge also shows an amorphous structure that results from carbonization under the NH 3 atmosphere. TEM analysis also reveals the large‐domain regularity of Fe‐NOHPC and the thermal stability of its hexagonal structure.…”

Si‐Artemone (4a), Si‐β‐Dynascone (5a), and Si‐Herbac 6a, which are Si analogues of the commercial fragrance ingredients Artemone (1), β‐Dynascone (2), and Herbac (3), were synthesized expediently by the insertion of terminal alkynes into silacyclobutane 7a. The sensory characterization results revealed that 4a and 6a had quite similar odor qualities compared with those of 1 and 3, whereas 5a had a totally different odor character relative to that of 2. In terms of the odor threshold values, that of 4a was slightly more substantive than that of its carbon analogue 1, 6a was less potent than its carbon analogue 3, whereas that of 5a was approximately one‐sixth that of its carbon analogue 2.
