Nitrogen-Doped Porous Carbon Derived from Bamboo Shoot as Solid Base Catalyst for Knoevenagel Condensation and Transesterification Reactions

Abstract

Highly porous nitrogen-doped carbons derived from bamboo shoots (BSNCs) were prepared through an in-situ synthesis method. The results showed that BSNCs had a large specific surface area, a relatively high nitrogen content and hierarchically porous structures. The catalytic properties of BSNCs were evaluated based on Knoevenagel condensation and transesterification reactions. Deprotonated BSNC-700 exhibited high efficiency for the model reactions as a solid base catalyst, and the superior sample deprotonated in tBuOK solution with a concentration of 0.1 increased the conversion rate from 16.1% to 76.0% for Knoevenagel condensation. The two reactions proceeded smoothly in the presence of deprotonated BSNC-700. The results also showed that the catalyst could be recycled for several times for Knoevenagel condensation. The results from this research will provide a guideline to develop bamboo shoot as a precursor to fabricate a superb solid base catalyst.

Controlled alcohol oxidation reactions by supported non-noble metal nanoparticles on chitin-derived N-doped carbons

“…From the literature, the occurrence of nitrogen centres in carbon materials has been often reported advantageous to achieve catalysts suitable for a range of processes, particularly base-catalysed reactions or even in tandem sequences. 28,30,31 The four materials obtained as described in Fig. 1 were fully characterized through a multi-technique approach, including XRD, N 2 -physisorption, XPS and HRTEM-mapping analyses.…”

Guanine‐Derived Porous Carbonaceous Materials: Towards C1N1

“…The majority of heterogeneous base catalysts in the literature are pre‐treated with strong bases to activate the base functionalities (to de‐bind potentially pre‐bounded acids), while simple degassing works for guanine‐derived porous condensates (see Table S2) [17,24] . The results indicate that the design of basic catalysts strongly depends on both their composition and pore morphology, balancing the effects of activation, activity, and accessibility.…”

Nitrogen Self-Doped Activated Carbons Derived from Bamboo Shoots as Adsorbent for Methylene Blue Adsorption

“…The raw material (bamboo shoot, Phyllostachys pubescens ) used in this study [47], was collected from Lishui, Zhejiang Province, China. The scale-like outer skin of bamboo shoots were removed, cut into slices and dried at 70 °C for 12.0 h in the oven.…”
