Porous carbon materials are widely
used in adsorption, supercapacitors,
catalytic reactions, electrochemistry, and so on. However, the need
to develop porous carbon materials with easy template removal and
controllable pore size is urgent. This study provides an efficient
strategy for the preparation of boron-doped phenolic porous carbon
through in situ pyrolysis to form a template. Phenylboronic acid is
used to cross-link novolac resin. The optimization of the pyrolysis
conditions reveals that boron oxide (B2O3) is
formed at 400 °C. The porous carbon material with a high specific
surface area is obtained utilizing the hydrolysis characteristics
of B2O3. After loading titanate, 5-hydroxymethylfurfural
with a high yield (92%) is achieved at 20 °C in ethanol. The
catalytic activity showed no significant decrease after utilization
six times. The method is simple and easy to implement, providing an
efficient catalyst for the conversion of biomass materials into biofuels.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
