“…The bimetallic synergy and charge transfer effects are the important factors to promote excellent catalytic performance, and the initial furfural concentration and the aqueous system's pH required precise control to minimize polymerization and achieve high selectivity to CPO. An efficient and economical multifunctional porous Co-400 catalyst was prepared for the furfural rearrangement to cyclopentanol [22]. The highly dispersed Co 0 species and amorphous porous Co 3 O 4 species were key factors influencing high activity and chemoselectivity to the catalysts, which were precisely controlled at lower temperature.…”

The conversion of furfural to cyclopentanone over Ru-Co bimetallic catalysts was studied under a hydrogen atmosphere. It was found that furfural in water solution converted to cyclopentanone with high selectivity under 3.0 MPa and 433 K. Cyclopentanol and furfuryl alcohol were detected as by-products. Addition of cerium oxide greatly improved the catalytic performance. In the presence of 6%Ru-6%Co-6%CeO 2 /MSEP catalyst, 100% furfural conversion and 71.35% selectivity to cyclopentanone were obtained successfully. The catalysts were characterized by BET, FT-IR, XRD, SEM, TEM, TG and Hydrogen chemisorption. Additionally, the catalyst successfully operated in 5 wt% furfural solution and displayed high stability.

Liquid-phase synthesis is suitable for controlling the morphological and structural properties of functional inorganic materials and such control is important because they strongly affect the functionality of the product. Cobalt-based materials is one group of materials that requires control of powder morphology and structure. Cobalt is an important metal element used in various industrial fields such as secondary batteries, superalloys, permanent magnets, hard metals, and catalysts. The ever-growing demand of cobalt highlights that there is an urgent necessity to develop high quality material synthesis methods and to secure cobalt resources for countries that rely on import like Japan. Especially, technologies to recycle cobalt in a form reusable for secondary batteries and catalysts are desired because further increase in demand is anticipated. Meanwhile, spherical porous tricobalt tetroxide secondary particles obtained by calcination of spherical cobalt carbonate precursors have been reported to be promising materials for battery applications. Moreover, porous metal cobalt obtained by hydrogen reduction of tricobalt tetroxide is known to be effective for catalyst applications. However, conventional methods to synthesize spherical cobalt carbonate requires addition of additives in the reaction mixtures or otherwise requires hydrothermal treatment in pressure vessels. These are unfavorable to develop a practical and sustainable process for cobalt-based material production and recycling. In this study, a facile room temperature synthesis method to prepare spherical cobalt carbonate precursors from solutions of cobalt chloride and ammonium hydrogen carbonate that does not require any additives or hydrothermal treatment is developed by optimizing the carbonate solution concentration, carbonate/cobalt salt molar ratio, and stirring time during reaction. Furthermore, we succeeded in obtaining porous tricobalt tetroxide and porous metal cobalt that carry on the exterior spherical morphology of the original cobalt carbonate precursor by calcination and hydrogen reduction. The developed process shall contribute to realize high quality cobalt-based material production and recycling.
