This study investigates the use of Co-based catalysts derived from different materials including CoAl-layered double hydroxide (LDH), LDH/melamine, LDH/activated carbon, and LDH/g-C3N4 in the hydrogenation of gamma-valerolactone into 1,4-pentanediol. The CoAl-LDH/g-C3N4 catalyst showed improved turnover frequency due to its higher concentrations of strong Bronsted acid, Lewis acid, and Lewis base sites.
Co-based catalysts were derived from CoAl-layered double hydroxide (LDH), LDH/melamine, LDH/activated carbon, and LDH/g-C3N4. The use of these catalysts for the hydrogenation of gamma-valerolactone into 1,4-pentanediol was investigated. The catalyst derived from CoAl-LDH/g-C3N4 contained higher concentrations of strong Bronsted acid, Lewis acid (Co delta+, delta > 2), and Lewis base (N with a lone pair of electrons) sites, resulting in improved turnover frequency.
