The heterogeneous oxidation of limonene to high value-added chemicals has been recently considered as a promising way, but still remains a big challenge. Here, we construct a highly active MnCo<sub>2</sub>O<sub>4</sub> catalyst with an intriguing hollow microflower-like morphology assembled by uniform porous sheets (HMMF). When employed in the oxidation of limonene to 1,2-limonene oxide (LO), the HMMF catalyst achieves a LO yield of 64.0 % with the limonene conversion of 82.8 % and selectivity of 77.3 % to LO under mild reaction conditions, far outperforming the monometallic Co<sub>3</sub>O<sub>4</sub> catalyst. The high performance can be attributed to the synergistic benefits of bimetallic spinel structure and the unique morphology. Experimental results and theoretical research unveil that the substitution of Mn into Co<sub>3</sub>O<sub>4</sub> to form the well-defined MnCo<sub>2</sub>O<sub>4</sub> spinel promotes the establishment of highly active asymmetric Mn−O−Co centers. The reconfigured electronic structure contributes to the generation of oxygen vacancy (OV) and redox couples, facilitating the production of active oxygen species and thus boosting the oxidation kinetics. The mesoporous structure with large surface area can enhance the contact of reactive molecules with the active sites and promote the transportation of reactants and products within the channels.

Traditionally, sugar alcohols are produced industrially in batch mode using finely dispersed Raney-type nickel catalysts. In this study, novel solid foam Raney-type Ni catalysts (activated metal foam catalysts) were used for the hydrogenation of xylose to xylitol in both batch and continuous operation. Two types of catalysts were investigated: Raney-type Ni foam (Metalyst® MC 911 by Evonik Operations GmbH, Ev-F-Ni) and Raney-type Ni foam promoted with molybdenum (Metalyst® MC 981 by Evonik Operations GmbH, Ev-F-NiMo). Catalyst deactivation was primarily attributed to the accumulation of strongly adsorbed organic species on the active sites and to Ni and Al leaching, which reduced the availability of catalytically active sites. Ev-F-NiMo demonstrated a superior stability and activity compared to Ev-F-Ni, attributed to electronic interactions between Mo and Ni, which stabilize Ni in a lower oxidation state and reduce metal leaching under reaction conditions. In continuous operation, the catalysts exhibited reduced deactivation, likely due to enhanced desorption of poisons under the continuous flow of fresh feed. Although the exposure to xylonic acid, a potential poison forming on the catalyst surface, temporarily reduced the xylitol yield in continuous mode, the Ev-F-NiMo catalyst demonstrated good resilience, recovering its activity after the removal of the poisoning species.
