Summary: A series of CuO-based nanoparticle catalysts supported by different materials were prepared and used for the synthesis of glycerol carbonate. The catalytic activity was influenced by the CuO loading amount, calcination temperature, and properties of the support materials. CuO/Al2O3 exhibited the highest catalytic activity due to its surface area and number of basic sites. The catalyst showed a synergistic effect with 2-cyanopyridine, allowing for glycerol activation and CO2 promotion. The catalyst could be recycled for multiple cycles without deactivation.

Summary: The study found that Cu/ZrO2 catalyst exhibited the highest activity and apparent reaction rate in the dehydration of glycerol to hydroxyacetone process, attributed to the highly acidic support and positive roles of interfacial sites. The application of Weisz-Prater (WP) criterion confirmed the absence of intraparticle diffusion limitations, and DFT study suggested that the active sites are located at the interface of Cu particles and the acidic support.

Summary: In this study, ordered nanostructured KIT-6 silica with different numbers of sulfonic groups were synthesized. The amount of the functional group precursor used affected the structural and textural parameters of the synthesized materials. The samples modified by grafting exhibited a stable mesoporous structure, while the ones synthesized by co-condensation showed characteristics of KIT-6 materials. The developed synthesis procedures yielded potential solid acid catalysts with desirable catalytic performances.

Summary: A systematic study was conducted to determine the maximum amount of nickel incorporated into the gamma-Al2O3 structure to form NiAl2O4. The behavior of this catalyst precursor for glycerol hydrogenolysis and cyclohexane conversion was investigated. Various characterization techniques were used to study the prepared catalysts with different nickel content. The results showed that Ni could be reversibly inserted into the gamma-Al2O3 structure, and the maximum amount of Ni incorporated into NiAl2O4 was approximately 20 wt%Ni. Different forms of Ni0 particles were observed depending on the Ni content, and their nature affected the catalytic activity. The formation of gridshell structures was found to be a determining factor for the catalytic activity in liquid-phase reactions.

Summary: This review summarizes the progress in carbon-based materials for oxygen reduction reaction (ORR) catalysts and their utilization in microbial fuel cells (MFCs). Incorporating transition metals and heteroatoms into carbon can enhance the ORR activity and power generation in MFCs. Nitrogen-doped carbons have abundant active sites and superior conductivity, stability, and catalytic activity. Carbon-based catalysts and biomass-derived carbons show potential to replace expensive Pt catalysts for ORR.
