Summary: Four types of Pt/C catalysts were synthesized by depositing platinum on various carbon materials, and Pt nanoparticles were found to predominantly exist on graphene, graphitic carbon nitride, and carbon nanotubes. Among these catalysts, Pt/CNTs exhibited the highest efficiency in catalyzing CO oxidation.

Summary: In this study, ruthenium-based phosphorus-doped carbon (RuOx/P-C) hybrids were synthesized using lignin and phytic acid as carbon and phosphorus sources, forming lignin-phytic acid networks via complexation and electrostatic interaction. The resulting RuOx/P-C catalysts exhibited enhanced catalytic performance for solar-assisted water splitting. For the hydrogen evolution reaction, RuOx/P-C achieved low onset potentials and small Tafel slopes in acidic and alkaline electrolytes. In the photoelectrochemical cell, RuOx/P-C/W:BiVO showed a significantly higher photocurrent compared to pristine W:BiVO, attributed to the synergistic coupling effects among active species.

Summary: In this study, copper and nickel were incorporated into yellow clay using the wet impregnation method to prepare CuNi-YC catalysts for the catalytic oxidation of Caffeine. The catalysts were characterized using various techniques, and the effects of different factors on catalytic activity were optimized using the Box-Behnken Response Surface Methodology. The results show that under the optimized conditions, the CuNi-YC catalyst exhibited high stability and efficiency for Caffeine conversion.

Summary: Pristine graphitic carbon nitride-based catalysts (g-C3N4) show limitations in practical CO oxidation applications, such as low surface area, sluggish electron transfer, inadequate gas activation, poor electrical conductivity, and weak visible-light absorption. These issues can be addressed by incorporating heteroatoms, metals/metal oxides, and single atoms into g-C3N4 nanostructures, as well as coupling g-C3N4 with other semiconductors to form heterojunction structures. Additionally, electron donation from the g-C3N4 support enhances O-2 adsorption and activation. This review aims to provide a comprehensive understanding of the rational design and challenges of g-C3N4-based catalysts for CO oxidation.

Summary: The introduction of a nitrogen-doped carbon layer onto the Pt/C surface resulted in a significant enhancement in stability and specific activity for the Pt/C@NC-0.06 sample, compared to the pristine Pt/C catalyst. This improvement provides a promising way to enhance the electrocatalytic performance of catalysts in PEMFCs.

Summary: The application of composite materials as catalysts for air purification by oxidizing CO and other toxic compounds is promising. This study investigated composites of palladium and ceria components supported on carbon nanotubes, carbon nanofibers, and Sibunit in the oxidation reactions of CO and CH4. The results showed that carbon nanomaterials stabilize the deposited components in a highly-dispersed state, forming nanoparticles, clusters, and atoms. The interblock contacts between nanoparticles have an important effect on oxygen transfer, which influences the catalytic activity. The optimal combination of dispersed species and nanoparticles in the CNTs-based catalyst makes it highly effective in both studied reactions.

Summary: Direct ethanol fuel cells have great potential as clean electrochemical power sources, but their commercialization is hindered by the high cost and low efficiency of Pt-based catalysts. Pt-Sn-Co nanocubes with a Pt-and Sn-rich shell showed improved performance for the electrochemical ethanol oxidation reaction (EOR) due to the leaching of Sn from the core and shell, leading to electrochemically-accessible Pt sites adjacent to partially-oxidized Sn sites on a Pt3Co-like core. The increased activity of the Pt-Sn-Co nanocubes was attributed to the higher production of C-1 (CO2) and C-2 (acetic acid/acetaldehyde) products during EOR as well as their ability to remove adsorbed CO from the Pt surface.

Summary: Supported metal catalysts are widely used in industrial processes, and the size of the metal particles is crucial for the catalytic performance. This study investigates CeO2-supported Pd catalysts with different Pd size regimes and reveals that single Pd atoms supported on CeO2 have the highest intrinsic activity in CO oxidation and promote the CO-PROX reaction due to a stronger H-spillover effect.

Summary: In this study, nitrogen-doped Fe/Co bimetallic electrocatalysts were prepared using adjusted metal-organic frameworks, showing excellent oxygen reduction reaction (ORR) activity and methanol crossover tolerance. The desirable performance is attributed to the uniform distribution of Co3Fe7 active sites, electron density modification, and hierarchical pore structure with large surface area.

Summary: The study demonstrates that ternary PtCoRh alloyed spiral nanowires can serve as active and robust MOR electrocatalysts in acidic media, showing high mass activity and specific activity, as well as excellent durability. The incorporation of Rh atoms stabilizes the nanowires, prevents leaching of Co atoms, and enhances electron transfer among metallic elements, leading to improved MOR activity, structural stability, and anti-CO-poisoning ability. This work provides a rational strategy for developing efficient and durable alcohol oxidation electrocatalysts.

Summary: Metal-organic frameworks (MOFs) derived nanomaterials have shown great potential as catalysts for oxidation and hydrogenation due to their uniform active sites, hierarchical porosity, composition diversity, easy functionalization, and high stability. This review summarizes recent research on MOF-derived catalysts, including their synthesis parameters, chemical composition, morphology, structure, and catalytic performance. The emphasis is on the influence of pore structure, size of active nanoparticles, and heteroatom doping on reactant conversion and product selectivity under green and mild reaction conditions.
