Summary: A series of LaNixB1-xO3 (B = Co, Cu) perovskite catalysts were prepared and investigated for toluene degradation. The results showed that Co-doping in LaNiO3 could significantly improve its toluene degradation, while Cu substitution for Ni could not effectively enhance its activity. The LaNi0.75Co0.25O3 catalyst exhibited the best activity, with relatively short time and low temperature for toluene degradation.

Summary: Double perovskite type catalysts with the formula of La2CoxFe2-xO5+d (x = 1.5, 1 and 0.5) were synthesized via a modified sol-gel method, and showed improved anti-coking and sulfur-resisting performance for steam reforming of n-hexadecane. Characterizations revealed that the special structure of double perovskite minimized coke formation and improved sulfur resisting, due to the generation of oxygen vacancies. The molar ratio of Co to Fe also had an effect on catalyst activity, and the catalyst LCF-2 (for x = 1) with a porous structure exhibited the best catalytic activity and stability.

Summary: This article discusses the use of sol-gel processes in various applications such as dry methane reforming, hydrogenation, hydrolysis, oxidation, photocatalysis, and polymerization. The most commonly used route is base-catalyzed sol-gel, which results in spherical and compact encapsulated catalysts. New methods using mild conditions for oxidation via enzymes and yeast cells are also reported. Nonhydrolytic routes are still relevant for the encapsulation of metallocenes. Silica encapsulation enables a broad range of applications for supported catalysts.

Summary: In this study, chromium and boron were introduced into the hierarchical structure of ZSM-5 to enhance the catalysts' performance in the methanol-to-propylene process. The crystal structure and orientation of the synthesized zeolites were analyzed, revealing that the introduction of chromium and boron resulted in changes in the crystallinity and symmetry of the zeolites. The impregnated chromium-ZSM-5 catalyst showed superior performance in the production of light olefins, while the introduction of boron further improved the propylene selectivity and ratio.

Summary: In this study, we compared the beneficial role of Cu/perovskite and CuyPdx/perovskite interfaces in NO + CO reaction using pure and Pd-doped LaCuxMn1-xO3 perovskite catalysts. We found that the oxygen-deficient perovskite interface provided efficient NO activation sites in contact with surface-bound monometallic Cu and bimetallic CuPd nanoparticles, leading to enhanced activity and N-2 selectivity. Our findings suggest that intelligent Cu/perovskite interfacial design is a prerequisite for replacing noble metals with equally potent metal-mixed-oxide interfaces.

Summary: This study investigates the effect of cerium and tungsten addition on the deNO(x) activity of V2O5/TiO2 catalysts in the NH3-SCR reaction. The addition of CeO2 and WO3 improves the operation temperature range and N-2 selectivity of the catalysts under dry and wet conditions. The thermal deactivation resistance of the catalysts is enhanced with increasing amount of WO3. Water decreases the overall catalytic activity at low temperatures but prevents the formation of N2O at high temperatures. CeO2 reduces the reducibility of the catalysts, while W increases the H-2 uptake.

Summary: In this study, composite materials with different compositions of LaCoO3-BaCoO3 were synthesized to determine the effect of Ba addition on LaCoO3 perovskite structures as efficient oxygen evolution reaction (OER) catalysts. The results showed that Ba did not significantly incorporate into the LaCoO3 structure, but formed BaCoO3 and BaCO3 side phases. It was also found that the addition of Ba increased the surface oxygen contribution and the number of oxygen species near surface oxygen vacancies. The electrochemical activity measurements revealed that BaCoO3 had the highest activity, with a low overpotential of 266 mV at 10 mA cm2 and excellent stability. These findings suggest that Ba-based perovskite materials have the potential to improve the electrochemical performance of current OER catalysts.

Summary: Perovskite materials SrFexCo1-xO3-delta (SCF-x, x = 0.2, 0.5, 0.8) were synthesized by sol-gel combustion and studied as electrode materials for supercapacitors. The synthesized samples were characterized using X-ray Diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR), Raman spectroscopy, Scanning Electron Microscope (SEM), and Energy Dispersive X-ray Spectroscopy (EDS). Substitution in the perovskite structure affected the oxygen vacancy concentration and changed the electrochemical properties. SCF-0.8 exhibited the highest specific capacitance (433 F center dot g(-1)) at 2 A center dot g(-1) current density due to its morphology, crystal structure, and higher oxygen vacancy concentration. The electrochemical stability of SCF-0.8 was tested and it retained around 60% of its initial specific capacitance after 2500 charge-discharge cycles.
