Summary: Nanocrystalline Ni/CeO2 catalysts prepared by urea-nitrate combustion synthesis showed good catalytic performance in glycerol steam reforming. Characterization of the catalysts revealed that NiO mainly existed in the X-ray amorphous state and remained in the Ni-0 particles after reduction. Increasing the Ni content inhibited the agglomeration of CeO2 crystallites and increased the defectiveness of CeO2. The sample with 6.8 wt% Ni exhibited the best catalytic performance.

Summary: A series of 5%Ni/Ce1-xTixO2 catalysts were prepared using nickel impregnation of mixed Ce-Ti oxides obtained via synthesis in supercritical isopropanol. The addition of Ti into the cubic fluorite phase structure increased the total reducibility of the catalysts and improved the interaction of supported Ni with the oxide support. The incorporation of Ti also prevented the detachment and sintering of Ni particles during dry reforming of methane.

Summary: This study demonstrates a facile aerosol-based method to prepare hybrid nanostructures for catalyzing steam-promoted CO2 reforming with methane. The resulting NiPdOx-CeO2 nanoparticles deposited on SiO2 nanoparticle clusters exhibit superior catalytic performance at low temperatures, with high turnover frequency, tunable H2/CO ratio, and long-term operation stability. Incorporating SiO2 nanoparticle clusters as support material helps to enhance the dispersion of active metals and suppress metal sintering.

Summary: Supported IrOx nanocatalysts are more active but less stable for OER compared to unsupported micrometer-sized catalysts, while Ta-doped tin oxides used as supports for IrOx nanoparticles show higher stability. Thermal annealing significantly reduces Ir atom dissolution rate for both micro- and nano-IrOx particles, leading to improved stability.

Summary: Electrochemical advanced oxidation processes (EAOPs), particularly the heterogeneous electro-Fenton (EF) process, with in-situ formation of hydrogen peroxide (H2O2), have shown great potential for the effective and environmentally friendly treatment of refractory organic pollutants. This article discusses the surface catalytic mechanisms for H2O2 activation in the heterogeneous EF process and summarizes the required features for H2O2 formation via selective oxygen reduction reaction (ORR) with carbonaceous electrodes. It also provides an overview of solid Fenton catalysts and integrated functional cathodes used in heterogeneous EF for wastewater treatment, along with a brief discussion on their catalytic activity and stability under different experimental conditions. Additionally, the application of heterogeneous EF process in the remediation of emerging contaminants is highlighted, while emphasizing the challenges and future prospects related to catalytic fall-off and multi-step/complex techniques for water purification.

Summary: This study conducted a sequential analysis using UPS and XPS on ceria nanopowders to investigate the influence of X-ray beam on the oxide's surface. It was found, for the first time, that XPS analysis had a photoreductive effect on ceria after an oxidative pretreatment, leading to an overestimation of the Ce3+/Ce4+ ratio obtained by XPS. This spectroscopy methodology, particularly UPS, emerged as a leading technique for powder analysis with minimal impact on the authentic chemical state, facilitating the identification of the actual Ce4+ and Ce3+ ratio of ceria after oxidative and reductive in situ treatments.

Summary: In this study, hydrogen trapping in small Pd nanoparticles was explored through experimental and theoretical approaches. The results showed that the smaller the Pd particle size, the larger the amount of trapped hydrogen and the stronger the binding energy experienced by hydrogen atoms. The simulations indicated that the strong hydrogen trapping sites are octahedral interstitials located at the subsurface of Pd nanoparticles.

The atomic catalyst (Fe-SAC) with Fe-N5 as the active center was constructed, effectively activating peroxymonosulfate (PMS), peroxydisulfate (PDS), and hydrogen peroxide (H2O2). The study demonstrates the degradation efficiencies of acyclovir are related to the O-O bond length in different peroxy compounds, and reveals the discriminative mechanisms for activation of O-O bond in different Fenton-like systems.
