Summary: The study synthesized zeolite TS-1 co-loaded with silver and titanium dioxide nanoparticles using ion-exchange and in-situ photodeposition methods, resulting in a sample with high surface area, rich defects, and highly dispersed silver nanoparticles. The sample exhibited high CO2 adsorption capacity and improved separation efficiency of photogenerated electron-hole pairs, leading to selective CO and CH4 production with suppressed H2 evolution during photocatalytic CO2 conversion. The super photocatalytic activity was attributed to the synergistic effect among the dispersed silver nanoparticles, support zeolite TS-1, and titanium dioxide with highly exposed {101} planes.

Summary: A Z-scheme heterojunction with all-solid-state structures was constructed, in which carbon dots acted as electron transferring mediators. The modified photocatalysts showed significantly higher activities, with ammonia production rates reaching above 232 lmol center dot gcal-1 center dot h-1 under light irradiation. The improved catalytic properties were attributed to the increased number of photoinduced oxygen vacancies, excellent visible-light adsorption abilities, and efficient photogenerated electron-hole separation efficiencies for the carbon dots bridged heterostructures. This study provides reasonable guidance for applications in photocatalytic ammonia synthesis and a promising construction strategy for efficient Z-scheme photocatalysts.

Summary: Photocatalysis technology is a promising strategy to convert CO2 into fuels and mitigate the greenhouse effect and energy crisis. In this study, the Z-scheme Ag/UiO-66@g-C3N4 composites showed improved CO2 photoreduction activity due to their increased specific surface area, strong redox capacity, rapid separation of photoinduced h+/e- pairs, and fast transfer of e-. The CH3OH and CO evolution rates of the composites were 3.09 and 2.40 times higher than those of g-C3N4, respectively. The Quantum yield (QY) of CO and CH3OH for the composites were 0.0217% and 0.0986%. The Ag NPs acted as e- mediator, promoting charge separation, transport, and CO2 reduction ability. This study not only presents a simple method to prepare ternary composites but also demonstrates their efficient photocatalytic CO2 conversion to methanol and CO.

Summary: In this study, the concentration of 25 elements in beer samples was determined using different analytical techniques. The results showed that these elements can originate from various sources, including raw materials and brewery equipment. Discriminant analysis based on elemental concentrations could differentiate between different types of beer, and the choice of packaging material also had an impact on some element concentrations. Risk assessment analysis indicated that moderate consumption of beer had no adverse effects, except for beer stored in aluminum cans.

Summary: A porous TiO2 layer was prepared by plasma electrolytic oxidation (PEO), followed by deposition of Pd on the TiO2 surface layer using the adsorption method. The Pd/TiO2/Ti catalyst exhibited high activity for the oxidation of CO to CO2 in air with 5% CO. The optimal Pd concentration on the catalyst surface was found to be approximately 0.14% wt., and increasing the PdCl2 concentration did not further improve the catalyst activity.

Summary: This study evaluated the service life of dental restoration materials in aggressive environments. The results showed that neat resins exhibited poor durability, while materials with lower bis-GMA content or substituted by bis-EMA showed better resistance to degradation. Choosing monomer mixtures with lower sorption values may improve hydrolytic stability. The composites experienced a significant decrease in hardness, indicating a more superficial effect of the aging protocols.

Summary: The activity of Pd/TiO2/Ti catalyst in CO oxidation was improved by adding Zn. Plasma electrolytic oxidation (PEO) was used to produce a porous layer of TiO2 on Ti wire. Pd and Zn were introduced through adsorption, and the activity was examined by CO oxidation. Model catalysts were prepared to investigate the reaction between Pd and Zn. Characterization techniques such as SEM-EDS, TOF-SIMS, ICP-MS, FTIR, and XRD were used to analyze the structures and compositions of the samples. Zn modification of the Pd/TiO2/Ti catalyst decreased the temperature of CO oxidation and improved the adsorption of oxygen.

Summary: This study presents a mechanistic investigation of methane oxy-steam reforming and LNG (OSR-LNG) processes using Fourier transform infrared (FTIR) spectroscopy for the first time. FTIR measurements were conducted in the temperature range of 200-600 degrees Celsius to propose the reaction mechanisms of oxy-steam reforming of CH4 or LNG. It was discovered that the dissociation of methane into carbon-containing molecules and/or onto the catalyst surface is a crucial step in determining the reaction rate. These findings can be applied to the design of catalytic systems for natural gas reforming.

Summary: Investigation on the course of the Boudouard reaction and methane cracking was conducted using nickel catalysts based on calcium, aluminum, and magnesium oxides. The study revealed that the optimal temperatures for these reactions were 450 and 700 degrees C, respectively, resulting in the successful formation of graphite-like carbon species. The activity of the catalytic systems was found to be directly related to the number of weakly interacted nickel particles with the catalyst support.

Summary: In this study, multi-walled carbon nanotubes (MWCNTs) were prepared by chemical vapour deposition (CVD) using acetylene as a carbon source over an iron catalyst. The feasibility of MWCNTs supported monometallic and bimetallic catalysts for hydrogen production during steam reforming of methanol (SRM) and methanol decomposition (DM) was investigated. SEM and XRD methods were used to evaluate the structural characteristics of MWCNTs. TPR and XRD methods were used to analyze the physicochemical properties of the catalysts. The promotion effect of palladium on methanol conversion rate and H2 productivity in the case of the copper catalysts was demonstrated, which was attributed to the formation of Pd-Cu alloy compound.

Summary: The effect of a new etching technique (Zircos-E) on Ceramill Zi (Amann Girrbach) zirconia was investigated. Surface preparation for bonding is difficult due to the polycrystalline structure of zirconia. Etching zirconia ceramics resulted in changes in surface structure and increased bond strength with resin cement. The use of primers positively affected the adhesion between resin cement and zirconia. The Zircos-E system and primers improved the strength of the zirconium-resin cement connection.
