Summary: The distribution of acid sites in bifunctional catalysts and increasing the Brønsted acid sites have a positive impact on catalytic performance in FCC gasoline hydrotreatment, leading to improved hydrodesulfurization selectivity. However, an excess of strong acid sites can lead to a decrease in HDS efficiency.

Summary: A phosphorous modification method was reported to improve the HDS activity and selectivity of CoMo/δ-Al2O3 catalyst simultaneously. The enhanced HDS performance was attributed to weakened metal-support interaction, resulting in the formation of a large amount of active (Co)MoS2 phase with higher stacking and Co promotion degree. The improved Co promotion degree promotes the HDS activity, while increased stacking decreases the olefin hydrogenation activity. When applied to a real FCC naphtha, the sulfur content could be reduced to 5.4 ppm with only a total research octane number loss of 0.7 units.

Summary: The CoMoS2/Al2O3 catalysts prepared by adding citric acid showed improved activity in the hydrodesulfurization of fluid catalytic cracking decant oils. The addition of citric acid confirmed the formation of the Co-Mo-S phase, contributing to better performance in the HDS process. By classifying sulfur compounds in FCC-DO into three groups based on reactivity, the study provides insights into the mechanism of HDS.

Summary: We have developed a new strategy for controllable CF2 insertions into C-H bonds of aldehydes under transition-metal-free conditions. The success of this strategy relies on the formation of well-defined intermediates using the difluorocarbene reagent TMSCF2Br. These intermediates can react with various electrophiles, leading to the synthesis of diverse ketones containing CF2 and CF2CF2 units.

Summary: The acid-base pairing and fabrication method were employed to construct acid-base bifunctional heterogeneous catalysts. The boronic acid-amine bifunctional PANFs were prepared by introducing boronic acid groups into primary amine-functionalized polyacrylonitrile fibers via amide bond formation. The performance of the fiber catalysts PAN(EA-BA1)F and PAN(EA-BA2)F in the Henry reactions showed great correlation with the change of boronic acid, with PAN(EA-BA2)F exhibiting higher substrate selectivity.

Summary: Opposing evidence exists for the source of the hydrogen ions (H+) during ketoacidosis. Organic and computational chemistry were used to investigate the chemical reactions of ketogenesis and ketolysis and identify the sources of H+. Results showed that H+ release during ketogenesis is mainly caused by hydrolysis, while H+ release during ketolysis is predominantly caused by covalent modification. The net H+ release during ketosis depends on the proportionality of the final ketone body products.

Summary: In addition to the kidneys and lungs, the liver also plays a crucial role in regulating Acid-Base Equilibrium (ABE). Patients with liver cirrhosis may experience various acid-base imbalances, including Respiratory Alkalosis (RAlk) and other pathophysiological mechanisms such as metabolic alkalosis, hyponatremic metabolic acidosis, hyperchloremic metabolic acidosis, lactic acidosis, and metabolic alkalosis due to urea metabolism. Traditional ABE reading models fail to identify and assess these underlying disorders, leading to the development of new physicochemical mathematical models.

Summary: Oriented torrefaction mediated by acid-base balance is an efficient method for selectively converting biomass into levoglucosan. The anions of exogenous acids play a crucial role in achieving oriented torrefaction. The optimal loading amount of acid is determined by the inherent alkaline metals content of biomass divided by its cellulose content.

Summary: Understanding the origin and mechanism of methane formation from CO2 is crucial as it is linked to the origin of life on Earth. Experimental proof of methane formation on natural chromitite rock without pretreatment in the presence of CO2 and H-2 under expected atmospheric conditions shows the potential for in situ catalytic CO2 hydrogenation in rocks, suggesting a realistic alternative for CO2 mitigation and a possible pathway for the formation of organic molecules and amino acids in Nature. The presence of catalytic sites on natural rocks and their role in activating stable molecules like CO2 highlight the important role of catalysis in the formation of the first block of life on Earth.

Summary: Valorization of palm oil to produce azelaic acid, an important component for skin cancer treatment, was achieved through oxidative cleavage of unsaturated fatty acids using Ru-carbon catalysts. Triglycerides from palm oil were converted to fatty acid methyl esters, which were then reacted in a catalytic system consisting of H2O/MeCN/AcOEt with NaIO4 and N-methylmorpholine N-oxide. The Ru-carbon catalysts displayed >99% conversion and achieved a yield of around 85% for azelaic acid in 5 hours at room temperature. Furthermore, these catalysts showed good recyclability for five cycles, making them a promising option for the production of high-value-added products from cheap feedstocks like palm oil.

Summary: When the precatalyst (2,2'-Hbpy)(3)[PW12O40] reacts with H2O2 under catalytic conditions, it forms two oxidized species, an inactive byproduct (2,2'-bpyHO)(3)[PW12O40] and an activator [WO-(O-2)(2)(2,2'-bpy)]. The activator then activates H2O2 to form the active species for catalyzing the epoxidation reaction. H2O2 also serves as a conservative agent, essential for preventing irreversible deactivation of the catalyst.

Summary: Macroporous oxidized carbon black (CBO) was functionalized with 4,4'-diamino-2,2'-bipyridine (NH2-bpy) and polydopamine (PDA) to form Ru complexes for the catalytic valorization of oleic acid. The reaction produced azelaic and pelargonic acids, which are highly demanded in pharmacology. Among the three catalysts tested, the PDA-based catalyst showed the most promising results, achieving complete conversion of oleic acid with yields of pelargonic and azelaic acids around 95%. The PDA catalyst remained active even after five runs due to the re-adsorption of Ru species by catechol groups of PDA.

Summary: The non-covalent functionalization method of graphene nanoplatelets using pyrene-tagged Ru, Ni and Fe pre-cursors enables the preparation of bimetallic catalysts with different metal ratio and composition, such as Ni-Ru, Fe-Ru and Ni-Fe. Four metallic precursors (Ni (0), Ni (II), Fe and Ru) were synthesized, and 16 catalysts were prepared and characterized. The catalysts were tested in the hydrogenation reaction of glucose into sorbitol. The ruthenium-supported catalyst showed good conversion and selectivity, while the non-noble metallic catalysts Ni and Fe exhibited low performance. However, the combination of these two metals resulted in improved performance.

The nature of the support was found to have a significant influence on the catalyst's activity and selectivity, with the crystalline structure of ZrO2 having the greatest impact. Pure ZrO2 showed the highest methanol selectivity and CO2 conversion at high Zr:Ce ratios. In equimolar and Ce-rich conditions, basic sites and oxygen vacancies were found to be the key parameters affecting methanol production.

This study developed Zn-BTC MOF and its composites with CaIn2S4, achieving highly efficient and robust photocatalytic CO2 reduction to CH3OH under ambient conditions, using H2O2 as the hydrogen source. Among the composites, ZMCIS4 demonstrated excellent performance with a CH3OH evolution of 49100 μmol/g.cat and a quantum efficiency of approximately 78.41%. The enhanced performance was attributed to the production of nascent hydrogen atoms (H center dot) through the photo-splitting of H2O2 on the ZMCIS surface.

Summary: In this study, several silica-alumina catalysts modified with Ag were examined for the dehydration of 1,3-butanediol to 1,3-butadiene. Among them, an amorphous silica-alumina catalyst (SAL-3) modified with Ag showed the highest improvement in catalytic activity and stability when operated in H2 flow. The generation of reversible acid sites was found to be the reason behind the enhanced activity and stability of this Ag/SAL-3 catalyst. The effects of various parameters on the catalytic activity of Ag/SAL-3, such as reaction temperature, contact time, Ag content, and carrier gas, were investigated.
