[PMID: 38234868 PMCID: PMC10792728 DOI: 10.1039/d3ra07306h] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2023] [Accepted: 12/19/2023] [Indexed: 01/19/2024] Open
Abstract
A series of Ru-Sn/γ-Al2O3 catalysts were prepared by the immersion method for tetramethylcyclobutane-1,3-dione (TMCB) hydrogenation to prepare 2,2,4,4-tetramethyl-1,3-cyclobutanediol (CBDO). The effect of the preparation method and reaction technology on TMCB hydrogenation activity was discussed. The catalysts were analyzed by means of XRD, BET, H2-TPR, XPS, scanning electron microscopy (SEM), and transmission electron microscopy (TEM), and it was found that the synthesized Ru was distributed on the surface of the carrier in the form of nanoparticles, showing a good catalytic effect. The results showed that when Ru loading was fixed at 5%, Sn was used as an auxiliary agent, and Ru/Sn = 1 : 1 as the catalyst, the reaction conditions were 120 °C, 4 MPa, and 1 h, and the catalytic hydrogenation effect of TMCB on CBDO was the best. The selectivity was as high as 73.5%, and the cis-trans ratio was 1.11. It may be the strong interaction between Ru and Sn under this ratio condition, which leads to the largest number of nano-active centers of elemental Ru. Finally, the reaction mechanism of TMCB hydrogenation to CBDO is discussed.

Abstract
Chlorinated volatile organic compounds (CVOCs) are still a part of the current atmospheric environmental problems that cannot be ignored, but unlike conventional VOCs, the presence of Cl causes various catalyst deactivations in the catalytic process. In this paper, we focus on six common CVOCs and discuss various behavioral mechanisms of the whole catalytic process from six aspects: catalyst selection, factors affecting the catalytic effect, changes in catalytic behavior in the presence of different gases, catalyst poisoning deactivation behavior, degradation products and degradation mechanisms to provide guidance for further development of low-temperature and efficient CVOCs catalysts.

Abstract
Abstract
Volatile organic compounds (VOCs) are mainly derived from human activities, but they are harmful to the environment and our health. Catalytic oxidation is the most economical and efficient method to convert VOCs into harmless substances of water and carbon dioxide at relatively low temperatures among the existing techniques. Supporting noble metal and/or transition metal oxide catalysts on the porous materials and direct preparation of mesoporous catalysts are two efficient ways to obtain effective catalysts for the catalytic oxidation of VOCs. This review focuses on the preparation methods for noble-metal-based and transition-metal-oxide-based mesoporous catalysts, the reaction mechanisms of the catalytic oxidations of VOCs over them, the catalyst deactivation/regeneration, and the applications of such catalysts for VOCs removal. It is expected to provide guidance for the design, preparation and application of effective mesoporous catalysts with superior activity, high stability and low cost for the VOCs removal at lower temperatures.

A comparative study of the dichloromethane catalytic combustion over ruthenium-based catalysts: Unveiling the roles of acid types in dissociative adsorption and by-products formation. J Colloid Interface Sci 2021; 605:537-546. [PMID: 34340038 DOI: 10.1016/j.jcis.2021.07.095] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2021] [Revised: 07/14/2021] [Accepted: 07/18/2021] [Indexed: 01/19/2023]
Abstract
Herein, a comparative investigation of the Ru-based catalysts with different kinds of supports (TiO2, Al2O3, HZSM-5 SiO2/Al2O3 = 27 and 130, respectively) for catalytic combustion of dichloromethane (DCM) has been performed. The characterization results showed that the C-Cl bond of DCM was cleaved on both the Brønsted and Lewis acid sites of the catalysts. However, the Lewis acid sites were more active than the Brønsted acid sites. The relatively strong Lewis acidity of Ru/TiO2 improved the dissociative adsorption of DCM, accounting for its superior activity. The yield of toxic by-products was strongly associated with the acid types of the catalysts. The Cl species deposited on TiO2 and Al2O3 supports interacted strongly with the Lewis acid sites, thereby promoting the electrophilic chlorination reactions and yielding more polychlorinated by-products, especially highly toxic dibenzo-p-dioxins and dibenzofurans (PCDD/Fs). However, the Cl deposits on Ru/HZSM-5 (SiO2/Al2O3 = 27) with abundant Brønsted acid sites, mainly existed as hydrogen-bonded Cl species, with good mobility and less propensity for chlorinating carbonaceous matter. Moreover, Ru/HZSM-5 (SiO2/Al2O3 = 130) yielded the highest polychlorinated by-products and PCDD/Fs because of its poor redox ability and high surface area. Overall, this study provides valuable insights into the CVOCs catalytic combustion catalysts development.
