“…STEM-EDS maps reveal a localization of the S signal on the NPs (Figure E), and SERS signals from both analytes are observed (see next section). While thiols are not expected to interact in the same way with an MgO surface as in the known covalent Au–S bond, MgO has been studied for use as a desulfurizer to remove gaseous pollutants such as SO 2 and H 2 S , because it offers effective adsorption sites for those molecules at room temperature. − H 2 S adsorbs to the Mg 2+ sites in MgO through S . Analogously, 4-MBA and 4-NBT can be expected to bind to MgO via a deprotonated thiol formed in solution.…”

Nanostructures of some metals can sustain localized surface plasmon resonances, collective oscillations of free electrons excited by incident light. This effect results in wavelength-dependent absorption and scattering, enhancement of the incident electric field at the metal surface, and generation of hot carriers as a decay product. The enhanced electric field can be utilized to amplify the spectroscopic signal in surfaceenhanced Raman scattering (SERS), while hot carriers can be exploited for catalytic applications. In recent years, cheaper and more earth abundant alternatives to traditional plasmonic Au and Ag have gained growing attention. Here, we demonstrate the ability of plasmonic Mg nanoparticles to enhance Raman scattering and drive chemical transformations upon laser irradiation. The plasmonic properties of Mg nanoparticles are characterized at the bulk and single particle level by optical spectroscopy and scanning transmission electron microscopy coupled with electron energy-loss spectroscopy and supported by numerical simulations. SERS enhancement factors of ∼10 2 at 532 and 633 nm are obtained using 4-mercaptobenzoic acid and 4-nitrobenzenethiol. Furthermore, the reductive coupling of 4-nitrobenzenethiol to 4,4′-dimercaptoazobenzene is observed on the surface of Mg nanoparticles under 532 nm excitation in the absence of reducing agents, indicating a plasmondriven catalytic process. Once decorated with Pd, Mg nanostructures display an enhancement factor of 10 3 along with an increase in the rate of catalytic coupling. The results of this study demonstrate the successful application of plasmonic Mg nanoparticles in sensing and plasmon-enhanced catalysis.

“…On the basis of noble metal supported catalysts, some researchers proposed to combine metal components such as NiPd, LaPt, ZnPt, PtSn, NiCu, and NiSn to prepare hydroisomerization catalysts instead of single noble metal components. ,,, Yang et al prepared Pt/SAPO-11 catalyst modified by zinc by incipient wetness impregnation method and evaluated it in the hydroisomerization of n -octane. The addition of zinc led to a high dispersion of platinum.…”

Hydroisomerization catalyst is the key of the hydroisomerization process, which is a bifunctional catalyst composed of acidic support and metal components. In this work, the research progress of hydroisomerization catalysts was reviewed first from two aspects: support and metal components. The supports and metal components used to prepare hydroisomerization catalysts in recent years were introduced, and their advantages/disadvantages were summarized. SAPO-11 molecular sieve is the most commonly used and suitable support for hydroisomerization catalyst. The synthesis methods and influencing factors of SAPO-11 molecular sieves were introduced in detail, and the research progress of modification of SAPO-11 molecular sieves was summarized. Meanwhile, the effects of pore structure, acidity, and crystal size of SAPO-11 molecular sieve on SAPO-11-based hydroisomerization catalyst and their regulation methods were emphatically introduced. Finally, the development direction of n-alkane (carbon number ≤ 16) hydroisomerization catalyst and the synthesis prospect of SAPO-11 molecular sieve were summarized and prospected. This review is helpful to understand the development status of supports and metal components of hydroisomerization catalysts as well as the research status and development prospect of the synthesis of SAPO-11 molecular sieve. The future development direction of the hydroisomerization catalyst and SAPO-11 molecular sieve was summarized and put forward. It is expected to provide a reference for researchers in this field.
