A series of bifunctional Zr-SBA-15_x varying molar Si/Zr ratio x (15–730) with isolated Lewis and Brønsted acid sites were prepared by an in situ synthesis procedure applied to the one-pot conversion furfural (FUR) gamma-valerolactone (GVL). These catalysts detailed characterized XRF, XRD, N2 physisorption, FTIR, SEM, TEM, NH3-TPD, pyridine-DRIFT techniques. On all these catalysts, FUR was higher than 99%, while GVL selectivity first increased then decreased decreasing x. Zr-SBA-15_25...
Abstract The acceptorless dehydrogenation reaction is a sustainable and atom‐economical methodology in organic synthesis, resulting the byproducts of only hydrogen or water. Herein, robust Co−Si/CN catalyst (derived from ZIF@SiO 2 composite) has been synthesized through one‐step assembly process via pyrolysis etching. This employed for dehydrogenative coupling 2‐aminoalcohols with secondary alcohols, enabling efficient conversion various substrates into desired quinoline pyridine derivatives...
: The design and synthesis of an efficient Ni-MgO solid solution catalyst with specific morphology for the hydrogenation nitroarenes is highly required. In this work, a banana-like incorporation carbon (termed as Ni/MgO-C) has been synthesized via MOFs-templating strategy one-step pyrolysis bimetallic Ni-Mg@MOFs. developed Ni/MgO-C was applied to reaction, which exhibited good performance corresponding arylamines. Ni-Mg@MOFs served precursor preparation catalysts that could improve...
Through in-depth study of the properties and reaction mechanisms catalysts, it is possible to better optimize catalytic systems improve efficiency selectivity. This remains one challenges in field catalysis. Therefore, research design catalysts play crucial roles understanding optimizing mechanisms. A robust 2D zinc-based MOFs (Zn-HA) supported Co(II) ion catalyst (Zn-HA@Co) has been designed synthesized via a coordination-assisted strategy for β-alkylation secondary alcohols with primary...
Vanadia supported on SBA-15 significantly enhanced the reaction rate of EL in oxidation to EP.
Pavement cracking is a primary cause of early damage in asphalt pavements, and fiber-reinforcement technology an effective method for enhancing the anti-cracking performance pavement mixtures. However, due to multi-scale dispersed structure mixtures, it challenging address with single fiber type or fibers same scale. To investigate toughening mechanisms behavior hybrid-fiber-modified we analyzed fracture process these mixtures using combination basalt calcium sulfate whisker hybrid...
Titanium alloys have attracted more attention as biomaterials. Plasma ion implantation is utilized in this paper to improve the bioactivity, wear resistance, and corrosion resistance of Ti6Al4V alloy. As an effective surface-modification technique, plasma eliminates limitation light sight compared conventional beam implantation. The excited by RF power ranging from 200 400 W with sample bias 20 kV. results show improvement hardness, tribological properties. Longer treatment time or higher...
This paper introduces several kinds of reactors for methane catalytic combustion. Furthermore, we briefly summarize and compare advantages, disadvantages, research progresses experimental applications fixed-bed reactor, fluidized-bed reverse flow micro-channel reactor membrane
In plasma immersion ion implantation (PIII) of planar samples such as silicon wafers in the PIII-ion-cut well separation by oxygen (SPIMOX) processes, only important ions are ones arriving at top surface. Ions implanted into other surfaces are, fact, undesirable they reduce efficiency power supply and source give rise to metallic contamination. We have demonstrated direct-current PIII (DC-PIII) using a grounded grid separate vacuum chamber for sample implantation. The advantages include...
Catalytic combustion technology can effectively reduce the temperature of reaction and significantly inhibit formation NOx. Perovskites catalyst materials have high stability, varied chemical composition, low cost etc. A combination catalytic perovskite has great significance for energy industry environment protection. However, improving lower activity thermostability performance is still major problem. Some researchers improved stability catalysts methane by different preparation methods....
