Dearomatization of the Kerosene Fraction: Kinetic Studies

Received: 09 January 2022;  Published: 28 June 2022;  doi: 10.21926/cr.2202017

Abstract

The kinetics of dearomatization of a kerosene fraction processed using a zeolite catalyst (0.9 HZSM-5) at different temperatures (160-200°C), the molar ratio between the aromatic hydrocarbons present in the kerosene fraction and n-decene (1:(0.5-4)), and the reaction time (1-3 h [...]

3D Fe3O4-decorated Nitrogen-doped Graphene Aerogel as a Highly Durable Electrocatalyst for Oxygen Reduction Reactions

Received: 29 April 2022;  Published: 21 June 2022;  doi: 10.21926/cr.2202016

Abstract

The rational design of efficient electrocatalysts for oxygen reduction reaction (ORR) is the key to developing fuel cells and metal-air batteries. Carbon-supported iron-based materials, as the most promising electrocatalysts for ORR, have drawn much attention as they are cost-effective and exhibit h [...]

Synthesis of a Solid Base Catalyst Formed from Zinc(II) Acetylacetonate and Consisting of MgO Modified with ZnO

Received: 28 April 2022;  Published: 06 June 2022;  doi: 10.21926/cr.2202015

Abstract

Solid base catalysts consisting of MgO modified with 10 mol% ZnO (ZnO/MgO) were prepared by depositing zinc(II) acetylacetonate (Zn(acac)2) in polar and nonpolar organic solvents on the surface of MgO and Mg(OH)2. The process was followed by thermal deco [...]

Visible-Light-Induced Formation of Aromatic Ketones: A Metal-Free C−H Oxygenation Process in Air under Room Temperature

Received: 01 April 2022;  Published: 10 May 2022;  doi: 10.21926/cr.2202014

Abstract

The process of light-induced C-H oxygenation is of high interest as it can be used for the construction of oxygenated compounds. Herein, we report a mild and general method for the efficient synthesis of aromatic ketones following the process of metal-free C-H oxygenation. With air as the oxidant, h [...]

Lipases: Sources of Acquisition, Ways of Production, and Recent Applications

Received: 16 February 2022;  Published: 07 May 2022;  doi: 10.21926/cr.2202013

Abstract

Enzymes are extensively used in biotechnological processes in several areas of industry. They are sustainable and safe, and their specificity is another characteristic that improves the performance in the process. Among enzymes, lipase is relevant due to the ability to play different roles in the in [...]

Recent Advances in the Application of Perovskite Catalysts in the Dry Reforming of Methane

Received: 29 January 2022;  Published: 26 April 2022;  doi: 10.21926/cr.2202012

Abstract

The use of the dry reforming of methane (DRM) to convert the two principal greenhouse gases, methane and carbon dioxide, to syngas (a mixture of H2 and CO) has attracted increasing attention in recent years. However, the DRM reaction suffers from the twin disadvant [...]

Pd-Cu Bimetallic Based Catalysts for Nitrate Remediation in Water: Synthesis, Characterization, and the Influence of Supports

Received: 29 January 2022;  Published: 21 April 2022;  doi: 10.21926/cr.2202011

Abstract

The use of Pd-Cu bimetallic catalysts in the reduction of aqueous nitrate ions by hydrogen was studied. The catalysts were supported on multi-walled carbon nanotubes (MWCNTs), activated carbon (AC), and Titania, and the influence of the support on the nitrate reduction activity in water was then inv [...]

A New Chiral Cyclopalladated Ferrocenylimine Self-assembly Polymeric Film supported on Silicon for Heck and Suzuki-coupling Reactions

Received: 21 March 2022;  Published: 14 April 2022;  doi: 10.21926/cr.2202010

Abstract

A new chiral cyclopalladated ferrocenyl imine catalyst (called 4a2) was designed and synthesized, and its self-assembly catalytic polymeric brush supported on silicon (denoted as Si@PB4a2) was also fabricated by surface-initiated atom transfer radical polymerization (ATRP) and characterized. The cat [...]

Hierarchical MFI Zeolite Catalysts: How to Determine Their Textural Properties?-A Comparative Study

Received: 26 January 2022;  Published: 14 April 2022;  doi: 10.21926/cr.2202009

Abstract

It is important to elucidate the role of the surface areas and pore volumes of hierarchical zeolites to understand their behavior as catalysts. Micro-and mesopore surface areas and volumes of the hierarchical MFI (Mobil Five zeolites) were assessed following several methods: (i) [...]
