Abstract:
To satisfy the need for catalyst materials with high activity, selectivity, and stability for energy conversion, material design and discovery guided by theoretical insights are a necessity. In the past decades, the rise in theoretical investigations into the properties of catalyst materials, reaction mechanisms, and catalyst design principles has shed light on the catalysis field. Quantitative structure–activity relationships have been developed through incorporating spectroscopic simulations, electronic structure calculations, and reaction mechanistic studies. In this review, we report the s

The characteristics of the electric field are determined, which set the values of the characteristics of the field catalysis. Field catalysis and field catalyst do not fit into the traditional definition of catalysis and catalyst, which may require a revision of the terminology of catalysis. The field is a more versatile catalyst compared to material catalysts, both in terms of its application to a wider range of chemical reactions, and in the ability to control the rate and

Abstract:
Confined microenvironments formed in heterogeneous catalysts have recently been recognized as equally important as catalytically active sites. Understanding the fundamentals of confined catalysis has become an important topic in heterogeneous catalysis. Well-defined 2D space between a catalyst surface and a 2D material overlayer provides an ideal microenvironment to explore the confined catalysis experimentally and theoretically. Using density functional theory calculations, we reveal that adsorption of atoms and molecules on a Pt(111) surface always has been weakened under monolayer graphene,

Abstract:
Nanoconfinement in porous catalysts may induce reactant concentration gradients inside the pores due to local conversion. This leads to inefficient active material use since parts of the catalyst may be trapped in an inactive state. Experimentally, these effects remain unstudied due to material complexity and required high spatial resolution. Here, we have nanofabricated quasi–two-dimensional mimics of porous catalysts, which combine the traits of nanofluidics with single particle plasmonics and online mass spectrometry readout. Enabled by single particle resolution at operando conditions duri

Spent nickel catalyst will be harmful to the environment if it is not processed or used properly. In fact, this waste still has a high nickel content. The treatment of spent nickel catalysts has been widely reported, but limited to nickel extraction.

Consequently, nickel from spent nickel catalysts could be developed as secondary source for lithium-ion battery cathode.

Phosphotungstic acid H3[PMo12O40](PTA) with the Keggin structure has become well known as a solid superacid with pKa≈-13. Such a strong acidity is caused by delocalization of the negative charge of the anion on many oxygen atoms over the surface of the Keggin structure. High acidity of PTA and its good solubility in water and other polar solvents enables its use as a highly active homogeneous catalyst. However, in spite of relatively higher reaction rate, homogeneous catalysis has various drawbacks that limit its practical application. The main drawback is the difficult and expensive removal o

Abstract:
Abstract PDC drill bits are the primary drilling tools for oil and gas in most of formations. In a PDC drill bit, PDC cutters are key cutting components to engage with these formations. However, there is often a big challenge for today's PDC drill bits when drilling very hard and abrasive formation. The main weakness in the PDC cutter is due to the unavoidable use of metallic catalyst which is used to bond the diamond grains in the PDC cutters. The thermal expansion of the metallic catalysts resulting from high frictional heat at the cutter/rock interface during drilling operation is higher th

Abstract:
Abstract This paper presents the results of our investigation on new catalyst materials for Proton-exchange membrane (PEM) fuel cells. The sluggish kinetics of the oxygen reduction reaction (ORR) and poor electrochemical durability of platinum-based catalysts necessitated the study of new materials. Recently, pyrolytic transition metal nitrogen-carbon material (M-N-C) based catalysts have gained considerable attention for their unique electronic structure and other physical properties, which can facilitate better ionic and electronic conductivities. Specifically, nickel-nitrogen-carbon (Ni-N-C

Abstract:
Oxidation catalysts are often utilized to reduce carbon monoxide, formaldehyde, and volatile organic compounds in order to meet emissions regulations for large bore natural gas engines. These catalysts degrade over time and need to be replaced or regenerated to maintain emissions compliance. This work evaluates the effectiveness of catalyst regeneration, or catalyst washing. The evaluation is performed by utilizing field and laboratory slip streams combined with catalyst module performance (reduction efficiency) measurements and catalyst material surface analysis to quantify catalyst poisons.

Abstract:
Oxidation catalysts are typically specified to reduce carbon monoxide (CO), Hazardous Air Pollutants (HAPs) and/or Volatile Organic Compounds (VOCs) from lean-burn engines. The application of catalysts to HAPs and VOC destruction is more recent, so greater effort has been placed on optimizing for CO oxidation than HAPs or VOC oxidation. In general, the catalysts consist of a porous, high surface area -alumina carrier material on a ceramic (typically cordierite) or stainless steel substrate. Although the alumina has some effectiveness in oxidation at high temperature, its primary role here is t

Abstract:
Bacterial cellulose (BC) was investigated as a novel material for preparing activated carbons. BC was dried by heating and it was carbonized with a chemical activation process using phosphoric acid (H₃PO₄) as an activating agent at different temperatures (400, 500 and 600 °C). The properties of the activated carbons were characterized such as chemical property, structure, pore size, thermal property by Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), N₂ -physisorption (BET), scanning electron microscopy (SEM) , thermal gravimetric (TGA).

Abstract:
It is common practice to incorporate low molecular weight molecules, known as chain extenders, to enhance the performance of polyurethane (PU) material. They usually increase the phase separation between the soft and hard domains, which has a significant impact on the density of hydrogen bonds. Aminoalcohols, molecules with both hydroxyl and amine functional groups, are important building blocks in the synthesis of pharmaceuticals but are also widely used in cosmetics or paints and coatings. Easily derived from abundant natural sources, such as amino acids, aminoalcohols align with the need fo

Abstract:
The sol-gel transition of tetra-coordinated spirosilicate via hydrolysis and condensation under acidic and basic conditions is examined to elucidate the effect of catalyst, reaction time and temperature on the properties of obtained gel. The main advantage of this process is the low temperature employed, producing a solid network with a high specific surface area. FTIR spectroscopy and TGA analysis were used to characterize the formation of siloxane bonds (Si-O-Si). It is found that spirosilicate can be hydrolyzed under both acid and base catalyzed conditions.
