The problem of heat and mass transfer of a porous catalyst particle is considered. On the her surface, including the inner surface of the pores, an irreversibly heterogeneous first-order reaction proceeds. It has been an...

Nickel salts of Keggin heteropolytungstates with the general formula NixAyW12−yO39or40 (A = Si/P) were synthesized and studied as bulk catalytic materials or supported ones by deposition on modified and functionalized ...

The sustainable production of 5-hydroxymethylfurfural (HMF) from glucose remains a major challenge in advancing bio-based chemical platforms. Despite extensive research, achieving high HMF yields in environmentally frien...

In this paper, the catalytic behaviour of two different carbonaceous systems, commercial carbon (Cc) and synthetic carbon (Cs) functionalized with concentrated sulfuric acid (–SO3H) and with reduced aryl diazonium salt...

Abstract Selective Catalytic Reduction (SCR) helps to reduce Nitrogen Oxide (NO) emissions from diesel engines using catalytic materials made of thermally stable non-precious metals. A dual support SCR catalyst using iro...

Background: The main purpose of the naphtha reforming process is to obtain high octane naphtha, aromatic compounds and hydrogen. The catalysts are bifunctional in nature, having both acid and metal sites. The metal funct...

The oxidation of diesel soot using K/CeO2 catalysts is studied in this paper. The reaction system involved in the catalytic oxidation of soot is quite complex; therefore, the study of reaction mechanisms is particularly ...

A series of Ni supported over MgAl2O4–CeO2 catalysts have been prepared by the wet impregnation method as catalysts for steam ethanol reforming. The synthesis was performed using nitrilotriacetic acid (NTA) or citric a...

The ever-increasing production of natural gas has underscored the potential of methane-fueled solid oxide fuel cells (SOFCs) as feasible energy conversion devices. Herein, we present an internal reforming catalyst consis...

Fe-N-C catalysts are highly competitive alternatives to noble-metal catalysts for the oxygen reduction reaction (ORR). Herein, an efficient Fe and N co-doped three-dimensional graphene (Fe-N-G) catalyst that possesses a ...

The reduction of carbonyl compounds, including ketones and aldehydes, to alcohols is a fundamental and important reaction in organic synthesis. One of the most ideal methods is catalytic hydrogenation, however, the hydro...

ABSTRACT Proton exchange membrane water electrolysis (PEMWE) is a compelling route for sustainable green hydrogen production. Yet Ir‐based oxygen evolution reaction (OER) catalysts suffer from a persistent trade‐off ...

The performance of membrane electrode assembly (MEA) prepared with PtRu nanoparticles supported on a mesoporous carbon as anode catalyst are presented and compared against PtRu synthesized over Vulcan carbon. Polarizatio...

The oxidative degradation of Rhodamine B dye under ultraviolet irradiation was studied. The degradation rate was measured with using of smartphone camera. Photocatalytic degradation of the Rhodamine B dye over the P25-Ti...

Abstract This research investigates the synthesis and characterization of a unique Cy@TC-Pd complex immobilized on CdFe2O4 nanoparticles. A palladium-based catalyst, supported on magnetite nanoparticles, was successfully...

Developing cost-effective and highly durable electrocatalysts to overcome the sluggish kinetics of the oxygen reduction reaction (ORR) is critical for the promotion of proton exchange membrane fuel cells (PEMFCs). In thi...

DCM is classified among the most hazardous atmospheric pollutants and therefore, the development of safe methods for the disposal of residual DCM is of great importance. Activated carbon- supported catalysts containing p...

Near-surface molecular-beam mass spectrometry (ns-MBMS) is a highly sensitive and non-destructive method for temporal monitoring of catalytic conversions on solid surfaces, yet not widely applied in heterogeneous catalys...

Photons can be used to either monitor or induce catalysis by acting as photoexcited holes or quasi particles, which aid in water splitting reaction leading to a major step towards sustainable energy. However, the mechani...

The parabens, alkylic esters of p-hydroxybenzoic acid, were synthesized using trifluoromethanesulfonic acid immobilized on zirconium oxide (zirconia) as catalyst. The oxide was obtained by the sol–gel method, using ure...

Multiple primary malignancies (MPMs) are increasingly recognized, yet the impact of immune checkpoint inhibitors (ICIs) on the evolution of metachronous tumors remains poorly understood. Here, we report a rare case of me...
