Abstract In this study, benzimidazolium salts were synthesized by introducing a bulky N -(2-ethylhexyl) benzimidazole, while various aryl substituents were incorporated onto the second nitrogen. These salts were employed as N-heterocyclic carbene (NHC) precursors and reacted with Pd(OAc)₂ to afford a series of [PdCl₂(NHC)₂]-type palladium(II) NHC complexes. The catalytic activity of the synthesiz…

Abstract Higher alcohol synthesis was carried out over a CuFeCoK/SiO 2 catalyst with the focus on catalyst pretreatment methods. These methods consisted of either reduction with hydrogen, or reduction followed by low temperature carburization with CO, all at 300 °C. Furthermore, a third method was applied without any pretreatment of the catalyst. It was found that the pretreatment using both redu…

Abstract A series of novel air- and moisture-resistant NHC-based pyridine containing palladium PEPPSI-type Pd(II) complexes ( 2a-e ) were synthesized and characterized. The structures of all synthesized complexes were determined by various spectroscopic techniques. In addition, the structure of 2b was elucidated by single X-ray crystallography. The structural and electronic properties of 2a-e wer…

Abstract The development of high-performance, durable catalysts for polymer electrolyte membrane fuel cells (PEMFCs) is crucial to the widespread adoption of hydrogen technologies. In this context, three commercial carbon blacks (Regal 330, Vulcan XC 72R, Black Pearl 2000), each with varying surface areas and physical properties, were heat-treated at specific temperatures (1400, 1000, 1200 °C) an…
