NaY zeolite catalysts with and without potassium salt modifications were studied respect to dehydration of lactic acid acrylic acid. The selectivity for could be dramatically enhanced by modification the salts. KI-modified catalyst exhibited best catalytic performance dehydration, over which 97.6% conversion 67.9% gained at 598 K. Characterizations TGA, XRD, N2 adsorption, 27Al MAS NMR, XPS, NH3-TPD, CO2-TPD, mechanism analysis revealed that counteranions in salts exerted a significant...
The rational design of highly efficient and durable oxygen reduction reaction (ORR) catalysts is critical for the commercial application fuel cells. Herein, three-dimensional graphene (3D-G) synthesized by template method, which used coal tar pitch as carbon source nano MgO template. Then, spinel MnCo2 O4 in situ supported on 3D-G a facile hydrothermal giving /3D-G. resultant /3D-G retains multilayered mesoporous structure where nanoparticles are deposited inner walls pores 3D-G. catalyst...
High proton conductivity and sufficient stability of the polybenzimidazole membrane are important for application high-temperature exchange fuel cells (HT-PEMFCs). A series composite membranes based on crosslinked mPBI (cPBI) with cerium 2,4,6-triphosphono-1,3,5-triazine (CeTPT) were resoundingly fabricated. Novel cPBI networks tetrafunctional N,N,N′,N′-tetraglycidyl-4,4′-diaminodiphenylmethane (TGDDM) synthesized. It is noteworthy that a new conductor CeTPT was added. contained three...
Improving the comprehensive properties of high-temperature proton exchange membrane (HTPEM) under wide relative humidity (RH) is a crucial factor affecting application. For this, zirconium 4,4-[aminopropyl sulfonate (methyl phosphate)] diphenylamine sulfonic acid (Zr-PPSA), containing −SO3H suitable for transfer at high RH and -PO3H2 conduction low prepared. The highly functionalized tri-glycidyl isocyanurate (TGIC) as cross-linker poly-m-polybenzimidazole (mPBI) beneficial to improve...
The evolution of highly active dual-functional catalysts is critical to zinc–air batteries (ZAB). Herein, three-dimensional Fe–N/P-co-doped graphene (3D Fe–N/P-G) materials with a high oxygen reduction reaction (ORR) and (OER) response are prepared by molten salt protection method KCl. 3D Fe–N/P-G exhibits large Brunauer–Emmett–Teller (BET) surface area dense network pores for improved mass transfer efficiency. addition P atoms able produce synergistic effect that improves the ORR catalytic...
Abstract Considerable effort has been applied to the development of new processes and catalysts for cellulose conversion valuable platform chemicals. Isosorbide is among most interesting products as it can be a monomer building block future replacement fossil resource‐based products. A sustainable method isosorbide production from presented in this work. The strategy relies on bifunctional Ru catalyst supported mesoporous niobium phosphate H 2 atmosphere under pressure without further...
In this study, an experimental investigation was conducted on the mechanical properties of lightweight aggregate concrete (LWAC) with different chopped fibers, including basalt fiber (BF) and polyacrylonitrile (PANF). The LWAC performance studied in regard to compressive strength, splitting tensile strength shear at age 28 days. addition, oven-dried density water absorption were measured as well confirm whether specimens match requirement standard. total, seven mixture groups designed...
Increasing the proton-conducting durability and structural stability of acid-doped polybenzimidazole (PBI) proton exchange membranes (PEMs) is helpful for their application at high temperatures. However, these tend to show a swelling degree easy leaching acidic conductors. To effectively improve comprehensive performance PEMs, multifunctional cross-linkable conductor (TTPSA) used form high-temperature PEM (HTPEM) by multiple cross-linking with chloromethylated polyetherimide (CMPEI) mPBI....
The mine water environment in underground reservoirs poses great threat to the durability of artificial concrete dams, mainly due coupled sulfate and drying-wetting cycles.
