Fibrous silica ZSM-5 (FZSM-5) with a novel dendrimeric morphology was synthesized using CTAB-based microemulsion system. The dendrimers increased the active site accessibility and enhanced catalytic activity for large molecule hydrocracking ethylbenzene dehydrogenation.
Abstract BACKGROUND Recycling of spent platinum group metals (PGMs) has attracted much attention in order to overcome the problems associated with low natural abundance these resources. To recycle such metals, efficient hydrometallurgical processes are required. improve efficiency processes, we have designed a new phosphonium‐based ionic liquid as an extraction solvent. This paper reports on potential use for and separation PGMs, namely Pt(IV), Pd(II), Rh(III). RESULTS An liquid,...
In today's world, the utilization of electronic devices, particularly mobile phones, has seen a remarkable surge and they are valuable source recovery precious metals. The current study reports on physical chemical processing phone waste into leachate, followed by metals, using ionic liquid functionalized activated carbon (ACF). process was explored both in batch column study. presence base metals final leachate minimized employing multi-stage leaching, leading to more efficient purification...
The recovery of platinum group metals (PGMs) from automotive exhaust catalysts is important, and hydrometallurgical extraction an effective approach. In the present study, a newly designed phosphonium-based ionic liquid (IL) was applied to separation PGMs automobile catalyst leach liquor in conjunction with varying pH levels. This IL, trioctyldodecyl phosphonium chloride (P8,8,8,12Cl), allows quantitative Pd(II) at any HCl concentration, almost 80% removal Rh(III) 1 mol L–1 after two...
In this study, we report the separation of Pd(II) and Rh(III) in a chloride solution using polymer inclusion membrane (PIM). We designed trioctyl(dodecyl) phosphonium (P88812Cl) ionic liquid as metal carrier for PIM system. The effects composition experimental conditions were systematically investigated. concentrations hydrochloric acid feed thiourea receiving found to play crucial role success selective separation. Under optimized conditions, could be effectively separated from with 98%...
Platinum group metals (PGMs) play an important role in the automotive industry as key components of exhaust catalysts. Recycling PGMs from secondary resources, such waste products, is encouraged to ensure their sustainability. A highly efficient and environmentally benign technique for separation currently required. In present study, recovery a spent catalyst was investigated using trioctyldodecyl phosphonium chloride (P8,8,8,12Cl) ionic liquid (IL) PGM extraction solvent. First, leaching...
Mutual separation of platinum group metals (PGMs) is a particularly challenging issue in metal recovery technology. In this study, we report the successful Pt(IV), Pd(II), and Rh(III) by sequential transport through polymer inclusion membranes (PIMs) containing ionic liquid trioctyl(dodecyl) phosphonium chloride (P88812Cl) as carrier. This study describes screening suitable receiving solutions, optimization operating conditions, establishing possible mechanism, evaluation membrane stability....
The advantageous properties of ionic liquids (ILs) have put them in the spotlight recent years as durable and environmentally friendly solvents compared with conventional organic solvents. applications ILs been expanding various fields, including extraction separation metals. Platinum group metals (PGMs) are attractive targets for recovery using IL systems. In years, shown excellent performance PGM extraction. this review, we focus on progress solvent recovery. Although application is still...
In this modern time, precious metals hold an important place in human life. Secondary resources, such as waste, have become essential alternative source to supplant these metals. Ionic liquids (ILs) demonstrated excellent performance recovering Immobilizing ILs onto a solid support mesoporous silica simultaneously diminishes the IL drawback, enhances adsorption capacity, and improves reusability. Thus, chemically enhanced mesostructured nanoparticles with trioctylodecylphosphonium chloride...
