Preparation of uniform magnetic recoverable catalyst microspheres with hierarchically mesoporous structure by using porous polymer microsphere template
Merging nanoparticles with different functions into a single microsphere can exhibit profound impact on various applications. However, retaining the unique properties of each component after integration has proven to be a significant challenge. Our previous research demonstrated a facile method to incorporate magnetic nanoparticles into porous silica microspheres. Here, we report the fabricatio...
متن کاملDesign and Fabrication of Hierarchically Porous Carbon with a Template-free Method
Fabrication of hierarchically porous carbon materials (HPCs) with high surface area and pore volume has always been pursued. However, the currently effective template methods and acid/base activation strategies suffer from the drawbacks of either high costs or tedious steps. Herein, HPCs with 3D macro-mesopores and short-range meso-micropores were fabricated via an easy and sustainable two-step...
متن کاملSynthesis of wide band gap nanocrystalline NiO powder via a sonochemical method.
A sonochemistry-based synthesis method was used to produce nanocrystalline nickel oxide powder with ≈ 20 nm average crystallite diameter from Ni(OH)(2) precursor. Ultrasound waves were applied to the primary solution to intensify the Ni(OH)(2) precipitation. Dried precipitates were calcined at 320°C to form nanocrystalline NiO particles. The morphology of the produced powder was characterized b...
متن کاملSynthesis of Hierarchically Porous Zeolites for Catalytic Applications
Introduction Hierarchical pore systems (HPSs) are defined by the different porosity levels in two or multiple length scales. HPSs can be found ubiquitously in nature and human artworks, such as the circularly systems of plants and animals, the cellular shells of diatoms, animal nerve systems, man-made architectures, and traffic systems in modern cities. HPSs are naturally or artificially design...
متن کاملSynthesis and Characterization of Hierarchically Porous Silica with Poplar Tissue as Template with Assistance of Supercritical Co2
Hierarchically porous silica samples, ranging from mesopores to macropores, were prepared by “nanoscale casting using supercritical (SC) fluids” (NCSCF) technology and bionics, achieving a biomineralization process in an environmentally friendly and efficient way. These wood-templated SiO2 samples, having special hierarchical pore sizes from 3.3 nm up to 50 μm, were obtained with SC-CO2 precurs...
