For the application of formic acid as a liquid organic hydrogen carrier, development of efficient catalysts for dehydrogenation of formic acid is a challenging topic, and most studies have so far focused on the composition of metals and supports, the size effect of metal nanoparticles, and surface chemistry of supports. Another influential factor is highly desired to overcome the current limita...

Phosphorus from excess fertilizers and detergents ends up washing into lakes, creeks, and rivers. This overabundance of phosphorus causes excessive aquatic plant and algae growth and depletes the dissolved oxygen supply in the water. In this study, aluminum-impregnated mesoporous adsorbents were tested for their ability to remove phosphate from water. The surface structure of the materials was ...

in  this  study,  amino  functional  groups  were  chemically  bonded  to  the  surface  of  newly synthesized  kit-6  mesoporous  magnetite  nanoparticles  (mmnps)  by  post-toluene  reflux synthesis method.  this method  treats  calcined mesoporous  nanoparticles with  the  functional organosilanes.  physical  and  chemical  structures  of  the  synthesized  mesoporous  magnetite nanoparticle...

The bifunctionalized mesoporous organosilica spheres with trans-(1R,2R)-diaminocyclohexane (DACH) in the pore were synthesized and their application as chiral stationary phase in high-performance liquid chromatography (HPLC) was demonstrated. Bifunctionalized mesoporous organosilica spheres with narrow particle size distribution of 5-7 microm were prepared by the co-condensation of N-[3-(trieth...

The mesoporous ferrosilicates with high content of framework iron species have been synthesized under mild acidic conditions (pH 4.4, buffer solution) by co-condensation of iron acetylacetonate and a mixture of tetraethoxysilane (TEOS) and sodium silicate using block copolymer Pluronic P123 as the template. The XRD, N2 sorption and TEM results show that the materials have well-ordered, two-dime...

A novel enzyme immobilization approach was used to generate mesoporous enzymes-silica composite microparticles by co-entrapping gelatinized starch and cross-linked phenylalanine ammonia lyase (PAL) aggregates (CLEAs) containing gelatinized starch into biomemitic silica and subsequently removing the starch by α-amylase treatment. During the preparation process, the gelatinzed starch served as a ...

In recent years, hybrid organic–inorganic perovskite light absorbers have attracted much attention in the field of solar cells due to their optoelectronic characteristics that enable high power conversion efficiencies. Perovskite-based solar cells’ efficiency has increased dramatically from 3.8% to more than 20% in just a few years, making them a promising low-cost alternative for photovoltaic ...

We discuss the use of nuclear magnetic resonance (NMR) spectroscopy to investigate the physical state of the eutectic composition of LiBH4-Ca(BH4)2 (LC) infiltrated into mesoporous scaffolds and the interface effect of various scaffolds. Eutectic melting and the melt infiltration of mixed borohydrides were observed through in situ NMR. In situ and ex situ NMR results for LC mixed with mesoporou...
