Chars originating from the burning or pyrolysis of vegetation may significantly sorb neutral organic contaminants (NOCs). To evaluate relationship between char composition and NOC sorption, a series samples were generated by pyrolyzing wheat residue (Triticum aestivum L.) for 6 h at temperatures 300 degrees C 700 analyzed their elemental compositions, surface areas, functional groups. The then studied abilities to benzene nitrobenzene water. A commercial activated carbon was used as...
A novel CO2 capture phenomenon is observed by modifying as-prepared mesoporous silica SBA-15 (SBA(P)) with tetraethylenepentamine (TEPA), not only conserving the energy and time required for removing template, but also opening way to utilizing micelle dispersing guest species. The TEPA species dispersed within channels of SBA(P) are highly accessible molecules; moreover, hydroxyl group poly(ethylene oxide)–poly(propylene oxide)–poly(ethylene oxide) (Pluronic P123) template able modify...
The potential of black carbon as an adsorbent for pesticides in soils may be strongly influenced by the properties and environmental conditions. This study evaluated effect pH on adsorption diuron, bromoxynil, ametryne a wheat (Triticum aestivum L.) residue derived (WC) compared to commercial activated (AC). drift method indicated that WC had point zero charge 4.2, much lower than 7.8 AC. density oxygen-containing surface functional groups, measured Boehm titration, was 5.4 times higher AC,...
Multibranched pi-conjugated materials and hyperbranched polymers have received considerable interest in both academic research industrial applications because of their unusual molecular structures properties. In this communication, we provide an efficient approach to synthesize two novel multibranch compounds, which good solubility are nanosize (about 5 nm). The double bonds the compounds synthesized using solvent-free Wittig-Horner-Emmons reactions. reaction conditions simple mild. Their...
Basically super: Potassium-functionalized mesoporous γ-alumina solid superbases that have a high base strength (H−) of 27.0, well-expressed structure, and which are efficient in the isomerization 1-hexene synthesized by one-pot method. The success this method can be ascribed to flexible application K2CO3 as pH adjustor close control calcination process (see picture).

Direct generation of superbasicity on mesoporous silica SBA-15 was realized by tailoring the host-guest interaction, and calcium species were selected as guest in modifying SBA-15. The results show that could be homogeneously distributed surface Because decomposition supported nitrate apparently easier than bulk one. Surprisingly, nitrates modified (CaNS) samples exhibited with good preservation mesostructure after activation, differing from potassium loaded displayed weak basicity collapsed...
Superbasic sites have been generated on the mesoporous silica materials for first time, through a new strategy to prepare MgO-modified SBA-15 in one-pot synthesis and then disperse KNO3, possessing good textural structure of host high basic strength (H-) 27.0. The situ coated Mg species passivated silanol groups surface siliceous so that mesostructure could be reserved after composite was loaded with KNO3 activated at temperature. Existence special protection layer MgO also beneficial...
Mesoporous MFI zeolite is fabricated through impregnating a structure-directing agent into as-synthesized MCM-41 followed by dry-gel conversion to transform amorphous silica crystal. The original surfactant in the used as necessary mesoporogen direct mesopore genesis of zeolites, using process streaming spur transformation and tailoring texture mesoporous ZSM-5 adjusting Si : Al ratio source. resulting sample characterized X-ray diffraction, IR spectroscopy, TEM N2 adsorption evaluate...
Dispersion and decomposition of KNO3 on γ-alumina NaY zeolite as well Al2O3-NaY porous material were examined, the basicity these resulting solid bases characterized. was highly dispersed AlPO4-5 but difficult to decompose, due lack octahedral vacant sites in provided for insertion K+ cations. If amount loaded below monolayer dispersion threshold, it could be provoked a basic strength (H-) 18.4 alumina. When above threshold alumina, only decomposed during evacuation at 873 K generated some...
A novel solid superbase is derived from zirconia-supported potassium nitrate. Dispersion and decomposition of nitrate on zirconia were investigated compared with that alumina to explore the effect support preparation strong bases. Spontaneous dispersion capacity KNO3 ZrO2 was found be 8.1 K+ nm-2, very close a vacant site ZrO2. An unusually basicity generated through loaded began around 613 K, enhancing catalytic activity in cis-but-2-ene isomerization at 273 K. Moreover, KNO3/ZrO2 samples,...
Modification and control of surface function on porous materials have been a very promising appealing area chemistry. In this paper, the reason as to why it is impossible generate strong basicity silica titania explored in detail, consequently, new strategy was adopted overcome obstacle, not only obtain solid base derived from for first time but also environmentally benign way. Base precursor KNO3 loaded along with alumina zirconia comparison. Varied dispersion thermal decomposition behavior...
