This provides a flexible, porous, dissolvable solid sheet article containing a cationic surfactant.

Flexible, porous, dissolvable solid sheet articles containing cationic surfactant

It relates to a type of catalysts for preparation of chirality-selective and conductivity-selective single-walled carbon nanotubes. The catalysts have chemical compositions of AB, wherein A is the metal tungsten (W), B stands for one or more metals selected from a group consisting of the transition metals manganese, iron, cobalt, copper, zinc, chromium, vanadium, rhodium, ruthenium, palladium, platinum, gold, silver, osmium, iridium, and the lanthanide rare earth metals, and y is in the range of 0.01-20.0. This catalyst can be used to catalyze the growth of single-walled carbon nanotubes with desired chirality and conductivity.

This invention relates to the cleaning of flue gas released from various combustion processes, particularly a surface deposition NH&#x2014;SCR honeycomb catalyst and its preparation method. The catalyst is composed of framework material, TiO, VOand WO, wherein the framework material is composed of clay, coal ash, mineral waste residue or their mixture. The mass fractions for framework material, TiO, VO, and WOare 60 wt. % to 80 wt. %, 13 wt. % to 33 wt. %, 1 wt. % to 5 wt. %, and 0.1 wt. % to 2 wt. %, respectively. The nano VO&#x2014;WO&#x2014;TiOparticles were deposited on the surface of particle pore or honeycomb, and the performance of the catalyst could be greatly improved.
