The plain paper is of fibrous morphology, with dense fibres in the width range of 10 to 50 µm (Figure 2a) and gaps of about 50 µm. The microporous nylon membrane has a nominal pore size of 0.45 µm and is positively charged by quaternary

Graphical Abstract
  • , the creation of highly active, nanopore-coated microporous extrinsic semiconductor interfaces, their ability to provide readily accessible significant light-harvesting surface areas [5], and their ability to be transformed with selective nanostructure sites, enables sensing based on efficient electron
  • transduction. Decorated microporous arrays enable enhanced analyte diffusion to active sites [6], whereas the nanopores provide a “phase matching” region with which the modifying nanostructured materials of interest can be made to interact in a controlled manner to promote a range of interface sensitivities
  • microporous extrinsic semiconductor channels, through fractional deposition of the nanostructures. These nanostructures do not form a surface coating but rather act as independent nanostructured sites capable of strongly directed interaction with a given analyte and subsequent rapid electron transduction.

Graphical Abstract
  • photocatalytic activity is quite low. With the help of a block polymer P123, a Mg–Ta oxide powder with highly ordered mesopores was previously synthesized [11]. After removal of the P123 template by washing in water, the wormholelike microporous MgTa2O6 powder, though amorphous, showed enhanced water

  • in categories of microporous (pore diameter <2 nm), mesoporous (pore diameter 2–50 nm) and macroporous (pore diameter >50 nm) structures. The enormous diversity in nanoporous structures as well as the fact that their properties can be tuned and modified depending on the type of application is

  • microporous nature causes accessibility problems and diffusion limitations for large molecules and viscous fluids [2][18]. In the specific case of TS-1 [19], only molecules with a kinetic diameter of maximally 0.6 nm (e.g., benzene) can access the structure and reach the active sites. This drastically limits

Graphical Abstract
  • Å as compared to samples 2A and 2B. This behaviour shows that the order of the pores in sample 2C has decreased due to washing with increased solvent quantities. The ratio of the microporous to mesoporous surface area for 2C stays almost constant compared to 2A, whereas the contents of micropore
