“…The future in this area of research could come from continuous mesoporous carbon films that start to emerge 138, 142, 148, 169, 184, which would eventually allow a better control of the protein‐material interactions. Proper engineering of the material in a way permitting better control of the immobilization of the proteins is notably necessary for tuning their conformation when attached to the electrode surface.…”

“…Mesoporous materials applied to electrochemical biosensors can be classified in three main categories, silica‐based materials 97–137, carbon‐based materials 113, 138–178, 76, 179–184 and metal oxides other than silica 121, 130, 185, 73, 186–198, 75, 74, 199–202. A mesoporous polymer, i.e., polyacrylamide, was also namely reported 203, but in this latter example, the organic template was kept in the membrane and no information on the porosity was given.…”

This review (239 references) is dealing with the use of mesoporous materials in the field of electrochemical enzymatic biosensors. After a brief discussion on the interest of mesoporous materials for electrochemical biosensing, a presentation of the various types of inorganic and organic‐inorganic hybrid mesostructures used to date in the elaboration of enzymatic bioelectrodes is given and the main bioelectrode configurations are described. The various biosensor applications are then summarized on the basis of a comprehensive table and some representative illustrations. The main detection schemes developed in the field are based on amperometry and mediated electrocatalysis, as well as some on spectroelectrochemistry.

“…This progress report presents an overview of recent studies on the synthesis, properties, and applications of porous materials with macroscopically oriented structures ( Table 1 ). The scope of this report is limited to porous materials with nano‐ or mesoscale periodic channels constructed by supramolecular self‐assembly of atomic and/or molecular components, such as zeolites (Section ), MOFs (Section ), mesoporous oxides (Section ), and polymers based on liquid crystals (LCs) (Section ) . In other words, porous materials produced by physical processes, such as anodic aluminum oxides or porous silicones, are beyond the scope of this report.…”

Porous materials with molecular‐sized periodic structures, as exemplified by zeolites, metal–organic frameworks, or mesoporous silica, have attracted increasing attention due to their range of applications in storage, sensing, separation, and transformation of small molecules. Although the components of such porous materials have a tendency to pack in unidirectionally oriented periodic structures, such ideal types of packing cannot continue indefinitely, generally ceasing when they reach a micrometer scale. Consequently, most porous materials are composed of multiple randomly oriented domains, and overall behave as isotropic materials from a macroscopic viewpoint. However, if their channels could be unidirectionally oriented over a macroscopic scale, the resultant porous materials might serve as powerful tools for manipulating molecules. Guest molecules captured in macroscopically oriented channels would have their positions and directions well‐defined, so that molecular events in the channels would proceed in a highly controlled manner. To realize such an ideal situation, numerous efforts have been made to develop various porous materials with macroscopically oriented channels. An overview of recent studies on the synthesis, properties, and applications of macroscopically oriented porous materials is presented.

“…The synthesis of Pt‐free carbon coatings with high surface, controlled porosity and pore connectivity as well as a high electrical conductivity has been reported in the form of ordered mesoporous carbon (OMC) films. Control over the materials pore structure is obtained by the use of amphiphilic molecules that act as structure‐directing agents . Typical syntheses start from low‐molecular‐weight precursor (e.g., resins consisting of a polycondensation product of phenol, resorcinol or phloroglucinol with formaldehyde) and a template molecule (e.g., triblock copolymer) dispersed in an organic solvent.…”

Nafion‐Free Carbon‐Supported Electrocatalysts with Superior Hydrogen Evolution Reaction Performance by Soft Templating

et al. 2016

Efficient water electrolysis requires electrode coatings with high catalytic activity. Platinum efficiently catalyzes the hydrogen evolution reaction in acidic environments, but is a rare and expensive metal. The activity achieved per metal atom can be increased if small Pt particles are dispersed onto electrically conductive, highly accessible and stable support materials. However, the addition of Nafion, a typical binder material used in the manufacture of electrode coatings, can decrease catalytic activity by the blocking of pores and active surface sites. A new approach is reported for the direct synthesis of highly active Nafion‐free Pt/C catalyst films consisting of small Pt nanoparticles supported in size‐controlled mesopores of a conductive carbon film. The synthesis relies on the co‐deposition of suitable Pt and C precursors in the presence of polymer micelles, which act as pore templates. Subsequent carbonization in an inert atmosphere produces porous catalyst films with controlled film thickness, pore size and particle size. The catalysts clearly outperform all Nafion‐based Pt/C catalysts reported in the literature, particularly at high current densities.
