“…1405,[1410][1411][1412] An obvious inspiration when designing imprinted polymers for catalytic function is to incorporate enzyme-like functionality, with chemical groupings in the sites that mimic natural amino acids and which utilize noncovalent interactions to bind substrates and catalyse reactions. These catalytic MIPs are generally prepared with a transition state analogue (TSA) as the template species, such that the imprinted site is designed to stabilise an intermediate region on the reaction pathway from substrate to product, thus lowering the overall activation energy for the process.…”

Over 1450 references to original papers, reviews and monographs have herein been collected to document the development of molecular imprinting science and technology from the serendipitous discovery of Polyakov in 1931 to recent attempts to implement and understand the principles underlying the technique and its use in a range of application areas. In the presentation of the assembled references, a section presenting reviews and monographs covering the area is followed by papers dealing with fundamental aspects of molecular imprinting and the development of novel polymer formats. Thereafter, literature describing attempts to apply these polymeric materials to a range of application areas is presented.

“…Functionalized latex particles have proved viable catalysts for a variety of oxidation and hydrolysis reactions in which high electrolyte concentrations are not required. Functional groups have included sulfonic acids, , a primary amine, and imidazoles for ester hydrolysis and cobalt complexes for autoxidation of organic compounds. − Catalysts are sought for environmental use, which would be capable of oxidizing all organic compounds in industrial wastewater to carbon dioxide, as well as for use in chemical manufacturing processes. Chemical reactions in aqueous colloidal dispersions are related to important reactions in living organisms; for example, metalloporphyrins have been used to mimic the action of natural oxygenases …”

Porous polymer films have been prepared from poly(butyl methacrylate) latex particles with surface sulfonate groups and been shown to retain up to 90% of the catalytic capacity of the original latex particles. Advantages of latex films over latex particles as reactive surfaces include easier removal from the reaction medium and easier cleaning/rejuvenation of the polymer films. The films have been characterized by specific surface area, mercury porosimetry, and conductometric titration. Reactivity was evaluated for the acid-catalyzed hydrolysis of ethyl methanoate.

“…The loaded zeolite photocatalysts were suspended in 10 mL of an aqueous solution of Na2S-9H20 (0.23 M, Alfa or Aldrich) and Na2S03 (0.36 M, Fisher) held in a Pyrex test tube. The test tubes were sealed with wired (4) Veno, A.; Kakuta, N.; Park, K. H.; Findlayson, M. F.; Bard, A. J.; Campion, A.; Fox, . A.; Webber, S. E.; White, J. M. J. Phys.…”

therefore may not be able to abstract and accommodate the hydride from the carbonyl carbon. In this case, the eliminated hydrides from the carbonyl carbon atoms may attack adsorbed formaldehyde molecules to form surface methoxides. ConclusionsFormaldehyde reacts on basic sites on MgO surfaces to form both CH,O(ad) and HCOO(ad) species via the Cannizzaro reaction. This reaction may be suppressed by preadsorption of Bransted acids such as methanol and water. The observation of the Cannizzaro reaction on clean oxide surfaces, including both thin oxide films on Mg(0001) and the MgO(100) surface, suggests that this reaction can occur on basic MgO sites of high coordination number.
