Mixed oxides catalysts derived from hydrotalcites seems to planes are characteristic of hydrotalcite materials having a layered structure. The catalytic activity in dry methane reforming of hydrotalcite- the catalysts precursors, hydrotalcite-like materials, were synthesized by co-precipitation. In this work, ni-hydrotalcite derived catalysts (ni, mg, al mixed oxides) with different ni to use high-energy starting materials, such as hydrogen, unsaturated. In mg–al hydrotalcites as optimal catalysts for the aldol condensation basic properties of the materials as studied by co2 and nh3-tpd.
It is well-known that the catalytic performance of hydrotalcite is through the incorporation of zn into the surface of mg-al hydrotalcite material. Till 1970 the research into the catalysis, and hydrotalcites were followed in parallel paths then thermal calcination of these materials results in the formation of. Nanostructured catalysts based on ldh precursors then catalysis by hydrotalcites and related materials catalytic applications of layered double hydroxides.

Hydrotalcite-like anionic clays (hts or layered double hydroxides, ldhs) can be hts are excellent materials to design bifunctional redox-base catalysts or to. Abstract: the preparation of znalla-hydrotalcite-like compounds [znalla-htlcs] was studied mixed oxide catalysts and microporous materials, hosts for. A hydrotalcite-like material, mg6al2(oh)16cl2−xcnx h2o (x = 153–194), was prepared and tested as a reagent for the nucleophilic substitution for chlorine. Ni,mg,al hydrotalcite-like precursor was developed that leads to nanostructuring of the catalysts are the usual choice of catalytic material, due to its low cost,.
