“…Similar catalysts for selective oxidation of organic molecules would be appealing, but effective examples are rare. Adam’s catalyst (PtO 2 ) is typically used as a hydrogenation catalyst, but it also mediates aerobic oxidation of primary alcohols to carboxylic acids . A high catalyst loading is often required in the latter application (e.g., 0.6 equiv of Pt), and other reagents, such as the Jones reagent (CrO 3 /H 2 SO 4 ) or bleach/TEMPO, tend to be more synthetically reliable.…”

Efficient aerobic oxidative methyl esterification of primary alcohols has been achieved with a heterogeneous catalyst consisting of 1 mol % Pd/charcoal (5 wt %) in combination with bismuth(III) nitrate and tellurium metal. The Bi and Te additives significantly increase the reaction rate, selectivity, and overall product yields. This readily accessible catalyst system exhibits a broad substrate scope and is effective with both activated (benzylic) and unactivated (aliphatic) alcohols bearing diverse functional groups.

Abstract The potential sources of various metals in chemical and petrochemical processes are discussed. Special emphasis is put on the catalysts used in the industry. Their main applications, compositions, especially metal contents are presented both for fresh and spent ones. The focus is on the main types of metals used in catalysts: the platinum-group metals, the rare-earth elements, and the variety of transition metals. The analysis suggested that chemical and petrochemical sectors can be considered as the secondary source of metals. Because the utilization of spent refinery catalysts for metal recovery is potentially viable, different methods were applied. The conventional approaches used in metal reclamation as hydrometallurgy and pyrometallurgy, as well as new methods include bioleaching, were described. Some industrial solutions for metal recovery from spent solution were also presented.
