The largest producers find out here of rhodium contain South Africa, copyright and Russia, wherever big normal deposits of rhodium steel are present [two].
Chemical market is, equally as my aged investigate group, serious about using rhodium to make molecules. Rhodium was, as an example, right until not too long ago the primary option as catalysts in generating considered one of mankind's oldest chemicals, acetic acid. It supplanted its periodic table upstairs neighbour cobalt in this process in the late 1960s in a prime illustration of precisely what is now know as green chemistry generating the procedure additional Vitality economical and making significantly less by-goods.
