A process for producing oxidized organic chemical products from various organic chemical feedstocks utilizing as oxidant hydrogen peroxide (H2O2) produced by noble metal nanocatalysis with high selectivity at low hydrogen concentration. The organic chemical oxidation process step can optionally be carried out in situ concurrent with the production of hydrogen peroxide or in a two stage process. In the two stage process, the hydrogen peroxide intermediate is directly produced by noble metal nanocatalysis from hydrogen and oxygen feeds plus a suitable solvent in a first catalytic reaction step. An organic chemical feedstock and the hydrogen peroxide intermediate and solvent solution are fed into a second catalytic reactor to produce an oxidized organic chemical product.
