Formation of hydrogen peroxide (H2O2), an oxidizing agent stronger than oxygen, by sphalerite ((Zn, Fe) S) was examined during its grinding process. It was observed that sphalerite generated H2O2 in pulp liquid during wet grinding and also when the freshly ground solids placed in water ...
hydrogenhydrogen peroxidesindolesirradiationmoleculesWHEN water is exposed to ionizing radiations the radicals H and OH are produced and these can combine either with each other to give the molecular products H 2 and H 2 O 2 , or with solutes 1 . In regions of high energy loss (such as α...
The direct synthesis of hydrogen peroxide (H2O2) from H2 and O2 over gold nanoparticles has been achieved in the past decade; however, our understanding for the mechanism is still far from complete. We present herein a density functional theory investigation of the formation mechanism of H2O2 from...

Intracellular production of superoxide radical and of hydrogen peroxide by redox active compounds Several compounds have been found capable of diverting the electron flow in Escherichia coli and thus causing increased intracellular production of O 2 and H 2O 2. One indication of this electron-shunting...
The remarkable discovery of pyrite-induced hydrogen peroxide (H2O2) provides a key step in the evolution of oxygenic photosynthesis. Here we show that H2O2 can be generated rapidly via a reaction between pyrite and H2O in the absence of dissolved oxygen. The reaction proceeds in the dark, and ...
Hydrogen or hydrogen peroxide can be generated in liquid–liquid biphasic systems, where the organic phase contains sufficiently strong electron donor (whose redox potential is lower than the potential of reversible hydrogen electrode). ... W Adamiak,J Jedraszko,O Krysiak,... - 《Journal of Phys...
