In a method and device for conversion of water into hydrogen peroxide (H.sub.2O.sub.2), a corona discharge zone is generated between a first electrode (10) and a second electrode (6) one of which is insulated and another of which is not insulated and wherein a respective surface of each of the electrodes face one another. The first electrode (10) is rotated so as to induce relative rotation between the first electrode and the second electrode; and liquid water is conveyed on to a surface of the first electrode facing the second electrode close to the axis of rotation (4) of the first electrode whereby the liquid water advances outward through the corona discharge zone towards a periphery of the first electrode under the action of centrifugal force caused by rotation of the first electrode.

The invention relates to a process for electrolysis comprising a cathode and an anode comprising a catalyst, both the cathode and anode at least partly immersed in an electrolyte, the process characterised in that the electrolyte at least partly inhibits further oxidation of a product formed at the anode. Typically the catalyst comprises one or more metal-(Group VIb) semiconductors, and one or more metal-(GroupVIb))-phosphorous species.

A universal chemical processor (UCP) including a reactor vessel having a central longitudinal axis and main chamber comprises a first inlet port for a main feedstock, a second inlet port for a fluidizing medium and a third inlet port for one or more reactants. The UCP also includes a reactive radioactive chemical processor (R.sup.2CP) that contains a radioactive element positioned extending along the longitudinal axis in the main chamber. In operation, a fluidized bed can be supported in the main chamber when a fluidizing medium and feedstock are supplied to the main chamber through the first and second inlet ports and the radioactive element of the R.sup.2CP emits ionizing radiation that is capable of ionizing feedstock and reactants, inducing chemical reactions, and sterilizing and decomposing any organic materials within a radiation zone.

The disclosure deals with system/apparatus and corresponding and/or associated method for an open plasma reactor assembly provided to study pulsed reactive species produced in a dielectric barrier discharge (DBD) in He—H.sub.2O and He—H.sub.2O—O.sub.2 mixture in atmospheric conditions using photo fragmentation laser-induced fluorescence (PFLIF). The objective is to detect and quantify hydroxyl radicals and hydrogen peroxide produced in the DBD. An OH laser-induced fluorescence (LIF) signal is acquired from LIF (using 282 nm laser) whereas LIF from OH generated from H.sub.2O.sub.2 is measured by from the PFLIF signal (using 213 nm+ 282 nm lasers). A known concentration of H.sub.2O.sub.2 in He serves to calibrate for H.sub.2O.sub.2 while the OH is calibrated with a chemical model. For both gas mixtures, there is both OH and H.sub.2O.sub.2 production in the discharge, while the H.sub.2O.sub.2 concentration was noticeably increased for the added O.sub.2 case.
