MICROREACTORS AND METHODS FOR GENERATING HYDROGEN PEROXIDE

摘要

Microreactors (10) and methods for generating hydrogen peroxide are disclosed. More specifically, microreactors (10) and methods are provided for the batchwise generation of hydrogen peroxide in which respective hydrogen and oxygen electrolysis chambers, and a hydrogen peroxide reaction chamber is fluid-connected to and positioned physically between, the electrolysis chambers. In specially preferred embodiments, the hydrogen peroxide microreactor (10) of the present invention will be in the form of a silicon chip reactor body having a pair of electrolysis channels (14-1, 14-2), reactant channel (14-3) positioned between the electrolysis channels, and at least one (preferably several) connector channel(s) (14-4) which fluid-connect(s) the pair of electrolysis channels (14-1, 14-2) with said reactant channel (14-3). A pair of electrodes (16-1, 16-2) is provided so that each is in operative association with a respective one of the electrolysis channels (14-1, 14-2). A catalyst for forming hydrogen peroxide is also provided so as to be in operative association with the reactant channel (14-3).
