Thermochemistry and kinetics of graphite oxide exothermic decomposition for safety in large-scale storage and processing.

ABSTRACT: The success of graphene technologies will require the development of safe and cost-effective nano-manufacturing methods. Special safety issues arise for manufacturing routes based on graphite oxide (GO) as an intermediate due to its energetic behavior. This article presents a detailed thermochemical and kinetic study of GO exothermic decomposition designed to identify the conditions and material compositions that avoid explosive events during storage and processing at large scale. It is shown that GO becomes more reactive for thermal decomposition when it is pretreated with OH^- in suspension and the effect is reversible by back-titration to low pH. This OH^- effect can lower the decomposition reaction exotherm onset temperature by up to 50 degrees of Celsius, causing o
