We report an efficient, highly selective, and low temperature graphene-catalyzed reaction process for one-step oxidation of benzene to phenol with hydrogen peroxide as the oxidant. The chemically converted graphene (CCG) from small graphite was used catalyst. conversion reaches 18%, being sole product. catalyst reusable very stable. By XPS, C K-edge X-ray absorption spectra, benzene-TPD, kinetic measurements, it concluded that moderate H2O2 activation rate, good adsorption ability, balanced control over are responsible outstanding catalytic performance metal-free
