摘　　要：A novel glow discharge plasma solid-state reduction route was developed to synthesize molybdophosphoric heteropoly blues(MB). The glow discharge plasma played a role of activating hydrogen mole-cules and generated a lot of active species which rapidly induced molybdophosphoric heteropoly acid(PMo12) to form four-electron MB within several minutes. Analyses of the heteropoly blues via UV-Vis, FTIR, XRD and Py-IR confirmed that the materials retained not only the similar Keggin structures of their oxidized parents, but also exhibited more surface acidity due to protonation.A novel glow discharge plasma solid-state reduction route was developed to synthesize molybdophosphoric heteropoly blues （MB）. The glow discharge plasma played a role of activating hydrogen molecules and generated a lot of active species which rapidly induced molybdophosphoric heteropoly acid（ PMo12 ） to form four-electron MB within several minutes. Analyses of the heteropoly blues via UV-Vis, FFIR, XRD and Py-IR confirmed that the materials retained not only the similar Keggin structures of their oxidized parents, but also exhibited more surface acidity due to protonation.
