Graphite oxide as a support for palladium and rhodium complexes, assessed as catalysts for the partial hydrogenation of 1-heptyne

Abstract

GO was prepared from a natural graphite (Sigma Aldrich) according to Brodie´s method: 22 graphite (99.98wt %C) and NaClO 3 were mixed in a flask in an ice-bath. Fuming HNO 3 was then added drop wise. Another portion of acid was added after a time and the slurry was heated to 333K and kept for 8h. The heating rate (1.5Kmin -1
