New Findings in Alcohols Described from Inner Mongolia Normal University (Aerobic Oxidation of Alcohols on Au Nanocatalyst: Insight to the Roles of the Ni-Al Layered Double Hydroxides Support)

By a News Reporter-Staff News Editor at Life Science Weekly -- Researchers detail new data in Alcohols. According to news reporting originating in Hohhot, People's Republic of China, by NewsRx journalists, research stated, "Au nanoparticles (NPs) supported on Ni-Al layered double hydroxides (LDHs) were shown to be efficient heterogeneous catalysts for the highly selective oxidation of alcohols to the corresponding aldehydes or ketones under base-free or even solvent-free conditions with O-2 as the sole oxidant. The Au NPs can be uniformly distributed on Ni-Al LDHs support, which is beneficial to the catalytic activity."

The news reporters obtained a quote from the research from Inner Mongolia Normal University, "In addition, the weak Bronsted basic property of the support enables the aerobic oxidation of alcohols under base-free conditions. More importantly, unlike Al2O3, which is inert, Ni-Al-LDHs are redox-actively involved in prompting the electron transfer to O-2 via the Au nanocatalyst because of the presence of Ni-II. Both of the basic and the redox properties of Ni-Al-LDHs can be tuned by adjusting the ratio of Ni:Al to achieve the best synergistic effects between Au NPs and the supports."

According to the news reporters, the research concluded: "The activity of the obtained Au catalysts was found to be structurally associated with the arrangements of NiO6 and AlO6 octahedra in the surface hydroxide layers which were different from the bulk Ni:Al ratio."
