The development of new routes towards the generation of environmentally friendly solar fuels, such as molecular hydrogen (H2) for use in fuel cells, is a grand challenge facing the scientific community. Water splitting, viewed as the sum of the hydrogen evolution reaction (HER) and water oxidation reaction (WOR), represents one of the most promising, yet(More)
OBJECTIVE To study the chemical constituents in the twigs and leaves of Ligustrum obtusifolium. METHOD Seven compounds were isolated from the ethanol extract of the twigs and leaves by polystyrene resin RA and silica gel column chromatography.
