Abstract
A method for preparing a transition-metal adamantane carboxylate salt is presented. The method includes mixing a transition-metal hydroxide and a diamondoid compound having at least one carboxylic acid moiety to form a reactant mixture, where M is a transition metal. Further, the method includes hydrothermally treating the reactant mixture at a reaction temperature for a reaction time to form the transition-metal adamantane carboxylate salt.

A method for preparing a transition-metal adamantane carboxylate salt, the method comprising:
- mixing a transition-metal hydroxide and a diamondoid compound having at least one carboxylic acid moiety to form a reactant mixture, where M is a transition metal;
- and
- hydrothermally treating the reactant mixture at a reaction temperature for a reaction time to form the transition-metal adamantane carboxylate salt.
A method for preparing a nanocomposite, the method comprising:
- thermally decomposing a transition-metal adamantane carboxylate salt to form the nanocomposite;
- the transition-metal adamantane carboxylate salt prepared by:
- mixing a transition-metal hydroxide and a diamondoid compound having at least one carboxylic acid moiety to form a reactant mixture, where M is a transition metal;
- and
- hydrothermally treating the reactant mixture at a reaction temperature for a reaction time to form the transition-metal adamantane carboxylate salt.
A catalyst system comprising:
- (a) a transition-metal adamantane carboxylate salt prepared by:
- mixing a transition-metal hydroxide and a diamondoid compound having at least one carboxylic acid moiety to form a reactant mixture, where M is a transition metal;
