We prepared supported rhodium catalysts using relatively simple procedures. The main effort was to atomically disperse the rhodium species, which was achieved using a heat treatment protocol on the ...

While some researchers are proposing the idea of using a platinum catalyst to keep methane out of the atmosphere, a group of British, Chinese and American scientists demonstrated, for the first time, ...

The direct oxidation of methane -- found in natural gas -- into methanol at low temperatures has long been a holy grail. Now, researchers have found a breakthrough way to accomplish the feat using a ...

The catalytic aldol condensation reaction represents a pivotal method for synthesising acrylic acid through the coupling of simple carbonyl compounds such as acetic acid, formaldehyde and methanol.

A simple, low-cost method of directly converting natural gas into useful chemicals and fuels, using the precious metal gold as a key ingredient, has been proposed. A simple, low-cost method of ...

Hydrogen is a vital feedstock for chemicals and fertilizers, and it’s gaining traction as a transportation fuel. But it is made today by heating natural gas to 1000°C, emitting 9–12 kg of carbon ...

To make an ester, a hydrogen atom must be removed from the hydroxyl group (–OH) of the alcohol. The –OH portion of the acid's carboxyl group must also be removed. The hydrogren atom and the -OH ...

Esters are usually synthesized from an alcohol and an acid, most frequently, a carboxylic acid. In some cases, an epoxide is used instead of the alcohol; or an acid halide or anhydride replaces the ...

Sodium oxide and potassium oxide dissolve in water to produce alkalis: • Na 2 O(s) + H 2 O (l) → 2 NaOH (aq) • K 2 O(s) + H 2 O (l) → 2 KOH (aq) • 2K(s) + 2H 2 O (l) → 2KOH (aq) + H 2 (g) + heat ...
