Methanol is seen as a viable option as a fuel in futuristic fuel cell
vehicle applications and its selective oxidation to numerous high value
chemicals such as dimethyl ether (DME), formaldehyde and hydroformylation
products demonstrates it as a chemical platform. Both uses of methanol involved
catalytic chemistry for efficient energy usage.

The focus of the current research is on the selective oxidation of methanol to
various chemical products using catalytic chemistry. The catalysts were grouped
into two categories, which include bulk catalysts (silica, ceria,
silica-alumina, titania, copper, and aluminum phosphate) and supported metal
catalysts (metals immobilized onto the various bulk catalysts). The acidic
catalysts, which include silica-alumina and aluminum phosphate, demonstrated a
tendency towards DME. Alternatively, ceria, silica, and the supported metal
catalysts showed selectivity towards formaldehyde and combustion products.
Currently, catalyst alterations to maximize selectivity for a single route are
being investigated.
