Systems and methods are provided for direct conversion of methane and/or ethane to methanol. The methods can include exposing methane to an oxidant, such as O, in a solvent at conditions that are supercritical for the solvent while having a temperature of 310&#xb0; C. or less, or about 300&#xb0; C. or less, or about 290&#xb0; C. or less. The solvent can correspond to an electron donor solvent that, when in a supercritical state, can complex with O. By forming a complex with the O, the supercritical electron donor solvent can facilitate conversion of alkane to methanol at short residence times while reducing or minimizing further oxidation of the methanol to other products.

Tungsten bronze thin films and method of making the same

Systems and methods are provided for direct methane conversion to methanol. The methods can include exposing methane to an oxidant, such as O, in a solvent at conditions that are substantially supercritical for the solvent while having a temperature of about 310&#xb0; C. or less, or about 300&#xb0; C. or less, or about 290&#xb0; C. or less. The solvent can correspond to an electron donor solvent that, when in a supercritical state, can complex with O. By forming a complex with the O, the supercritical electron donor solvent can facilitate conversion of methane to methanol at short residence times while reducing or minimizing further oxidation of the methanol to other products.

This disclosure provides a unique approach for the synthesis of non-stoichiometric, mesoporous metal oxides with nano-sized crystalline wall. The as-synthesized mesoporous metal oxide is very active and stable (durability &#x3e;11 h) electocatalyst in both acidic and alkaline conditions. The intrinsic mesoporous metal oxide serves as an electrocatalyst without the assistant of carbon materials, noble metals, or other materials, which are widely used in previously developed systems. The as-synthesized mesoporous metal oxide has large accessible pores (2-50 nm), which are able to facilitate mass transport and charge transfer. The as-synthesized mesoporous metal oxide requires a low overpotential and is oxygen deficient. Oxygen vacancies and mesoporosity served as key factors for excellent performance.
