High photocatalytic yield in the non-oxidative coupling of methane using a Pd-TiO₂ nanomembrane gas flow-through reactor.

ABSTRACT: The photocatalytic non-oxidative coupling of methane (NOCM) is a highly challenging and sustainable reaction to produce H₂ and C₂₊ hydrocarbons under ambient conditions using sunlight. However, there is a lack of knowledge, particularly on how to achieve high photocatalytic yield in continuous-flow reactors. To address this, we have developed a novel flow-through photocatalytic reactor for NOCM as an alternative to the conventionally used batch reactors. Me/TiO₂ photocatalysts, where Me = Au, Ag and Pd, are developed, but only those based on Pd are active. Interestingly, the preparation method significantly impacts performance, going from inactive samples (prepared by wet impregnation) to highly active samples (prepared by strong electrostatic adsorption -
