Article Synopsis
- Light-driven oxidative coupling of methane (OCM) has potential for producing valuable multi-carbon chemicals but faces challenges due to low activity.
- The study combines bismuth oxide (BiO) and gold (Au) on titanium dioxide (TiO) to enhance conversion rates, selectivity, and durability in photocatalytic OCM through improved catalytic design.
- The hybrid catalyst achieves a high conversion rate of 20.8 millimoles per gram per hour and 97% selectivity for C products, with the lattice oxygen in BiO playing a key role in the reaction stability via the Mars-van Krevelen mechanism.
Electrochemical nitrogen oxide ions reduction reaction (NO RR) shows great opportunity for ammonia production under ambient conditions. Yet, performing NO RR in strong acidic conditions remains challenging due to the corrosion effect on the catalyst and competing hydrogen evolution reactions. Here, we demonstrate a stable LaSrNiFeO perovskite oxide for the NO RR at pH 0, achieving a Faradaic efficiency for ammonia of approaching 100 % at a current density of 2 A cm in a H-type cell.

Herein, we report a direct photocatalytic methane-to-ethylene conversion pathway involving the formation and dehydrogenation of alkoxy (i.e.
