Abstract:
Dual heterojunction engineering on TiO2 enables the spatial decoupling of active sites, where holes mediate C-H activation and electrons drive O2 activation. This synergistic strategy achieves a remarkable C2 hydrocarbon production rate of 1.7 mmol g-1 h-1 with 83% selectivity and a remarkable 45-hour stability in the photocatalytic oxidative coupling of methane.

Conjugated systems containing an even number of π-electron pairs undergo a conrotatory ring closure. For example, thermal electrocyclization of (2E,4E)-2,4-hexadiene, a conjugated diene containing two π-electron pairs, gives trans-3,4-dimethylcyclobutene.
