Light-driven restructuring generates nanoisland NiIr alloy for efficient methane dry reforming.

ABSTRACT: The simultaneous utilization of methane and carbon dioxide via dry reforming holds promise for sustainable syngas production, yet conventional thermocatalytic processes suffer from energy-intensive operation and catalyst deactivation. Here, we report a light-driven methane dry reforming strategy utilizing sinter-resistant nano-island alloys catalyst, which are dynamically evolved from partially oxidized NiIr nanoclusters anchored on TiO₂ under photoexcitation. In situ characterization reveals interfacial charge oscillations on the catalyst induce a support-Ni-Ir electron transfer pathway, stabilizing oxidized Ni linkages while electronically modulating surface Ir sites. This dual functionality promotes CH_xO* intermediate formation, suppressing coking during 100-h oper
