Reductive-defect-suppressed titanium oxynitrides via Ca 3 N 2 -assisted topochemical nitridation
Key Points
The aim is to synthesize titanium oxynitrides using a method that avoids reductive defects.
Conducted one-step topochemical nitridation using Ca 3 N 2
Focused on anion exchange between BaTiO 3 and nitrogen
Employed ammonia-free conditions for the reaction
Achieved successful anion exchange with reduced Ti 3+ related defects
Produced bright-orange titanium oxynitrides
Demonstrated improved material stability through defect suppression
Abstract
One-step, ammonia-free topochemical nitridation using Ca 3 N 2 enables 3O 2− /2N 3− anion exchange from BaTiO 3 while suppressing Ti 3+ -related reductive defects, yielding bright-orange oxynitrides.
