Sub-50 nm perovskite-type tantalum-based oxynitride single crystals with enhanced photoactivity for water splitting by Jiadong Xiao, Mamiko Nakabayashi, Takashi Hisatomi, Junie Jhon M. Vequizo, Wenpeng Li, Kaihong Chen, Xiaoping Tao, Akira Yamakata, Naoya Shibata, Tsuyoshi Takata, Yasunobu Inoue, Kazunari Domen

“…The SrTaO2N nanocrystals modified with a tailored Ir–Pt alloy@Cr2O3 cocatalyst evolved H2 around two orders of magnitude more efficiently than the previously reported SrTaO2N photocatalysts, with a record solar-to-hydrogen energy conversion efficiency of 0.15% for SrTaO2N in Z-scheme water splitting. Our findings enable the synthesis of perovskite-type transition-metal oxynitride nanocrystals by thermal nitridation and pave the way for manufacturing advanced long-wavelength-responsive particulate photocatalysts for efficient solar energy conversion.…”
